The survival ‘Rule of 3’ states that humans can go 3 minutes without air, 3 days without water and 3 weeks without food.
However, the brilliance of the human mind is such that we have created equipment that enables us to be continuously underwater for durations ranging from 30 minutes to even up to hours, and literally swim like a fish in the deep oceans.
SCUBA- a commonly used acronym that has come to become a word of its own, actually stands for Self Contained Underwater Breathing Apparatus.
A scuba diver’s gear is a piece of genius, designed for science, sport ergonomics and even aesthetics.
Enduring high underwater pressure, allowing for water resistance, being lightweight and compact for the diver to easily navigate with, and additionally give the diver the advantage to swim like a fish.
Scuba diving gear consists of;
The Buoyancy Control Device is an inflatable jacket that helps the diver stay buoyant while diving. It has an inflatable bladder connected to the air tank. The diver can inflate and deflate the bladder to maintain positive buoyancy at the surface and neutral buoyancy underwater.
The diver gets his/ her air supply for breathing through a regulator connecting the scuba tank to the diver’s mouth. A given set of scuba equipment has 2 breathing regulators, a primary source of air, and a back up known as Octo in case of lapse of the first one for the diver or his/her diving buddy.
Most divers use scuba tanks filled with simple filtered and dehumidified air, compressed into the tank. The standard volume of air for recreational divers is 200 bars, the use of which they can monitor at all times through the air gauge. Many advanced divers also use enriched air tanks (Nitrox) with higher composition of oxygen for better diving performance.
The scuba diving equipment list completes itself with a wetsuit that the diver wears to keep warm in cold underwater temperatures, a mask for the eyes to see underwater, and fins for better underwater movement.
Apart from the above pieces of scuba diving equipment, many divers use additional accessories like a dive computer to plan their dives by monitoring dive time, depth and other information, an underwater compass for navigation, surface markers to indicate the divers’ location to dive boats, knives for cutting oneself free in case of entanglement by fishing nets or weeds.
ScubaPro is one of the leading authorities of scuba diving equipment in the world. A full set of mid-ranged scuba equipment can cost from INR 70,000 to INR 1 lakh. Owing to the high cost and difficulty to carry around, most recreational divers prefer to rent out the equipment from dive shops they are diving with.
