On a recent dive, I was able to lay my hands on this beaut. This was the first times I had used a Mares reg., though the companies excellent reputation gave me a good feeling about it. The MR22 Diaphragm First stage features the DFC (Dynamic Flow Control) system and a replaceable HP seat connector. The HP seat is designed for a 2 year/200 dive service interval; double the standard seat life! The Abyss Second stage with its Vortex Assisted Design system is made of nickel and chrome plated Brass This offers a number of benefits: ruggedness, thinner walls, reduced water drag. There is also a good anti freeze function which is enhanced by the radiator action of the metal, allowing for use in more extreme conditions. Breathing at all levels was easy, with the air coming out in at a good volume and without serious demand. My one gripe is with the mouthpiece itself, in that it was slightly too small, though this is easily remedied with a personalised change. All in all, a pleasure to use, which should last years due to its solid build.

I'm a fair weather diver (i.e. only on holiday in warm waters) so I haven't bothered buying a regulator, although I have everything else. Mares do have a good reputation, although a wetsuit I bought of theirs split on my first holiday.
