Diving equipment – Lombok Diving
Therefore, differences in the environment, a diver will be faced with a new environment is water. It is necessary for the adjustment of the liquid, so it takes a particular type of equipment according to their use. Thus creating various tools to be able to adjust the liquid environment. Diving equipment is divided into two, basic scuba equipment and additional equipment.
Basic equipment Diving – Lombok Diving :
- Fins & Boots
- Buoyancy Vests
- Diving clothing / Wet Suit
- A weight belt / Weight Belt
- Diving knife
- Bags Diving / Gear Bag
Additional equipment – Lombok Diving :
- Scuba equipment
- Depth gauges (Depth Gauge)
- Hours Diving
- Antifog liquid
Masks – Lombok Diving
Vision in the water is very bad, it is necessary tool that masks. The tool provides an air cavity between the eyes and the water, so it will be more clear vision and can protect against water irritation to eyes. During the dive, the mask will have hydrostatic pressure. Therefore, the use of masks should not be too tight and always hold equalization (adjustment pressure) by blowing air into the mask through the nose, the nose should be incorporated into the mask. For this reason why goggles (goggles) can not be used for diving. Masks have weaknesses as a result of the combination of the angle of refraction and the index of refraction between air and glass and air which causes objects to be seen ¡¾2 times larger and ¡¾1 / 2 times closer. To get a good mask and in accordance with their use, need to pay attention to the characteristics of the mask as follows:
Tempered safety glass
The frame is made of stainless
Double seal / skirt is flexible to face
Nose pocket / pouch nose
Headband / dilengkapai strap with buckle
Judging Mask Types of materials:
Judging Mask Types of glass:
Selection of Mask – Lombok Diving
How to choose a good mask fit to face is to put on the face without using strapnya, air suction inside the nose slightly may then hold your breath, if the mask is stuck on the face, the mask is suitable for use. Choose tempered glass masks, small volume, wide field of vision, avoid existing mask exhaust valve.
Treatment Mask – Lombok Diving
Having used the dive rinse with fresh water that is clean and dry (avoid exposed to direct heat). After drying gave a talk (powder), and store in a cool place. Do not get depressed when storing.
Snorkel – Lombok diving
Snorkel is a pipe that used to breathe for divers in the water surface, useful for skin diving when resting on the surface. Through snorkel diver can breathe easier without having to hold your head out of the water while on the surface, so that it can freely observe the underwater situation. Pipe length ± 30 cm, if more it will grow large volumes of dead air space (dead air space) to reduce new air into the lungs paru.Snorkel usually hung on the left mask on dives, but can also be in front or the right, depending on the type of snorkel.Teknik breath by blowing air through the snorkel first, then exhaling, this is to avoid any water that goes through the end of the pipe that terbuka.Untuk know snorkel pipe end is above the surface, can be held in check with by the left hand. To know the end of the pipe has been entered into the water will usually sound water inlet pipe to snorkel on the left or right ear.
Judging Snorkel types of material:
Judging from the form:
Election Snorkel – Diving Lombok
Look snorkel inside the slick, to facilitate the blow so that no residual water left behind. Select a suitable and comfortable moutpiece mouth. The length between 12 s / d 14 inches.
Election Snorkel – Diving Lombok
Look snorkel inside the slick, to facilitate the blow so that no residual water left behind. Select a suitable and comfortable moutpiece mouth. The length between 12 s / d 14 inches.
Care Snorkel – Diving Lombok
Shaves diving, rinse with fresh water that is clean and dry and given a talk (powder) and stored in a cool place.
Fins – Diving Lombok
Use of Fins: Fins are used to increase the power pedal diver thereby increasing the flow of water, not for speed. Mechanical wear leg swing slowly but strong and relaxed. Fin is Indonesianized with the term “scuba flippers” or “frog legs” created to give strength to the legs and a device driver. Fins not made in order to increase swimming speed but increase the power pedal. With the help of fins swimming abilities we get 10 times more than without the use of fins.
Full Foot Style
Open Hill Style
Rocket / jet Fins
Open Tournamen Fins
Judging Fins types of material:
Choose fins that fit the size of the foot, not too tight and narrow, adjust the type of fins to the circumstances and needs:
Type Full Foot Style / Foot Pocket – Lombok Diving
Suitable for skin diving activities or swimming fins, usually more flexible, with more angled plate layout, which causes the legs do not get tired easily. Large-small size is a more decisive; more troublesome to wear and take it off for scuba diving activities.
Type Open Heel – Lombok Diving
Suitable for scuba diving activity, usually plated straight, semi-rigid slab longer. This type provides greater strength, but it takes time for the adjustment of the leg muscles. Open heel fins have advantages in terms of ease when putting on and take it off.
Adjustable Open Heel – Lombok Diving
This type is most suitable / appropriate for scuba diving in the waters because it is made to have a bag large enough to toe wearing boots (a kind of socks made of rubber), has a wider slab to generate a large and usually there are holes waterways at the top of the plate. This reduces the water flow hole leg fatigue caused by the negative area on a slab.
Treatment Fins – Diving Lombok
Similarly, masks and snorkels, finishes used wash with fresh water that is clean, dry and give the talk (powder).
Boots – Lombok Diving
Boots are boots worn during the dive. It is useful to avoid injury when the foot touches the bottom of the sea, coral, hard objects such as metal, etc. are also protective against seizures caused by cold feet and the possibility of foot blisters. Boots of foam rubber with hard soles feet is a type of protective equipment commonly used divers, socks commonly used divers, socks tebalpun can be used as a deterrent blisters during exercise. The use of the boot can also reduce injuries due to stingrays stingray barb while not able to prevent copy thorns.
Use together with fins. Boot is used first, and then wear fins.
Election Boots – Lombok Diving
Adjust the size of the fins will be used. Choose boots that have a strong composition which can protect the feet, so that injuries can be minimal. The thicker boots, the better. Should choose a boot that is not too tight so as to facilitate the circulation of the blood. To avoid slippage on the use of boots use powder before memakaiya.
Boots Care – Lombok Diving
Once used, the boots are washed with fresh water and then dry.
Buoyancy Vests – Lombok Diving
Buoyancy Vests use
This equipment is usually dipegunakan for emergencies but in diving activities are used to:
Floating on the surface of the water while swimming.
Resting on the water surface.
Rescue yourself and others.
Neutralization keterapungan in any depth.
Buoyancy Vest Type – Lombok Diving
Life Vest / Standard Safety Vest.
Bouyancy Compensator (BC)
Buoyancy Vest election – Lombok Diving
Choose in accordance with its requirements and match the body size, which is commonly used now on the kind of BC (bouyancy Compensator).
Buoyancy Vest care – Lombok Diving
After the dive, the vest may take in water, buoyancy vest to blow it and then turn downward to remove the water through the mouthpiece. Rinse with fresh water that is clean on the outside, and rinse with warm water on the inside. Dry with aerated, store in an air-filled.
Clothes Diving – Diving Lombok
Use of Clothes Diving
Slow the loss of body heat because of the warm water in wetsuits and skin as well as protecting the body from scratches corals and marine life sting.
Type Clothes Diving – Diving Lombok
Wet suit: clothing part can be wet by water, but blocking water circulation that exist between wetsuits and skin.
Dry suit: made of rubber and have air space between the outer and inner wetsuits which serves as an insulator.
Election Clothes Diving – Diving Lombok.
Choose wetsuits according to body size and needs while diving. In cold areas should wear a dry suit types, since it can make the body divers stay warm.
Protective clothing divers are now commonly used FOAM NEOPRENE WET SUIT, made of neoprene rubber which has bubbles valve. This material does not absorb water and are made in various sizes thickness of the material.
Clothes care Diving – Diving Lombok
For wetsuit, keep flexibility with no brush when washing clothes, pretty soaked with detergent. Dry with no direct sunlight.
A weight belt – Lombok Diving
Belt use ballast.
The human body will get upward buoyancy in the water at ± 6 pounds or more. Wet suits made of neoprene will add buoyancy greater than 5 to 25 pounds, then a diver to be able to easily get into the water need of ballast.
Belt type ballast – Lombok Diving
Weight Belt: Belt by weight of lead set according to the needs.
Weight Pack: Rarely used because it can not be removed in case of emergency
A weight belt Diving Lombok-election.
The easiest generally wear weight belt. If using 3/16 inch thick wet suit typically require lead weighing 10% of the body weight.
Weight belt must be equipped with QUICK RELEASE BUCKLE, namely a fastening buckle that can be removed quickly. How to use weight belt installed the latest and most first released, if in a pinch.
Diving knife – Lombok Diving
Is a versatile tool, used to help, digging, as well as gauges. Made of stainless metal, jagged, eyes and others may be useful to cut the rope in the water.
Diving knife mounted on the shank side in order to avoid snagging on the grass and so on. Posts SS.320 or SS.420 means SS.320 contains less carbon than SS.420.
Gloves – Lombok Diving
This equipment is in addition wetsuits. Useful to protect members of the body that is part of the hand from scratch hand and so on. Divers will be gently hand if submerged in water and when scratched very difficult to stop the bleeding.
Bags Diving / Gear Bag
Diving bag (Gear Bag), to save the submarine device that is not scattered, and to protect the equipment from the hot sun. Use a large bag that can carry scuba gear while on the move or in the boat. This bag must be strong and waterproof because the terrain is usually far and wet dives. Pilhlah diving bag that can carry fins, snorkels, masks, and bouyancy Compensator. Use the opening using metal type, avoid the use of a bag with a zipper.
SCUBA – Diving Lombok
Scuba stands for Self Contained Breathing Apparatus Under Water, which is a scuba gear that can be taken anywhere with divers certain time. Scuba became known in 1943, was introduced by a French Navy officer named Jacques Cousteau and an engineer is Emile Gagnan. The system known as Aqualung. Aqua means water and Lung is a lung.
Scuba gear according to the system work is divided into four systems:
1. Closed Circulation System
A system that uses acid / chemical pure oxygen absorber fitted to dispel carbon dioxide / CO2 out of the lungs. This unit is essentially throwing O2 blowing air back into the water. It is a completely closed system. This unit uses is limited to a depth of 33 feet. SCUBA use of this type of specific expertise required because it is very dangerous.
2. Open Circulation System
Demand Regulator and consists of compressed air tube (Compressed Air Tank) is a type of scuba tool that is currently the safest tool used. Compressed air is channeled through the regulator to the diver, and the air that has been sucked discharged directly into the water without further use.
3. Semi Closed Circulation System
Used for military operations and is a combination of open systems and closed circuit. This system has an air bag, box chemical, regulators and compressed air tube. This system allows the military divers to work in depth and long periods of time. This system requires a special heating and require specialized support equipment as well, until the unit is rarely used common.
4. System-Mixed Gas Circulation Closed
This system is very complicated, requiring special care and quite expensive. This unit has a breathing bag, a tool box and electronic chemical oxygen filter that can control the amount of O2 at a depth of over 1,000 feet, which provide enough air to go down and climb back to the surface for scientific jobs in its use requires highly specialized training.
Of the four systems discussed for sport diving is an open system.
Definition of Open Systems.
Open-air circulation means divers issued directly flushed out. This system greatly simplifies the supervisor who was on to find out the position of the diver to see air bubbles appear on the surface of the water.
Tube Scuba – Diving Lombok
Scuba tube designed specifically and in-test in order to accommodate the high pressure air. The air contained in the tube is not normal air filtered pure oxygen, which is usually inhaled air every day. Air is lighter than water, the effect can result in air-filled tube. A fully air-filled tube having a greater buoyancy than the tube that pressure has been reduced. It can feel when a scuba diver who completed the dives will be reduced because the air buoyancy tube has been reduced.
Tube for scuba diving on the material used is made of:
Steel (steel), of sizes: 38; 50; 71.2 cuft
Alluminium alloys, all size 38; 50; 71.2; 80 and 100 cuft.
The outer layer tube made of better steel galvanized to prevent rust, and then given a layer of vinyl or stained with paint. As for the tube made of aluminum do not require galvanizing because of the aluminum oxide itself, which is a protection.
For coating steel tube so that the moisture is maintained in order to avoid rust. As for the aluminum tubes are also prevented from moisture though coated with aluminum oxide. Perform a visual test every 1-year or 2 times to the tube that is often used at sea.
To know the tube is made of any material, from which the mill, the power of the air reservoir, the last hydrostatic test, etc., should be read fingerprints-sidiknya contained in the neck tube
Choosing Tube Scuba – Diving Lombok
Sports divers generally choose a single standard tube with a capacity of 80 cuft, for security buy a new tube removed.
Treatment Tube Scuba
Do not fill the tube exceeds the pressure permits.
Fill the tube with clean air.
After diving rinse with clean, fresh water. A large plastic basin filled with water about 2/3 of her are ideal for wash all the tools. Soaking time will release the salt dries and settles rather than just watering it.
Close the hole to avoid dirt.
Perform a visual inspection once every 1 year / more often, especially tubes that are often used in the sea. Occasional shoe tube removed for cleaning of dirt or rust formed.
Perform hydrostatic test every 5 years once the competent authority.
Protect against impact.
Do not use the tube until the air is completely discharged.
Long-term storage; fill with fresh air, put in an upright tube containing ± 500 psi rests on the shoe tube (tank boots) on the bottom of the tube.
Do not store in hot areas because it can increase the pressure tube.
Do not remove paint by burning.
Tube Filling Diving – Diving Lombok
For filling tubes each diver must be able to carry out charging. The trick is:
Connect the filling hose to the valve tube.
To open the faucet valve, wait until the pressure on the compressor over pressure tube.
Place the tube in a water bath.
At a certain time the water vapor discharge valve open.
Recommended charging less than the pressure permits.
The tube profiles are sold:
1. Steel Tube 71.2 cuft
Standard steel tubes with a length of 21 inches and a weight of ± 30 Lbs (when empty) and floating in the sea water. Compressed air into the tube maximum pressure of 2250 psi is approximately 60 cuft free air can be at capacity. When filled beyond the 10% that is 2475 psi, the free air that can be accommodated 71.2 cuft, commonly called standard immersion tube 71 cuft.
2. Aluminum Tubes 72 and 80 cuft, 3000 psi
Both the same length of this tube is 26 inches. For tube 72 cuft weighs 30 Lbs neutral in seawater while the tube 80 cuft weighs 33 lbs and is rather wide diameter of 7.25 inches. The second tube has a maximum pressure of 3000 psi.
3. Tubes 50 cuft 3000 psi.
The shorter tube is 19 inches in length, at a pressure of 3000 psi capacity 50 cuft while the 2475 psi pressure tubes containing 42 cuft free air. Neutral weighing empty and the air was reduced 3.5 Lbs when full.
4. Couple Dual Tube or more.
These tubes are used for divers workers, while for sportsmen do not wear it because it is too heavy, whereas consumption can be longer than a single.
Is one part of the tube, mounted on the neck tube diving, working as a tap is opened and closed as well as installing a regulator.
There are several forms of valve are:
1. Valve K / Non-Reserve
That is the simplest valve tube, has a hole for the entrance and exit of air. Closing or opening taps situated side. Tubes with valves requires divers to use additional tools to monitor how much air is still present in the tube. The tool is called “Submersible Pressure Gauge” or SPG.
2. Valve J / Constant Reserve
Is a valve which is similar to the type ± ¡° K¡, but had a mechanical valve reserves (reserve). Reserve works when pressure tube down ± 300 psi, it will automatically shut the spigot hole. By lowering the air up there is still a residual ± 500 psi. Valve reserves provide sufficient air to the diver immediately rise to the surface. Backup valve stem puller should always be in the up position (up position) even if the tube is empty, it is to loosen the valve spring in the reserve. Backup valve can easily be pulled down during the dive and this does not affect the supply air flow, only if the contents of the tube below 300 Psi will be no cessation of airflow.
Handling and Care
Avoid collisions because the valve is broken.
For valve ± ¡° K¡ when filling up down then fill up the rest of ± 500 psi.
Always check O¡ ± ¡° the rings.
When you open a valve, turn towards open until the end, then turn back towards the cap half a turn, it is to avoid congestion or damage to the cylinder valve. When would close the cylinder valve, do it subtly, but meeting and not have loud., Because most valves using nylon that can be damaged when forcibly closed and tight.
If you want to do a visual test, the tubes must be emptied slowly to avoid condensation around the valve and the neck of the tube when it is empty.
Never embellish any grease or lubricant on the valve. Workshop repair and maintenance using only silicone lubricating oil anti exploded.
To conduct visual test must release valve from the tube by means of a valve clamped with forceps (tangdem). Then the tube is rotated with the tools of rope or chain. When it is off check the state of the rings ± ¡° O¡.
O sealing ring (O ring)
Is a means of securing a leak between the regulator and valve connection, O-shaped rubber / silicone. Rubber O-ring (O-shaped rubber bands) are small located on the surface of the valve makes an impermeable high pressure between the valve regulator tube. Always carry a supply of O-ring in the bag diving equipment, because if the O-ring is missing then your regulator can not be used.
To prevent contamination entering through the air holes, made of smooth and resistant to corrosion.
Safety Plug / Safety Disc
Is a plug / small security plate shape. Mounted on the valve (the valve), will rupture if the pressure exceeds the maximum pressure tube. This is to avoid the tube burst. The location of the rear plate cylinder valve, prevents damage during air charging excessive or in case of fire. Examples of filling pressures that can damage the seat plate
1800 Psi will burst at a pressure of 2800 Psi
2250 Psi will burst at a pressure of 3400 Psi
3000 Psi will burst at a pressure of 3900 Psi
In certain circumstances plate (thin plate) can rupture at low pressure. This happens due to too fast charging or charging tube heat without soaking in water. These safety plates can be replaced on diving equipment repair workshop facilities
Persons Tubes (Back Pack)
Is a harness that attaches the tube system on the diver’s back. Many forms. But that is circulating now is BC that once joined packnya back, making it easy to attach the tube on its BC. Backpack and belt buckles disabled should have a quick launch in connective left shoulder belts. It is intended to facilitate the diver removing or replacing the tubes in the water. As with other diving equipment, diving cleaned after use with clean, fresh water, for BC rinsed with warm water on the inside, keep the air-filled condition.
The regulator is a device that is simple to change the high pressure air from a scuba tube into a low-pressure air in accordance with the needs of divers and only provide the necessary air according to the surrounding pressure.
There are several types of regulators:
Dual air pipe (Double Hose)
Demand regulator commonly known in the United States since 1949, consists of one section which is mounted above the cylinder valve with a breath of air distribution pipe, mouthpiece and an air exhaust pipe. At this time usually called Two Hose Regulator. Mouthpiece or Handheld Mouth is a part that is inserted into the mouth. This type of regulator usage is more difficult, because the diver must exhale loudly when going to breathe the air. Is generally used by commercial divers. Therefore, air bubbles are removed by divers out at the back of the diver, the bubbles do not interfere with the view of divers. The principle works has two levels, namely the first level (first stage) and second level (second stage). At the first level above the lowered air pressure around him and the second level air pressure is reduced as needed diver is in accordance with his surroundings. Remaining air coming from the mouthpiece will be returned to the first level to be dropped out.
Single air pipe (Single Hose)
Commonly used now is a single air pipe consists of two levels, namely the first level (first stage) and second level (second stage) are mounted on the mouth (mouthpiece). The air on the first tier ± 140 psi above the surrounding pressure. On the second level is reduced to the size of the required pressure. The main difference with the double hose is that the two separate levels. Where the Second Stage is located near the mouth of the diver to facilitate breathing, therefore, be a rubber septum on the same surface with the lungs in a normal swimming position. Single hose is also equipped with the drain (purge botton) which serves to throw the remaining water in the mouthpiece when it is pressed. To protect the first stage of the ingress of water and dust is also equipped with a cover (cup) mounted on the first stage if the regulator is not used. Both air and water can be expelled through the exhaust valve is made of rubber, which is located on the inside of the regulator. Aside from the amount of hose above, the regulator can also be distinguished by:
Balance First Stage
Unbalance First Stage
Balance is the first stage is able to adjust its output to the state of the contents of the tube that will change the pressure during use is ± 100 psi above atmospheric pressure mouth piece while the pressure tube will change from a few thousand to about 300 psi. There was also a kind of regulator is equipped with audio First Stage wheezes when the pressure is less than 350 psi tubing pressure above him, this gesture that the pressure tube approaching reserves. Voice sounds up to 60 feet away.
Regulators working system can be divided into:
Semi Closed Circuit
High Pressure estuary-SPG (Submersible Pressure Gauge)
To find out how the contents of the tube scuba air is to use a tool pressure gauge. In the first stage there is a common estuary marked with HP (high pressure). If the hose will be installed SPG SPG estuary associated with marked HP SPG is a benchmark tool that can carry divers located so that it will be able to always control the pressure tube used by divers. Generally, now coupled with a compass and depth meter (standard depth).
Low Pressure estuary
To attach the hose connected to the mouth piece it is linked to the mouth of the low pressure hose and regulator can also be paired octopus and inflator hoses for BC.
Assemble Regulator on Tube
To attach the regulator to the cylinder valve is no installation technique that is in the following order:
Open faucet valve slightly. This is done because there is the possibility of dust and dirt in the valve hole can be detached / pushed out.
Replace the regulator on the valve, before the control valve O-ring and place on yokenya.
Put always pipeline regulator to the right past the diver’s right shoulder.
Before opening, the suction through the mouthpiece to control both, and whether or not the regulator.
Open air valve faucet until the end and then return the faucet half a lap. This is to avoid congestion / damage to the valves open and close. When opening the tap point SPG to a safe place.
Trying to breathe through the mouth piece 2/3 times the suction.
Refer SPG, check the air pressure in the tube.
Removing the Regulator
After the dive, to release regulator that is still connected to the tube then that should be done is the opposite of the installation, namely:
Let the water drip to dry first before the valve is opened.
Close the faucet valves, closures do not hard, just naturally.
Exhaust gas left in the hose by pressing a button on a single hose kurasnya or by blowing air out the rest of the Two hose. If the regulator removed without removing the residual air, it can result in a jolt to the O-ring which sometimes resulted in O-ring is broken.
Open regulator of the cylinder valve, control valve O ring.
Replace the cover (cup) to avoid dirt and dust.
Shaves for diving regulator should be treated with care. Chlorine from water swimming pool or in the sea can damage the regulator if not washed with fresh water that is clean, that is the way while allowing the scuba regulator mounted on the tube with compressed air in it. Rinse with clean warm water. If this method is not possible, the second way is by putting the second stage under the tap water and rinse. Do not press the botton purge (drain button) because it can lead to the entry of water into the first stage. Drain before storage, the hose should not be bent storage time, place in a special place and a cool and dry, keep it away from the pile that can damage the regulator hose and mouth piece.
Pressure gauge used to check the pressure tubes that will be used. Use of this tool is more efficient, because it does not need to check each tube with SPG and for checking the finished tube back pressure is used in order to sort out the tube that is still usable and which has little content.
Depth gauges (Depth Gauge)
To be able to determine the depth of the current dive, we need a tool that is Depth gauge / Depth meter. This is very important in the use of diving tables. Depth benchmark is comprised of:
Capillary rod works on the principle of law boyle, consists of a glass pipe closed one end, the existing air in the capillaries will change when the pressure is changed, then the volume of water that is in this capillary tube size will be the size of the depth. These benchmarks can be read with great accuracy up to 80 feet.
Benchmark Bourdan Open
This criterion there is a hole in the side of his house. The water is pressed into the through hole bourdan it causes changes in the shape and mechanically bourdan forwarded to the needle pointing depth. Used at a depth of 150-200 feet.
Bourdan benchmarks Closed
This criterion is not open to the water around him, his home are closed there is oil. The water pressure around forwarded through flexible walls to bourdan. Bourdan shape changes because the pressure is transmitted to the needle pointing depth.
This benchmark consists of a toothed wheel mechanism in a sealed room, the pressure changes will cause a deflection of the metal diaphragm. This deflection of moving gears and this movement is transmitted to the needle pointing depth. This criterion is very meticulous. Sometimes combined with capillary benchmarks for shallow depths and standard diaphragm for depth inside.
Compass usually has united with the regulator and part SPG. Compass in the water is very functional, especially on sandy area where the divers difficult to determine the direction. GPS (Global Positioning System) is usually used for night diving (night dive) or dive deep and long because it is difficult to determine the direction in darkness.
Flashlights are used for night diving, as a marker, and the cave dives.
If diving is done in the evening or on a less friendly weather prepare a flashlight.
In dives each diver must carry clock or other timing device. It is to know the times of the dives. Hours during besides can see the time, there are also combined with depth meter and compass. This makes it easier dives. Note boundary water resistant. For dives that do not exceed 7 meters may be used clock that has a water resistant 10 bar (eg, Q & Q).
Beauty under the sea is very beautiful make divers want to capture precious moments in both dives with photos and video. During taking pictures consider the surrounding circumstances and the position of the body in order to secure the dives.
Functions to store valuables or means of communication that is not possible in live during penyelaman.Sebelum use check whether the bag is leaking or not. Note the color of the bag, which is too shiny colors will attract the fish that might cause harm.
At the time of diving or snorkeling, sometimes we wear masks fogged / misty, consequently obstructed view becomes blurred because of dew. The dew generation due to airflow (warm) from the lungs through the nose, while the environment (water) surrounding the lower temperature / cold. At the time of the dive, we are accustomed to breathe through the mouth. Therefore, berembunnya mask (because breath through the nose) when diving is reasonable, because at the moment we are accustomed to on land breathe through the nose. Dewy mask is actually not a big problem, because every diver course taught how to mask-clearing in the water. However, if too often dewy and mask-clearing, then the air in the tube a lot of wasted so quickly exhausted, but it dives into uncomfortable. To prevent the appearance of dew during the diving / snorkeling, the easiest way would use liquid anti-foging before we fell into the water.
Anti-foging fluid can be easily found in stores that sell scuba gear. About the price of cheap or expensive, is relative. However, actually in the bathroom we are anti-foging more cheap to prevent condensation on the mask that we wear, that is by using toothpaste (any brand). The trick, said toothpaste smeared on the inside and outside of the lens mask. Once leveled, then rinsed thoroughly, the mask is ready to use. However, if at the time of going down but forgot to bring toothpaste, friends do not need to worry, because in our mouth there is an anti-foging that we always carry it everywhere. Anti-natural foging is saliva saliva alias. Enough to use it with saliva ± ¡° menyemprotkan¡ us on both sides of the mask. Flatten, then rinse thoroughly (the look and aroma). Then the mask is ready to use and will be comfortable dives
