First time

[Creed]

Well, tonight I jumped in the pool with the DA. First time for a dive with a double hose. The biggest difference for me wasn't the work to breathe, but rather the way it varied depending on your position in the water.

I did a lot of hose clearing drills, mostly because I didn't order a duckbill yet, and was too eager to wait for one I quickly learned to roll, although I am not sure I am doing it right. Starting from a face down position, which shoulder should point down first? When I get on my back during the roll, it literally blows air and water into my mouth. Is this just something to get used to? However I did it, it worked like a charm, and cleared the hoses without issue.
I also decided to start practising with my Turbo Fins instead of my Force Fins.

Roll left shoulder down exhaling during the roll. Yes, it will freeflow when you are on your back. No way to prevent it.

These pages from New Science of Skin and Scuba Diving have been shown elsewhere, however they may be appropriate again:

You will find you don't necessarily have to do a full 360 degree roll. Getting the back of your left shoulder down and blowing the water out is really all that is needed most of the time. Just let your shoulder stay down a moment or two first to allow the water to make it's way past all the corrugations in the hose. No aquabatics necessary.

Or just hold it over your head.

You might oughta get that duckbill in there before you use it for real, it kinda needs to be there.

This will purge the intake hose and mouthpiece, but will not purge or drain the exhaust hose.

I know. I'll order one shortly. Like I said, I couldn't hold off any longer

Why didn't you just say something when I rebuilt your regulator? I didn't send one cause I figured you had one or two.

True, but if a duckbill and cage valve were installed and the intake hose was cleared by holding over his head to get flow then purging the exhaust hose is a piece of cake at that point.

The methods described by the picture in this thread I find useful.
