my G250/ Mk25 and Nighthawk BCD are 19 years old with few issues (the BCD has faded to a dark brown). I have buddies with much newer gear running into issues. How good is there new stuff? I don’t know, I haven’t needed any of it yet…unpopular opinion, scubapro is overrated and overpriced. though for that sale price might be worth it

The good news? it’s my gear…. I’m not the type to geek out over fractional differences in performance. If I were going to take it in caves or under ice, I may become more concerned about some of the specs, but I’m not going beyond 120’ or below 50F.Please let @rsingler know. He hates SP's MK25's

I drilled out the ambient holes on two of my MK5’s to make them easier to rinse since I will never pack them with silicone.Some SP piston first stages have such tiny ambient holes they are difficult to flush. I like the Mark V and Mark 25 bodies that have the large vent holes making flushing easier. I updated my NIB Mark 20 with the service bulletin and added the Mark 25 conversion to it but it still has the tiny ambient vents. I need a more recent M25 barrel to alleviate that issue.

One other MK5 is a generation behind the tiny hole style and has big holes, and two other MK5’s I have not touched yet.
