Hi, I recently started having problems with my MR12 Proton.
I had the reg serviced in April at the Mares dealer that I purchased the reg from. When I got it back it was working ok except it was free flowing. I took it back and had them adjust it some so that it would no longer Free Flow.
About 2 weeks later I began having problems with the First Stage. It began making a loud screeching noise anytime I do anything that requires it to give me air. If I purge my regs, use my Octo, use my inflater, anything, it screeches at me. Since the shop I originally purchased it from is a 3 hour drive away, I took it to my LDS to have it serviced. My LDS determined that the 1st and 2nd stage needed to be rebuilt because the shop I originally purchased it from apparently had never done so. At this point I believe the issue was resolved.
When I picked up the reg from my LDS, I checked it on one of the tanks, it breathed great, no screeching noises at all. That night, when I got in the pool to assist with a class, it almost immediately began screeching as soon as it got wet. It is an extremely loud screech that is coming from the 1st stage. (We have confirmed this out of the water). The Techs at my LDS are not sure what could be causing the problem, and I am quickly getting fed up with this reg.
It is 3.5 years old at this point and Up until now I have never had any problems with it. After reading through the forums I have noticed that this seams to be a common problem with Mares 1st Stages. Does anybody have any advice on what the problem could be that I could pass along to the Techs at my LDS to hopefully resolve this issue? I will be starting my DM Internship next week and really dont want to have to listen to nails on a chalkboard on every dive.
Thanks
