Delta IV / FDX-10 Noise

[shorns76]

Hi guys,

Hoping someone from Oceanic can give me an idea of what's going on. I just purchased a new delta IV / FDX-10 with DVT. Every time i've dived on it i get this rattling sound from the 1st stage (some people have described it as a honking or telephone ring type noise). It only occurs when inspiring a little deeper than usual and seems to occur at higher tank pressures (around 160-230bar). Despite this the reg breathes great and i've noticed no problems at all.

I have read reports that this is the DVT mechanism causing the noise however i have the red bullet, not the white and i've read that the red ones should not exhibit this problem.

Unfortunately i bought the unit from divers-supply in the US and live in Australia so can't just walk back into my LDS with it so would like some advice what to do.

Thanks!
Sean

It might be a harmonics issue in the first stage,,,fairly common issue in certain regs.. I would think any Oceanic Dealer even in Australia would honor the manfc. warranty.
