Hi,
Was at a 20m deep quarry last weekend and because the water was 4^C I saw 2 x freeflows in the 2 days I was there. Its not a suprise to me knowing that cold water lends itself to regs freezing up.
But on the 2nd freeflow at 16m the diver went to airshare with a buddy to the surface. And it occured to me that the extra demand of 2 x divers on the same 1st stage could potentially have resulted in the 2nd set of regs to freeze and freeflow too.
I know there were other potential options in the above freeflow situation at 16m (sipping air & CESA from 9m if necessary, cracking the cylinder valve on and off as needed, etc).
But my question is: during a situation where one person is out of air completely and has to share air with a buddy in cold water, is there a way to minimise the chances of the air-shared set of regs from freezing on ascent?
