I set my wing at the beginning of the dive on my initial descent. With a normal breath, I hold my BC hose over my head and let out the air continuously until the water just washes over my head. I immediately let go of the goesoutta button and drop the hose, exhale, and I will start to descend easily, albeit gently. If I need to descend faster, I go nose down and kick. If I have to breathe, I do, which stops my downward progress. I start my descent again when I exhale. I continue till I reach the bottom, inhale, and depending on how much thermal protection I am wearing, I might need to add a bit more air with the goesinta button, but it's never much. That's the last I'll probably touch my BCD until I ascend. Between ascent and descent, I only use my breathing to adjust my depth. A bigger breath will get me over a coral head, and a subsequent bigger exhale will get me back down again. A super inhale will start me toward the surface, and of course, exhaling will slow me down or stop my ascent altogether! At my safety stop, I'll usually breathe from the bottom of my lungs,
A few caveats:
TIming is crucial on the initial descent.
You'll figure out when to let go of that goesoutta button after a few times.
Never hold your breath!
KYGO!!! (Keep Your Glottis Open)
Use your chest muscles to pause your breathing cycle instead.
Relax and have fun!
Don't skip breathe!
Don't push it as it will come easily enough with continued practice.
Stay mostly flat
Except when descending and ascending.
Or to see a critter!!!
I can't tell you how many times I have laughed at people trying to get that last bubble out. 2 phreakin phunni! Learning how to breathe from the bottom of your lungs will help you avoid the Shake it Loose dance. There's also another, you're gonna slap your forehead when you figure this out, method to keeping the water out of your BC. Hold your BC valve upside down, but above the air in your BC. It'll act as a reverse p-trap for the air in your BC. Yeah, it's a bit slower, but if you need to let out that much air, over and over, you have a leaky goesinta valve. Unplug it and operate it manually instead, which is the way the good lord intended you to use it.
