Hi all,
I'm new to posting on the board but have lurked for quite a while. I live on, and dive in the big old St.Lawrence river on the NY Canadian boarder. I've had my open water since 2004 and am just getting back into diving after about 7 yrs off (cpl kids and jobs) and would like to get my nitrox card. I just completed my wait for the huge number....21st dive!!!! and have run into a hitch with my 2nd stage.
I use a Mares MR22 abyss (as do both my partners) I really like the reg and had it overhauled in June.
Coming back to diving caused me to do a lot of reading on it, and I decided I wanted the 40 inch miflex hose routed under my arm to a 90 degree XS scuba fitting for the 2nd. I got the 1/2 to 3/8 adapter and put it on. I realize the dfc is supposedly meant for the other hose for the best flow, but most companies use 3/8 so I thought I would give it a try. The reg worked fine I dove it 6 times and it breathed just like normal and like my buddies, not that we are really pushing them at all anyways.
So, on my last dive I turned on my tank and heard kind of a little honk from the 2nd, then I breathed it and it felt different, harder to get a good breath, until you really sucked then you would get full blast. I breathed it for a minute or so and it seemed better so I dove it. Knowing my octo was working good I used the 2nd and monitored it, and it was different than before. After the dive I compared it to the other Abyss on site and mine was harder to crack, and had noticeable free play in the diaphram. the purge was also weak.
I got it to the shop and just like I thought would happen... I was basically accused of opening it up and messing with it. The tech said the adjustments were changed from where he set it, cause he logs the adjustments. I agreed with him that it was not the same but NO ONE opened the reg I can assure you I have enough hobbies to keep me busy, I dont want to learn how to tinker with my reg adjustments and drown myself!! He said the different hose and angle fitting were causing a bunch of hard breathing as well as the altered adjustment. which I disagreed with because I used it, and it was fine before the noise.
My questions are... can a 2nd stage come out of adjustment that quick on its own?
Could the different hose size and fitting cause some weird pressure or flow issue with the dfc port, and cause it to go out of tune?
thanks.
