Apeks XTX 50 honking

[ScubaERDoc]

Just dove with my brand new Apeks XTX50 DST. Breaths very well at depths but at surface honks loudly. Any thoughts what's wrong? Should I be worried? I have another week of diving in Curaçao and obviously can't get to me LDS

Honks both inhale and exhale. Feels more resistance above water than below. Played with flow valves already

My XTX 50's are brand new, just set up by a tech dive shop and they do this on the surface. First time I breathed them in air I was shocked. After first service and setup they are the same. As far as I know this is how they are. Other comments on this?

Dry diaphragm vibrating. Common and nothing to worry about.

Try a quick vacuum test. Try to breathe in from the reg without it being attached to an air source. If you can breathe in, the diaphragm is probably not sealing properly. If it locks up, then it's doing fine.

Forget about it, in some circumstances it happens on the surface. I a have at least 4 seconds stages resonating on the surface 1 scubapro 2 zeagles and 1 apeks. nothing to worry about.

As others have said its not uncommon, as long as it's holding vacuum I wouldn't worry. I own XTX50s and mine will "honk" out of water but once under no problem.

Thanks all! My xtx50 has been working well otherwise and am reassured that the honking is normal. Curaçao rocks by the way. Superior Producer dive tomorrow

Have some one who 'knows' take off the front cover and there is a plastic retaining ring that holds the diaphragm in place....Make sure the diaphragm isn't 'wrinkled' slightly and properly seated in the housing...Put the ring back on and carefully screw the cover back on....Simple fix that should stop the 'honking'......FYI, if they are still using the chrome plated retaining rings [chrome has no real practical function, you can see it thru the cover], get rid of it at some point and get a non-plated one....Salt water corrodes the chrome plating over time and flakes off inside the housing....
