Atomic Aquatics B2 (SRP: £591)
Atomic Aquatics have a long legacy in producing high-end regulators, and the B2 combines much of that knowledge and technology.
The first stage is made from chrome-plated brass and 316 stainless steel, has two high- and five low-pressure ports, and features Atomic’s Jet Seat high-flow piston design, environmentally sealed for cold-water use.
The all-titanium second stage features Atomic’s Automatic Flow Control (AFC), rapid adjustment knob for manually detuning the second stage in special situations, and a polished 316 stainless steel comfort swivel. As with all Atomic products, the reg benefits from a limited lifetime warranty – not contingent on proof of service – and boasts a two-year/300 dive service interval.
The B2 has quite understated looks, and to be honest, with the all-plastic outer body, doesn’t look like a ‘pricey’ reg. However, it is well built, and the performance is up there with the best in this bunch. The control knob doesn’t make a huge difference to the performance, but it breathes well, the mouthpiece is comfortable, and everyone liked the comfort swivel.
