Scuba Gear

Scuba gear serves as a major part of any diving experience, regardless of the particular location or purpose for diving. As a matter of fact, the equipment worn and used can make a difference between the feeling of comfort and discomfort, success and failure, and safety and danger. Aside from the very important knowledge regarding underwater dynamics and the physics of pressure and compression, the gear a diver uses is the most important implementation necessary for any and every single diving run, whatever it may be. Of course, the location, depth, and purpose of a dive determine which particular type of equipment is needed, as not every piece of scuba equipment is appropriate for every dive. For beginners in shallow water, a set of goggles or a mask, snorkel, and flippers are all that’s necessary; for deeper dives, such as wreck expeditions or cave explorations, require more elaborate equipment, such as a wet suit, skin, helmet, decompression vest (BCD), and definitely an air tank are essential. The time of day makes a difference, too, as a flashlight will be necessary at night, regardless of the depth of the water, and not during the day in shallow water.

Among the most important pieces of scuba diving equipment available are: scuba regulators, which assist divers in moderating their breathing; dive computers (technological developments that provide convenience and accuracy especially during deep and really involved dives); scuba masks, some of which cover the entire face, or, like goggles, simple giver the eyes when a snorkel is used; helmets, which are necessary in deep, dangerous waters; underwater cameras, especially for commercial and research dives; scuba boots or booties, some metal, others made of flexible material; scuba fins and flippers for easier navigation through water currents; scuba tanks (or O2 tanks), which can be heavy and uncomfortable, but are necessary for deep, long dives; Decompression vests (BCDs), which protect divers from the gradually increasing pressure of extreme depths; gauges for monitoring personal settings; dive suits (wet suits, dry suits, and exothermal jackets), designed for comfort, navigation, camouflage, and temperature regulation; scuba weights to accommodate buoyancy; utility belts for carrying extra accessories, such as knives, flashlights, and guidelines; and waterproof watches, some with built-in lights, for monitoring time while underwater. This last one is essential for those on deep, long dives where timing underwater is crucial to well being.

All dives also require some form of dive table to record dive plans, location, duration, the type and purpose of dive, gas mixture, and compression profile. These must always be completed before the dive and never taken with the diver underwater. Should some danger occur, or a diver wind up missing, these records are used to assist search parties in their mission to find and retrieve the diver in question or to investigate accidents.

Gear for scuba diving is or can be used on a mix-and-match or optional basis, but knowing what is necessary will allow divers to acquire the important equipment necessary for safe and successful dives.
