Of course. All this should be a part of any OW course. It's not hard, but it's certainly hard to dive intelligently without knowing about it.Can I quote you on a FB note, with a link to your comment? This is useful stuff.
I do weighting a little differently, but wanted to share this nonetheless.Of course. All this should be a part of any OW course. It's not hard, but it's certainly hard to dive intelligently without knowing about it.
This is a great demonstration on why to use the least amount of weight possible. The less air you have in your BC to maintain neutral buoyancy, the less there is to compress as you dive deeper. I rarely use any exposure protection and I rarely have any air in my BC. Ergo, my depth rarely impacts my buoyancy. I can descend to 130fsw and back up to the surface using only my breathing.
Whatever works, works. BTW, I noticed a huge typo in one post. Male average vital capacity is 4,600ml, not 2,600ml. It's still 10 pounds of buoyancy, I just copied the raw data wrong.I do weighting a little differently, but wanted to share this nonetheless.

And we completely disagree.
Most of the cool stuff is close to the bottom, and often under outcroppings right at the bottom. You can't see it unless you're really flat. As for looking ahead, tilt your head 30 degrees to the right or left before you try to look straight ahead.
Rototillers was the name given by our dear old @Uncle Pug for those who were determined to dive with their feet down. Why? When they got close to the bottom, the thrust from their fins stirred the bottom and utterly destroyed the visibility behind them. Oh, they had great vis, but not anyone who was behind them. More often than not, they had no clue of the devastation in their wake. There is a discussion way back in time, where a guy claimed that he just doesn't silt others out when diving with his head up, legs dangling and then his buddy chimed in. It was truly a candid discussion. Denial: not just another river in Egypt.
So, some get the important relationship between trim and buoyancy and others just don't. Master trim and buoyancy and watch your control, comfort and fun increase significantly. That, or let the vagaries of Boyels law and vector forces master you.
I beg to differ on this, but that position is pretty standard the world over. It shouldn't be, but it is.
If you ever need any tips on vertical trim let me know. You seem to have some misconceptions.Caveat: I do go vertical on every dive, once I'm on my deco stop, whether it's mandatory or precautionary. I rotate and look for approaching boats as I ascend from that stop.
