The most important element for divers is their regulator. There are several types of diving regulator, depending on the intended use, such as piston or diaphragm regulators, designed for use with AIR, NITROX, OXYGEN or mixtures of these.
The choice of regulator will depend on the type of dive, the gas being breathed and, above all, the performance expected at depth, which should not be overlooked. Based on experience, it's best to buy a regulator that will deliver a high flow rate when you need it.
The best-priced regulator packs come with accessories such as an octopus, pressure gauge or console, depending on use.
