Quiet here ...........

I owned a Poseidon in the seventies, using it for winter cold water diving. It has an inlet and exhaust on the chest. The worst thing you can do in a drysuit is work up a sweat. We used to ventilate heavily to keep from getting sweaty underwater. At times, we would blow up intentionally under a boat to wedge ourselves between the bottom of the boat and the shaft or cutlass bearing, or just to stick to the bottom of the boat. But once done with a dive, it was very relaxing to get clear of everything, and blow up while laying horizontal on the surface of the water to get the suit off your underwear, and just shake everything out. But you couldn't blow up too much, as you still had a harness on. The tender reeled you in like a bloated whale, and you'd exhaust and deflate right before climbing the ladder.

Nope. The SCUBA instructor has offered free lessons many times, but I already have enough going on in my life without adding that.

Ernie, I would try it once. Even if in a pool or shallow protected waters. It's other worldly. I had two dreams when I was a kid. One, I could fly, and the other, I could breathe underwater. I got to live both of those. The flying experience came after about ten skydives. The underwater one was with the first breath of air with my head under water. Have you ever been down in a helmet on a dive? Very different, but somewhat similar. Just take it slow and easy as you would anything else that can kill you. ;-)
