–iPhone SE lost 20% of charge in roughly 24 hours (8:30 AM 6/9 to 10:00 AM 6/10).
–Played with regulators a lot. Found out Tekna/Ocean Edge IS adjustable, after you pull the knob off. Guessing there’s a built-in real-time adjuster on non-octopus models (if they exist). Reg is really flimsy: two screws hold the exhaust piece on, and the plastic threads had broken off one, so it was useless. Might have to buy the eBay Ocean Edge–the design does breathe easy.
–Compression ferrules came in. Buttoned everything up tight, still leaks like crazy. Crap. Back to o-rings I suppose.
