Hmm, I guess I need some dem square thangs.
Luis, I am sure it is just a matter of getting them in the water so I can see what the state of tune is and then I will have a better idea of how much venturi effect is needed, if any, and play with the IP a bit more. I have my second HPR installed now in my Navy Phoenix which is a second gen unit and always a superb performer. See, I had a stainless steel vane and a urethane seat in these units and an IP of about 145ish. Going higher on IP always resulted in a jumpy regulator that wanted to free flow at depth.
I am headed back to the pool today, hopefully after my swim I can get them in the water, Sunday is bad for that though at the Y. My first dives are Monday week and will be a beach dive out to the Pompano Drop Off, solo, a good half mile to mile surface swim out, I will use my faithful square label Royal. This is pretty shallow, max depth about 60 to 70 feet. I probably will wait until I get down to Key largo a few days later. There, going out with Ocean Divers, always a blast, the diving will be shallow so an excellent opportunity to get a real feel for the HPR without being so deep that a "required" ascent would be an issue. When I am carrying my camera, which is most of the time, I like for my regulators to be transparent so I can focus on the dive and not leaving bits of expensive camera gear on the sea bottom as I am want to do.
I got my round label, 006, set without venturi assist. The Navy has one bleed port blocked with the barrel washer. Should give a good feel for the difference and help me learn a direction to go in. These HPRs are very exciting!
