  • Description

    The Atomic B2 Regulator uses the same first and second stage designs and features that are found in the T3 regulator for unbelievable performance but differs in the materials used in the first stage to make it a more affordable option for divers that still want the best.

    Rather than being made from Titanium and other exotic metals, the B2 first stage uses chrome plated marine brass and stainless steel to lower the overall cost of the regulator. The design and performance doesn't alter with its high performance flow-through balanced piston design and swivelling low pressure turret.

    The second stage on differs cosmetically from the T3 second stage as it utilises the same titanium valve construction for a lighter and more durable regulator. The second stage features diver adjustable inhalation control for a customised breathe and asn automatically adjusting venturi vane rather than a manual control. The B2 is fitted is a stainless steel ball style swivelling joint for a more comfortable fit to the mouth

    You can now customise your second stage with the Atomic Colour Kit!
