The regulator reduces air pressure to make it easier to inhale. This equipment is classified into two types: the piston version and the diaphragm model. The piston regulator contains two groups too: the simple piston and the compensated piston.
The wetsuit protects the diver from cold and injury. Manufactures uses neoprene, this material provides good thermal insulation.
The mask protects diver’s eyes and lets him enjoy the view. Full-face mask have one piece or double lenses.
Diving fins make it easier to move around underwater. There are two categories of fins: full-foot fins and open-heel fins.
Diving stabilizer waistcoat

Very cold water requires a diaphragm regulator. The regulator system (Din or int) depends on block and pressure. The DIN system is suitable for a maximum block pressure of 300 bar. The INT system improves watertightness, but the diver must be very careful when handling.
Adapters are available to simplify selection. Brands specify the regulator’s suitability for cold or warm water. They also add some feature. Anti-freezing is designed for cold water. Venturi effect simplifies inspiration at great depths. After the technical criteria, take the time to test mouth comfort.
