First off, it was fun as heck. No one even batted an eye at the vintage gear I brought, and the PRAM performed fine for the first two dives. During the third one, it was breathing harder and wet. When I surfaced, the top can was rotated. I pulled off the band clamp, and the mechanism was wet, so the diaphragm had not stayed compressed. I tightened the band clamp down, but couldn't get the can to stay in place, so I started swapping my hoses onto my Conshelf XIV to finish the day. That's when I noticed that the HP hose for my gauge had split. Of course, I had brought extras of everything else EXCEPT another pressure gauge. No one had a spare pressure gauge to fit, so I borrowed a Scuba Pro reg from one of the instructors to finish out the trip.
All in all, a fun trip, though. My main dive buddy was a gentlemen who was very interested in vintage gear. He has a double hose reg at home which he would like to get rebuilt, so we may have a new forum member soon. The water temperature went from the mid to high 50s on the surface to low 40s under the thermoclines, with 70 feet pretty chilly even in a drysuit. The visibility was ok(or downright amazing when compared against Kansas lakes). Once they got the dock fill station up and running, you could surface, top off the tank and be back in the water within minutes.
Finally, I can say that the crew from Pro Ski & Scuba are an excellent group. It was a nice and relaxed atmosphere, and everyone there was ready to lend a hand at any time.
