Although diving is not a particularly difficult task, it is still dangerous for unskilled divers, in addition to bringing some physical diseases such as sunburn, deafness, pulmonary edema, etc. It also may cause to lose lives.
Therefore, it is necessary for divers to make adequate preparations. as a diver. Here are six essential scuba diving gears that you must bring unless you don't want to go back ever.
1. Buoyancy Control Device (BCD)
A Buoyancy Control Device (BCD) is a device that provides scuba divers with buoyancy control during scuba diving. It is essentially a inflatable vest/jacket worn by a diver with air pockets. The more air you add to this inflatable bladder, the more buoyant you will be. Conversely, when the air is released from the bladder, you will be less buoyant. Add air through the inflation valve. Air is exhausted through the bleed valve.
Why is the BCD(buoyancy control device) so important for divers?
When you are negatively buoyant, the downward pressure of you and your equipment is greater than the upward pressure of the water, in which case you’ll sink.
So, bring the BCD when diving, it will save your life.
2. Diving Mask
A diving mask is an item of diving equipment that allows underwater divers, including scuba divers, free-divers, and snorkelers, to see clearly underwater. Surface supplied divers usually use a full face mask or diving helmet, but in some systems the half mask may be used.
Although the diving masks seem to be little more than goggles, they are in fact essential to proper safety underwater.
How to choose the right scuba diving mask?
- Choose those safety lenses made of tempered glass, which can effectively resist breakage and scratches, which makes diving safer.
- Choose the right size mask. The mask must fit your face properly in order to be properly waterproof and protect your eyes.
- The mask straps can be made of silicone, neoprene or rubber. Generally, silicone and rubber straps are suitable for cold water diving. For those diving in warm water, neoprene straps are the best choice.
- The nose pockets of the mask should not feel tight and should fit snugly against your nose, allowing for easier breathing.
Most divers still prefer to wear a full wetsuit—usually 1 to 3mm—in order to cover their skin and protect from brushing against harmful corals or stinging marine creatures.
What the differences of between wetsuit and dry suit?
Wetsuits compress with depth and lose some of their inherent buoyancy. Dry suits allow the diver to add air and compensate for the increased pressure at depth. As the wetsuit compresses, it gets thinner and loses insulating capacity. The dry suit does not.
Diving masks are very easy to fog up during diving, which is not only unfavorable for diving, but also brings certain safety hazards. Then, defogging equipment is very necessary to carry.
Many divers carry a bottle of watered-down baby shampoo with their dive gear. A few drops rubbed into the lens and then briefly rinsed out keeps a mask from fogging. Baby shampoo is preferable to standard shampoo, as it is generally hypo-allergenic, less irritating to your eyes, and biodegradable.
5. Dive bootieswith fins
Why do divers need fins and booties?
Booties can keep your feet protected from sharp objects such as shells, rocks, and corals. Not only does owning fins prevent injuries and ensure long, memorable dives, it saves money in the long run by eliminating rental fees.
6. Scuba tank
A scuba tank is a gas cylinder used to store and move high pressure breathing gas needed by a diver.
As we all know, the oxygen tanks are filled with oxygen. This diver will not dive into the deep sea and suffocate due to lack of oxygen. Well, do you know how much oxygen is in it?
While it is true that the air in the tank is partly comprised of oxygen, it is not usually more than is naturally occurring in the air we all breathe, which is about 21%. The majority of that air is nitrogen, coming in at about 78%, and the remainder is a mix of argon, carbon dioxide, neon, and helium.
These small scuba diving gears must be prepared before departure. As for how expensive to buy, all depends on your own needs. The right one is the best.
