Scuba diving is an equipment-intensive sport because humans are not designed to swim, or stay warm underwater. In this sport, we rely on gears for a successful dive. Here is a handy guide to the essential gears all scuba divers need:
So you can see clearly underwater, your dive mask makes a pocket of air in front of your eyes and nose—which also equalizes the pressure on your ears and sinuses as you dive deeper. Snorkels are breathing tubes that enables you to inhale and exhale when swimming face down near the surface of the water.
You breathing apparatus underwater—connected to your tank and delivers air to your mouth when you inhale. The one with a neon-bright yellow body with longer hose is called an octopus—it is a backup regulator.
The BC or buoyancy compensator fits like a backpack. It supports the weight of your tank above water. The BC’s most significant function is to help you control your position in the water. You rise toward the surface by adding air to an internal bladder; you sink toward the bottom by venting air from it. Found at the end of the corrugated hose on the left side is part of the power inflator.
Dive computers monitor and display your depth, time underwater and how much longer you can safely stay. They can also keep track of how much air you still have left in some models.
Diving fins give you powerful kicks underwater. For bare feet, use full-foot fins; wear neoprene booties for open-heel or adjustable fins. Perfect fit is the key to finding the right fins.
Wetsuits provide insulation—to slow down cooling effect when underwater. Common thickness options: 3mm-thick suits in full and shorty (bare arms and legs), full-length 5mm, and 7mm full-suits with a hood and gloves.
