Good afternoon gentlemen,
After having rebuilt my DA Aqua master using the Cyclone first stage and HPR second stage, I was able to take it to the quarry today. I thought I had it tuned properly, but breathing was somewhat difficult. The IP is set to 135, but not having the proper gauges to measure the cracking pressure, is there a trick/bench test way to set the second stage cracking pressure, other than trial and error? Otherwise, it performed flawless, thanks for having the parts to rebuild this unit.
Thought from a total novice. I haven't even been diving with a DH regulator.
People are use to wearing back packs (for camping, hiking, etc). They feel right when they ride up high on the back. So when we put on SCUBA tanks we naturally look for the same feel. We also don't like the tank riding so low that it hits our legs. I have see suggestions on the forum to wear as small a tank as you can for the particular dive. Good advise. With a SH regulator we can get away with riding the pack as high as we can with out it putting a crator in to the back of our heads. So basically the comment is it doesn't feel right with the DH regulator properly placed on the back. I realize I am stating the obvious to this group.
But, maybe the feel needs to be pointed out to us newbees.
I Hope this was of some value.
