Learn to Dive
Scuba Diving-learning techniques diving
In this section will discuss standard procedures and techniques learned diving. Prospective divers are expected to understand and practice properly. This is very useful for actual diving activities.
Procedures predive learn diving
Procedure before dives including equipment preparation, preparation of divers, and perform inspections before entering learn diving and into the water.
Preparation Equipment – learn diving
Before a dive, the diver must perform inspections of equipment used to learn diving. The equipment must be standard, should not be arbitrary, and comfortable to wear.
Selam tube – learn diving
Preview the outside of the tube if there is rust, cracks, dents, etc. which indicates abnormal tube wall.
Make sure the mechanical backup (reserve mechanism) is closed (the lever is above) indicates the tube is ready for use.
Measure the pressure using a pressure gauge tube through the following procedures:
Replace the pressure gauge on the tool O ring seal face with a valve tube.
Close the appliance valve pressure gauge and then open the mechanical backup (move the lever down). Slowly open the faucet tube. Look at the movement of the tool pressure gauge.
Read the pressure on the pressure gauge tool. The tube should not be used when the pressure is insufficient for diving.
Close the faucet tube and open the valve pressure gauge and allow air to flow freely.
If the appliance pressure gauge is showing zeros, remove the tool from the tube.
If the pressure tube 50 psi or more of the expected pressure, open the faucet tube to remove excess pressure and then measure again by means of the pressure gauge.
Harness straps and Backpack – learn diving
Check the power harness. See if already started to loosen or not.
Adjust the strap according to the divers and try to test whether the quick-release mechanism nice / not.
Backpack check whether there are cracks and other conditions that make diving unsafe.
Breathing Hose (hose / pipe)
Check the hose from leaks and cracks.
Check the hoses relationship with regulators and mouthpiece, by trying to pull the hose.
Check hose clamps if there is rust and other damage, if necessary replace it with a new clamp.
Regulators and How to Assemble Tube – learn diving
Make sure the pressure in the first stage had been set 135 psig or in accordance with the issuing plant.
Open faucet tube slightly. This is done because of the possibility of dust / dirt in the valve hole can be detached / pushed out.
Replace the regulator on the tube, make sure the O ring is in place (yoke).
Before opening the suction through the mouthpiece to control whether or not the regulator.
Open the tap to the brim, and then return the faucet half a lap. It is menghindarai damage to the faucet.
Try breathing 2-3 times using a mouthpiece.
Is there a leak check on the regulator to hear the hiss of air. If it is not visible input into the water tank.
If memasag SPG connect with estuary on the first stage that reads HP. SPG navigate to a safe place when opening the taps.
Blow BC to determine leakage dah press by hand so that air out.
Never suck in air for blowing air contains a lot of carbon dioxide.
Attach the hose BC at the mouth of the low pressure.
Check the seal masks and strapnya.
Check whether there are cracks on the seal / skirt or a glass mask.
Check for cracked / broken / ripped the strap (the part that attaches to the leg)
Check the fin blade crack etc.
Check the sharpness of the knife dive
Make sure the blade is attached to both the sheath.
Make sure the blade is removed and not easily separated from the sheath.
Place in the easily accessible and safe. Do not be around the weight belt, because it can be easily separated.
See snorkel if there is blockage.
Make sure the valve is functioning properly.
A weight belt
Check the condition of belts ballast.
Make sure the amount of ballast that will be used.
Check whether the quick-release buckle function.
Make sure the clock is in good condition and a great time. Equate time with the diving team.
Check strap watch, too tight complicate the movement, too loose to be easily separated.
The depth gauge (depth gauge) and Compass – learn diving
See the depth gauge needle pointing zeros sea surface. If you need to check with the other as a comparison.
If the compass needs to be checked in the same way.
Check all other diving equipment learning that will be used include tubes and spare regulator. Do not forget to check clothing mainly diving with a dry suit.
Diver preparation and Briefing – learn diving
Once the equipment is ready and in good condition, then the diver is given a briefing before diving learn namely regarding:
Time and it dives
Each task divers
Difficulties, dangers to be faced, and emergency procedures.
Although learning diving can be required to install the equipment itself, but with the help of an assistant would be better. Here is the sequence wearing diving equipment that must be considered:
Wetsuits. Ensure protection wetsuits diving suit field conditions.
Booties and hood
If rescued assistant, ask to position the tube and divers set and binding harness. Scuba tube is positioned as high as possible, but do not interfere with the view of divers. Make sure it is plugged BC.
Other equipment (clock, compass, depth gauge)
A weight belt
Mask and snorkel
Using Tools on Surface and in the Air
If it does not allow the use of the equipment on land, it can be used scuba gear surface or in the water. It is often practiced in the class pool.
How to put on the surface as follows:
Ensure that BC filled with air and create a floating tube.
Use fins, mask and snorkel and went into the water.
Kempiskan BC slightly so that the tube is in control.
BC and tube wear. Could the one hand, two hands or directly (with menjungkirbalik tube backward over the head, or by swimming down BC, putting two hands). Make sure the neck is not twisted hose and BC are installed correctly.
Success depends experiences and terrain conditions.
How to install underwater as follows:
All the equipment is in the water unless wetsuits and watches.
Entry into the water, take a breath twice, and did dugdive to the equipment.
First grab mouthpiece, remove the clog water, breathe with ease.
Pairs BC and tubes, do the same with the surface, make sure the neck is not twisted hose and BC correct position.
Wear a mask followed by a fin and mask clearing.
Use a weight belt.
Rise to the surface or dive with a buddy.
Success depends experiences and terrain conditions.
Before entering into the water should be carried out inspections predive namely:
Ensure the physical and mental readiness before going into the water.
Make sure the divers already have minimum equipment (SCUBA, mask, BC, belts ballast, diving knives, fins, clock, and depth gauge). When you use the buddy line need only one hour dive and the depth gauge.
Make sure the tube has been measured pressure and can be used according to plan dives.
Make sure that all quick-release buckle in range.
Make sure the rod sinker so easily removed and do not get caught with other equipment.
Make sure BC is not depressed so easily inflate.
Check the position of dive knives.
Make sure the tap is open tube half (with full opening and closed u to o).
If using double hose, make sure the outlet pipe is on the left and facing up.
Try breathing with the mouthpiece few times and make sure to breathe comfortably.
If using a single hose, drain and press the release button, hear the air out. Then try to breathe with mouthpice.
Make sure the reserve mechanism in the closed position (lever is above).
Water Entry and Descent
Now the diver is ready to go into the water and down into the depths. Inspections carried out by diving partner.
There are several ways into the water, it depends on the terrain and runway used dives. If possible entry into the water using the ladder, especially if the water situation is not known.
The following rules are applied in all methods of entry:
Note the timing before entry.
Bring the chin to the chest. Hold the tube with one hand to avoid conflict scuba gear in the back of the head.
Press the mask with fingers (index and middle) and the mouthpiece with the palm of the hand.
Here is the method of water entry:
Step-In Method / Standing Front Entry – learn diving
This method is often used and is often used when a static grounding such a large ship or pier. Divers need a big step (Giant Step), and the feet must be kept in stride without motion leaps and do not be drawn again. Let the feet remain outstretched to touch the surface of the water. Keep the body slightly inclined forward so that the head does not hit the tube. At the time the foot hits the water, both legs clenched back to keep the diver to remain on the surface.
Real Roll Method
When using a small boat or raft, using this method, because if the diver is wearing full equipment standing beside the ship will affect the balance of the ship that eventually made the divers difficult to maintain balance.
To do this diving divers learn to sit on the sidelines and mengahadap into the boat. With chin bent and hold the mask and mouthpiece, divers rolled back. Use power so full somersault.
Position learn diving diver sitting on the edge of the boat parallel to the hull of the boat. This method is rarely used. By holding the mask and mouthpiece divers plunge toward the water. This method is commonly used by the under water demolation team (UDT) or squads underwater crushers, which should go into the water while the rubber boat still go fast.
Front Roll / Sitting front entry – learn diving
How to learn diving this would be very useful if it will enter the water from the lower dock or plate form. Divers sitting on the edge of the boat, with a dangling fin and overlooking the water. Then, with the body leaning forward, place your hands on either side, turn around and go into the water.
Rear Step-In Methode
Modikasi of Step-In. The difference divers facing the ship, and then step back away from the ship.
Water Entry Coast Region
Depending on wave conditions and runway beach. If the waves calm and the runway sloping beach, can walk on water with fins removed until the water deep enough to swim.
If the big waves and steep coastal runway, use fin and the retreat back to the waves. After deep enough to swim back to the body turn and swim the waves break.
Surface Swimming / Snorkeling – learn diving
Close to where the ship was supposed to learn diving. When swimming, the diving colleagues should have visual contact with other colleagues to swim smoothly and do not hit each other. The most important factor in swimming with SCUBA is relax movement to conserve energy. Divers must still wear a mask and breathing through a snorkel. If using a regulator, hold the mouthpiece so that air does not flow freely out SCUBA system.
The diver should only use the legs to pedal and little use of the thigh. Do not get raised fin out of the water. Divers can change position with mengahadap back into the water and keep it moving with fin strokes. It could also pumping BC, but before getting into the BC must be emptied first.
Surface Predescent Check
Before descending to kedalaman.Penyelam have to do a final check of the equipment. The divers must:
Check breathing with the mouthpiece. Air should be out in accordance with the negative pressure supplied divers and do not suck up to the powerful.
Check whether there is leakage partner equipment is usually located at the junction (regulators, faucet tube, hose, etc.).
Check whether the partner strap folded / no and look baggy.
Check whether the incoming water masks. If the penetration of water is removed with a mask clearing.
Check bouyancy. Bouyancy should be neutral to regulate the air inside the BC. Conditions are considered neutral if the water level is above the limit mask without moving fin.
If using dry money, see if there are leaks.
Orientation position using a compass or other use.
Please tick OK when it is finished and ready to go down into the water.
Bouyancy Control – learn diving
To set keterapungan, divers must control boyancy. During the dive bouyancy should be neutral in the sense diver floating in the water. If riding try not to use BC, except for emergencies or difficult upward.
Bouyancy usually controlled mechanical buttons on the left shoulder, set the incoming air discharge in BC with this button. If you want to go down, then move forward in a horizontal position and then silence, as he set the BC button. If the water level was already in the eye with the head forward deem it neutral bouyancy.
How to set up BC:
On the surface
Divers are in place in the standing position with his mouth full of BC m eniup her through the oral inflator. Romphi control buoyancy by regulating the air in BC to limit water level is in the eye.
In the deep
Divers at a depth of neutral buoyancy set by filling air to the BC either through oral inflator and mechanical inflator.
To go down to learn diving diver can swim into, using a rope to pull the body down to the bottom, or browse the arch off the coast. Speed down depending equalizing process is carried out but no more than 75 feet / minute (25 m / min? 0.42 m / sec). If one of the friends had trouble equalizing, then it is better not to go down, go up a little so that better and do equalizing back. If you continue to have equalizing immediately rose to the top and abort the dive.
If the visibility in the water is very less, spread arms to avoid obstacles.
After reaching the desired depth then check and see the surrounding environment.
Review of the previous chapter, perform equalizing from a depth of 4 feet (1.3 meters), not to be initiated when already ill. Do not be too hard to do so. Equalizing methods there are 2 ways Valsalva maneuver and Frenzel.
Valsalva maneuver is blowing air against the closed lips and nose and tongue toward the back of the pharyngeal cavity to increase the pressure transmitted into the middle ear through the eustachian tube. This maneuver can also open the eustachian tube is closed. Commonly called straining.
Frenzel maneuver is to swallow with the tongue to the back where the mouth closed and nostrils in the press (punch in the nose).
Bottom time is the main thing to learn diving, this is because the air is very limited. Divers must mengehemat energy and can suddenly stop dives and rises to the top. Divers also have to be alert and see the condition of the other divers.
In the new divers learn diving is usually nervous and breathing rapidly and deeply. Teach so that breathing relaxed, slowly, and unhurried. If still can not be solved immediately rise to the surface.
Never did ± ¡° skip breathing¡ which aims to conserve air. This resulted in hiperkapnea.
Divers can experience difficulty breathing on the mouthpiece or less when the air was sucked and should be firmly, if the tube is still a lot filled with air, it caused a problem regulator, immediately rise to the surface.
It can also be the case if the tube is running out, for it to open up mechanically and immediately rose to the surface. If using SPG, stop dives when the pressure dropped to 500 psi tube (a tube) or 250 psi (two tubes).
The water may be slightly into the mask. This can help clear the fog stuck to the glass. However, large amounts will certainly not comfortable and should be issued with a mask clearing.
If the mask has a drain valve, tilt the mask towards the drain valve (usually with a drain valve down when in front), press the mask slightly prominent and remove air rapidly through the nose. This makes the water out through the valve.
If the mask does not have a drain valve. Use the appropriate method of drawing. Which is often used is the head-up method. Ie lift your head so that the mask slightly upwards so that the water collected in the bottom area. Press the top of the mask that seals the bottom of a rather open and immediately remove the air through the nose. Remove the pressure quickly so seal the bottom of the stick back.
Do not panic learn diving in doing this. Try practicing by using a snorkel alone so that increased confidence when using SCUBA.
Selection of masks also have to consider the comfort factor in making mask clearing. If the mask is easy to enter the water immediately abort the dive, and replace it with another mask because the air will be discharged to mask clearing. Often mask clearing also lowered vigilance in diving. Use antifog before getting into the water, and do not rely on clearing mask to remove fog.
Hose and Mouthpiece Clearing – learn diving
Mouthopiece and hose can enter the water when removed from the mouth and into the water. If using a single hose, it’s not a big deal because to remove the water could drain the push of a button (usually in front of the mouthpiece).
For double hose, divers must diving horizontal position and hold the mouthpiece. Then blow air into the mouthpiece so that the incoming water out through the discharge pipe (exhaust). Do not breathe in, appropriately alone. If there is still water that makes doing the same thing and then natural breathing. If you can not breathe, somersault backwards so that the air flows freely from the regulator.
Do not panic when the mouthpiece out of the mouth. Do not panic looking for her hose. If off there are two ways to find mouthpiece that was behind.
Tilt the body to the right and right hand stretched out to the rear and pull it forward as pedaling motion. Hose will lie across the hand and will be held in check.
The second way is to tilt the left hand tube diving to the right from behind. The right hand moves up and looking for a relationship with the first stage hose. The bias for the top pipe mouthpiece is right. Having found a connection hose then seek mouthpiece.
Swim technique – learn diving
On the dives, all the thrust comes from the legs. Hands only used for maneuvering. Kick wide leg, relaxed, with a style boost primarily from the thighs. Knee and ankle should relax. Rhythm kicking leg must be maintained not to make tired or cramps.
If you already adept can use the dolphin kick. Dolphin kick is done by moving the second straight legs rhythmically like a butterfly.
Komunikas learn diving
For recreational divers in the water can use hand signals. Actually communication in SCUBA consists of through-water communication systems (AM and SSB), hand signals (hand signals), slate boards (slates), and line-pull signals.
If the diver is still at the surface can use voice. For that to memorize the hand signals are often used in submarines.
Buddy Diver – learn diving
learn diving is a high risk activity, all the more so when the dive was done alone. In the event of an emergency that endanger the safety of body and soul, there will be no one who knows and helps those difficulties. Therefore the world diving embrace and practice the principles of dives that says never dive alone. So dive always in a team with system partners (buddy system).
The following basic rules buddy:
Always maintain contact with diving partner. If the visibility is good, make sure the dive partner in sight. If visibility is poor as highly turbid water, use a buddy line.
Know the meaning of the hand gestures and line pull signal.
If the cue had been given, it must be responded immediately. If no response then consider an emergency situation.
Monitor the movement and condition of diving partner. Know the symptoms of the disease dives. If the dive partner looks unusual, make sure the cause, and take action to eliminate them.
Do not leave the dive partner partner despite being trapped and can not escape without help. If it can not be helped, calling the other divers with diving spots mark where our partner is trapped.
If one partner scuba diving cancel for various reasons, then the other must also rise to the top.
Know how to do the buddy breathing.
Buddy Breathing – learn diving
If the diver ran out of air, or damage SCUBA, the mouthpiece can be used together with diving partner. If the study had octopus diving course very easy. If only one mouthpiece, then do buddy breathing. Buddy breathing is done by sight, and alternately breathing while rising to the surface. The procedure is as follows:
Lack of air diver should be calm and give hand signals to partner with pointing toward the mouthpiece.
Both divers mutual holding each arm so the distance is not too far away. Give an octopus. If there is no further to selanjutmya procedure.
Divers who helped breathe first and then give mouthpiece to divers who helped. Divers who helped do not hold the mouthpiece. Mouthpiece directed by divers rescuers helped towards the mouth. Both divers must maintain hand contact with the mouthpiece.
Mouthpiece may take in water. Therefore press the drain before it goes into the mouth or exhale into the mouthpiece before taking a breath.
Divers who helped take two breaths and return to the helper. Press the drain and auxiliary divers breathe twice.
Do this with the rhythmic and do not be hasty. Do not go up to the top if not done the right cycle.
If it rises to the surface do not forget to exhale to avoid barotrauma.
Adaptation to the Water Conditions – learn diving
By looking at underwater conditions are different, then the diver must do the adaptation.
If a muddy dive. Divers should not touch the bottom, just 2-3 feet above the mud. Avoid pedaling too strong so the mud can rise to the top.
Avoid touching the coral and rocky base because it can hurt the dam scratch the skin.
Avoid depth changes suddenly. Keep the depth of the dive, do not go up and down.
Do not veer too far from the dive.
Guard against the effects of light in the water. Objects look bigger and closer.
Wary of strong currents, especially the flow gap. If carried away, relax, do not fight. If the flow has started weak berenaglah avoid it. Do not try to fight the current.
After the dive time is reached, then one of the divers must be signaled to rise to the top. Divers should not rise rapidly exceeding 30 feet / min USN (0.12 m / sec). Breathing normally, do not hold your breath during the climb because it causes air embolism.
When it rises to the top, do by turning the body 360 degrees so it can look around and one hand raised up to see if there is blocking. Should ride together with buddy.
To avoid injury when surfacing divers should always look up, reaching and then came slowly rotates 360 ° while keeping an eye on the surface. This maneuver is very important, especially in the final stage of 10 feet to get to the surface.
The technique appears under control (slow ascent) to learn diving
Divers should always rises to the surface at a slow pace. Safe speed for the ride is 60 feet per minute. How to know the speed of the easiest is to look at the smallest air bubbles and must not precede.
The technique appears free – learn to dive
Divers did surface dive, swim to the bottom and then releasing snorkel and go up to the surface slowly while exhaling continuously until surfacing. The position of head thrown back, the view and the hand pointing upwards.
Emergency Swimming Ascent (ESA) – learn to dive
In the event of air in the tube runs, a diver must perform an emergency arises technique by removing the regulator from his mouth, rising vertically to the surface slowly and exhale continuously until it reaches a depth of 10 feet, at the depth of body position changes be horizontal, head looked up, hand it expands, until he came to the surface. In the particular circumstances of weight belt can be removed to gain additional positive buoyancy.
Ascent Freeman Emergency Procedure
If the SCUBA diver ran out of air or pinched something, and partner dive too much to help it do this procedure:
Remove the equipment and hand-held objects.
Remove the ballast belt.
If SCUBA stuck and had to be abandoned, BC release buckle on the waist, chest, shoulders, and groin. Remove the one hand first, then the other hand again. Another method is to menjungkirbalik scuba tube on top of the head and thus both hands instantly regardless. Make sure the hose is not pinched neck.
If you just run out of air, remove the object that is in the hands, remove the ballast belt, and develop BC. Do not remove the tube SCUBA except absolute reason.
If the diver is unconscious, having to swim toward her partner and develop BCnya while carrying the victim upwards. Ballast belt also can be released. Hold the victim, do not let loose.
Exhale during the ride to the surface, do not hold and panic.
If divers are required to do a Deco Stop, then stopped at a depth of Deco Stop. Each diver or one person can calculate the time Deco. After the time Deco is reached, up to the surface or hereafter Deco station.
If it is on the surface, then breathe snorkels. This is done because the tube is up and save the air .. To determine the water inlet snorkel typically heard incoming water in the pipe snorkel on the left. Snorkel clearing is done in two ways:
How to remove water from the snorkel by means of blowing air into the snorkel so the water in the snorkel missing First remove the water. The water will come out through the top hole and drain valves and we can breathe.
Water displacing method
Snorkel clearing the way this method is helpful, because it does not need air blowing hard. By the time the diver approaches the surface with his hands up tengadahkan head so that the top end of the snorkel downward by exhaling slowly and continuously will result in exhaled air to hold water get into the snorkel while the divers headed upward. After divers reached the surface and swim position, then he will be able to breathe without having to blow snorkel because the snorkel has been cleared of water.
Surface and Leaving Water – learn diving
When he came up fast localization of the vessel. Good to see, hear sounds propeller. Also check whether there are other divers who were still in the water.
By the time the diver was at the surface, but far from the ship, the divers can swim to the boat. Since the divers still use the complete diving equipment, the best possible way and not tiring is to fill the air to BC to reduce the load by using a snorkel and swim to the boat.
If you want to climb into the boat with ease, remove the weight belt and have a helper hold it. If the ship has stairs, then remove the fin and rose upward. If the use of a small boat, a diver who was in the boat must sit so as not to make the shaky ship.
Emergencies always possible on each dive, no matter how perfect preparation for it has been done. Quite a lot of variables that can be identified as a contributing factor. Diving conditions, panic, weather, depth, damage to equipment and so on. This situation if not immediately addressed secar a precise and fast potential to be the cause of the crash dive.
Ironically most of the dive accidents would occur when a diver was already feeling experienced (veteran), was quite capable of handling the problem dives. A situation that tends to make people become complacent and careless. Inattention and carelessness here includes both physical and mental. Inadvertence mental cause “human error”, or a human mistake when faced with a vulnerable condition can be fatal. Human error / mistake humane, that the main causes of accidents dives.
It is therefore recommended to remain relevant for divers senantiasabersedia train themselves, preparing, briefing, de-briefing, dive planning, check and re-check the equipment before the dive, relearn procedures are standard in learning diving and so on. Philosophy, better learn to recognize and avoid dangers before rather than after overcoming danger, because the results are very speculative.
Without state Air
Of the many emergencies that may occur whenever the dive, the situation “without air” is the most risky thing to overcome. For years people debating the street or what is the best way to do when faced with a state of “running out of air”. In fact, no one carapun that can be agreed as a way satisfactory and provide assurance of safety for the culprit. Unity Sport Diving Indonesia, offers several ways or procedures that are considered “feasible” to cope with such emergencies.
How to deal with emergencies divided into two categories, namely:
With the help of ”
An emergency dive with the aid divided into two, namely:
Octopus Assisted Ascent (OAA).
OAA can be done in terms of a learning diving provide air support to partners who run out of air, through the “extra second stage”, commonly called “octopus”. This method is relatively safe and easy implementation because each diver breathing through a “second stage” of its own.
Buddy Breathing (BB).
Done by alternating breathing through a “Second Stage” of the regulator of the helper (Donor). Should continue to be done while rising to the surface in a controlled manner, as it is often called BB buddy breathing ascent (BBA).
With the “Self-Reliance”
How to deal with emergencies that occur in learning diving, especially run out of air, may have to be done by divers, in which case there is no longer a partner who can be asked to help. There are two methods of “self-reliance” that could be done, namely:
Emergency Swimming Ascent (ESA)
This is how to deal with emergencies are independent, most importantly, where the diver ran out of air to swim to the surface in a controlled manner while continuously blowing air out, to guard against the development of lung excessive.
Buoyancy Ascent (BA)
Is a procedure “Self-Reliance” last option. Done by removing the weight belt and use positive buoyancy gained by developing BC in depth. Buoyancy ascent if the diver practiced seriously doubt that he might not be able to reach the surface by swimming. Buoyancy ascent from a depth is very dangerous because it is likely to surface movement rate becomes uncontrollable. Buoyancy ascent is often called the emergency / exhaling buoyancy ascent.
When the earnest face of emergency in the sense of running out of air, try to follow the procedure below through the top, namely:
Stop and think. Stop maneuver and reasonable thinking about the situation you are experiencing;
Exhale the air slowly (if they exist) and notice the SGP.
If the SGP still shows: -adanya air pressure, then press the drain; – No air pressure, check the cylinder valve, the valve may be the key still in the “off” position which usually occurs at the beginning of the dive.
Try to breath again when they air delivery, give cues on the partner and explain the situation. When the air pressure in the backup position, stop the dive and go up to the surface.
If there is no air delivery, ask partners to do OAA / BB. If the partner has been away, select maneuver ESA / EBA (as a last alternative).
If the partner can not take communication and do not understand the situation that face, then do ESA / EBA as a last alternative.
After all left the briefing did dives again about:
The goal has been achieved.
Obstacles and problems that occur.
The physical condition of the diver.
Damage to the equipment.
After all reached the place, the equipment must be cleaned and stored according to the procedure.
Familiarize divers make notes after completion of rehearsals, careful about:
The note was written on a drunk u that must be owned by each diver, commonly called “Diver Log Book”.
Cue in Diving
Cue is necessary to be able to communicate in the water or from water to the surface. Wide cues include hand signals, sight, sound, touch, etc. All cues can be used according to the conditions at that time.
Knowledge of cues in diving has the objective to facilitate communication between the diver so kegiatanbelajar diving will be successful, safe, and happy. It forged an agreement to communicate with partners before starting the dive.
The most simple and practical gestures are hand signals, for that every diver is advisable to know the meaning of the hand gestures. Thus, communication becomes easy in the water and the message can be delivered to the right.
