My dives have been getting longer. Not by a huge amount but enough that the need to pee towards the tail end of the dive is starting to get more urgent and more uncomfortable. I've already gotten dehydration headaches a few times on dive days and I'm now chugging water pretty much all day, starting during the drive down. And with a move to diving double tanks imminent, a P-valve was a no-brainer.

The good news was that the P-valve worked perfectly - it's well worth the extra steps needed to use it. The bad news was that I had a slow but persistent neck seal leak. I found a small nick which was probably exacerbated by me trying to gear up a lot quicker than I should have.
