I was browesing Yahoo answers the other day and came a cross this thouth it was very interesting and some I should share with you.

What might cause my scuba regulator to wheeze when getting low on air?


I have a brand new first and second stage from oceanic. I've taken the equipment on two dives so far and both times towards the end of the dive I would hear an occasional wheezing noise as I inhaled. Couldn't tell whether it was first or second stage reg, or the hose itself. Anyone have this issue before or know what it means? Thanks for any help. I'm with DMG - if you haven't had your reg in to be serviced, take it in. Your primary regulator should never 'wheeze' or 'honk'. It's almost certainly the second stage.

I learned recently that it's not unusual for regulators to ship from the factory *not* correctly set to factory specs. I've got an AquaLung (the one actually built by APEKS) and when it came back from its first annual service I had to learn how to handle it all over again because it seemed like it wanted to free-flow. Turns out, my reg was not set right to start with (not bad out of spec, but the difference was noticeable).

i would take it back to were you got if from that doesn't sound normal. i have never had that issue before but i don't have a oceanic.

Your regs need to go back to the shop to be serviced. And you should never go below 50 bar. People who do, need their head examined.It's just too dangerous.
