And with a heavy steel cylinder.
So I came out of the sea after 40 minutes with numb hands and a numb face, and couldn't even stand (wave/weight combination) and couldn't get my gear off to get out of the waves (numb hands/wave combination) and eventually, having being dragged out of the surf by my buddy, I didn't even have the energy to remove my gloves. Talk about exhausting,
Note to self:
Dry suit leaks. Needs attention.
BCD doesn't inflate. Needs attention.
Too much weight. Needs attention.
Too many under-layer? Needs attention.
Anyway, I didn't die. So, that's good.
