Mares Fusion 52x (SRP: £483)
The Fusion 52x is a good-looking regulator that has some notable design features.
The first stage is solid but compact, equipped with two high-pressure ports and four low-pressure ports, and thanks to ACT (Advanced Coating Technology) has massively increased durability. The all-metal second stage has a unique pivoting purge valve, lightweight Superflex hose, and a neat ‘twist’ control to boost the flow rate from natural breathing to power breathing.
Mares have always turned out great regulators, which previously were just set up to breathe well out of the box and didn’t have any diver-adjustable controls. That all changes with the Fusion, which boasts a neat ‘twist action’ over the hose to set the delivery rate of the gas – it is not hard to see that the designer was maybe in- uenced by motorcycles! Didn’t notice a huge di erence with this control, but everyone liked the huge purge, which pivots rather than presses fully inwards and was very e cient. Smooth breathe in all positions, and sur- prisingly lightweight for an all-metal reg.
