Aqualung Legend supreme

[Dave Kay]

I just bought my new Aqualung Legend Supreme regulator and tried it out in the pool before a dive trip coming up. I noticed that when the regulator is out of the water it makes and odd sound when I breath. Ill call it the goose honk. I did the position where one would lay back on the surface after a dive waiting for the boat. If the water is choppy I often keep the reg in my mouth and I always climb back into the boat with a reg in my mouth. It keeps making the same sound. My 12 year old reg never did this. Mares Micron.

I went to the dealer and they took it apart and showed me the diaphragm in side and said that its very thin compared to old regs and this increases ease of breathing, but the trade off is that the diaphragm flutters when not wet, like in situations above. It's hard for me to believe that aqualung would allow this kind of engineering to be allowable. I don't like the sound, it makes me think the reg is either malfunctioning or junk, so I'm very skeptical. Can someone comment on this please.

Its like the dealer said. Many regs do that not just the AQ Legend.

honking when exhaling? that's relatively normal at the surface. Aqualung is not the only one that does it, plenty of other reg manufacturers diaphragms do the same thing. Not a whole lot you can do to fix it, and there really aren't many regulators out there that are guaranteed to not have the goose honk.
A lot of times if you fill the housing with water and purge it again it will stop, at least temporarily.

I know at least the aq legend/titan/core (also other brands) also does this on the inhale, if dry.

Agreed, that vibration is not uncommon. But one more thought: are you using the original mouthpiece or did you swap it out? I have sometimes found that noise will vary with the type of mouthpiece attached.

Almost every reg, regardless of brand or model, I have ever owned has "honked" to varying degrees on land. As others have said, it's normal and nothing to worry about.

I know that goose honk sound. I also have an AL Legend. It is annoying but I’ve had it on many rental regs as well. I will inhale and exhale out the side of my mouth where I leave a crack between my lip and my mouthpiece when at the surface to avoid the goose honk. When water comes my way or if I need to duck down, etc., I can still seal my lip around quickly and breathe off the reg. Very normal.

Original mouth piece. it's odd for me though. I been diving since I was a boy, 50 yrs and never heard such noise as this. I called Aqualung and confirmed that they say the noise is normal. I used to have a mares mikron for 12 yrs before this. I've also never heard this from others on the trips I've been on. So it bothers me but guess I'll have to live with it. Thanks.
