2.5 years ago I rebuilt a Scubapro MK10 and the IP was 130 psi with no shims. After about 30 dives the IP is now around 100 psi. Does this mean my spring is going bad? Should I shim it back up to a higher IP when I rebuild it? BTW - it still breathes great on the G250 2nd stage.

Can anyone tell me about their experience at Sea Camp in Big Pine Key, FL? i am considering sending my 13 year old son there for a week, but I've read mixed reviews about it. My son is a new SCUBA diver, but also into sailing, surfing, and just about anything related to the ocean. Any insight...

Does anyone know why the dive industry uses 40% as the nitrox threashold? It seems that both certification agencies and equipment manufacturers cite this number most often.

Do all or most Atomic regulators use the same service Kit? If I get a B2 will I still be able to get a rebuild 20 years from now?I'm thinking about a new regulator, and I want something that will last as long as my current (and still functioning perfectly) SP MK10/G250.

What is the most common point of failure for regulators? I'm not asking about regulators that have been subject to severe neglect, but ordinary use with basic maintenance. If you could double the useful life of one component of either the first or second stage, which one would you pick and...

In the summer of 1996 I purchased a Zeagle Ranger BC. I've used it on hundreds of dives in several different countries since then. It has always been comfortable, perfectly balanced, and trouble free. Last month I noticed that the threads on the bladder fabric started to fray where the dump...
