Edit: ideally wifi cameras that I can solar power.
Looking to replace my Arlo cameras with something self-hostable. Arlo lets you store on a USB stick, but there's no way to get out from under their cloud, which gets more expensive all the time.
Pretty new diver here, about 40 dives, and looking for advice.
Just finished up a week of dives in Grenada, and made a point of paying attention to air consumption. Based on Internet advice, I focused on breathing deeply and exhaling completely, counting 4 seconds in, 6 seconds out. Doing this, my computer reported average SAC has dropped from about 0.8 to 0.5, and I'm not the one calling dives for gas anymore. This seems like a great improvement.
However, my buoyancy goes to shit when I'm doing this. Breathing more "normally", I can maintain a neutral depth with good trim. But with this more efficient breath control, I go up and down several feet with every breath. This actually makes it pretty easy to control when I ascend and descend, but obviously isn't great for most of the dive.
If I try to breathe normally-but-slow, I feel like I'm hyperventilating.
So what's the trick here? How do you both breathe efficiently and control your buoyancy?
I think I'm pretty well weighted, since I have no problem maintaining my safety stop with the shallower breaths.
