BP2 Reviews/Specs

Disadvantage is that it cannot be completely environmentally sealed which is a concern with saltwater diving.

It has a cold water kit to seal it. Does not not count or is it still partially open when the kit is installed?

It depends on what the cold water kit actually does (no answer yet). The ambient chamber could be packed with silicone grease. In some cases if packing is not done properly there could be small spaces where seawater could actually collect and do more harm.

Actually I own some Apeks regs and a HOG D1 cold (obviously all diaphragm regs). I am quite satisfied with the D1 but it is not yet due for service so I haven't seen the insides aside from the 2nd stage air barrel assembly. I was thinking of getting the BP2 but was concerned about the chroming of the body and the piston (if it is indeed chromed brass and not SS). I had some crusting/corrosion with the 2nd stage adjuster knob where the decal attaches to it after <10 dives in saltwater. It is not a critical part so I guess it's OK. I was just wondering what will happen if it happens to the piston or the inside of the body which constantly see saltwater.

The first HOG reg I purchases did this, I removed the sticker cleaned it and all is good. I now have seven HOG seconds with no stickers on the adjustment knobs.

I also removed the stickers.....salt water got trapped and left nasty crystal deposits.

I try to buy/use only diaphragm regulators. I have done this since I got my first MR-12s back in the sixties. With a diaphragm reg you may sacrifice a tiny bit of "ultimate performance" on the first dive you make with the reg, in return for much better and consistent performance from the second dive on. Diaphragms keep the moving parts dry.

Just in case I usually add any sort of cold kit that I can to the diaphragm regulator as a second barrier to salt water.

Hopefully, Chris will chime in at some point. I PM'd him and asked this very question. With the cold water kit, the chamber is completely sealed against water.

not silicone grease please, tribo or cristolube.

Isn't christolube more water soluble? Won't it run in warm (tropical) weather? Or would I be better off to just rinse the regs thoroughly? And at the current price of O2 compatible grease (21 USD for 25g - retail) here it might significantly affect the price of the reg considering that you might have to re-pack it mid-service cycle.

honestly I would just rinse them well if I was still living in the tropics. In fact my personal BP2 don't have the cold kit installed.
