Mares has a launched what they hope will become the new benchmark for cold water regulators; the Fusion 52X.
Traditionally Mares regs have a bypass tube, and this is also the case with the Fusion. The thinking behind it is that a significant amount of gas is delivered into the second stage, improving the quality of the breathe, whilst reducing the chance of freeflow.
Mares state when they designed the Fusion they increased the bore and changed the angle of the bypass tube, thus the gas flows smoother when compared with previous models. The 52X comes with 2 HP and 4LP ports and has a new seat design, hence ‘X’. As this X seat has great longevity, Mares has increased the recommended service period to 24 months on this high performance, balanced diaphragm regulator.
