Kraken video by Alec Peirce

[tbone1004]

Video on a bunch of the old issues with traditional double hoses. @Sam Miller III can hopefully give us some more info that Alec called out as him forgetting
and what @Luis H @herman and @OWIC647 went about trying to fix with the Phoenix/HPR upgrades. Kraken video coming soon I hear

[Bryan@Vintage Double Hose]

The Phoenix first stage was and is a real boost for double hose divers. There are over 500 of them out there around the globe! The biggest performance improvement was the HPR 2nd stage and new diaphragm. It is miles above the original horseshoe design. When we first sent them out we were afraid the regulators they went in would breathe too easy and the divers would object to the venturi improvement so we put spacer washers on either side of the 2nd stage spring to throttle it back a little.
.5 is easily achievable and you can go lower but they tend to freeflow too easy. With the above setup all that remains is Position, Position, Position of the regulator on the divers back and you will have one smooooooth breathing regulator. Even Luis has not found a way to defeat physics but I'm sure he's trying
