I really have heard no beeps underwater, but maybe I haven't ascended too fast yet.


Download the dives to your computer and you will see if alarms have gone off. If you have heard no beeps then I am confused as to this thread. How can you "barely hear" what you have never heard?

I meant with respect to the ascent alarm. I only heard (barely) the beep underwater when I forced it to beep by going in and out of dive mode.
 
Guys! I am just trying to see if my Cobra 3 is defective or not. I just need to know how common it is to NOT hear these things underwater. My beep makes the beep - but it is just very quiet underwater.

ScubaSteve apparently has the same problem. Who else has the same issue, so that I know that this is just how they are, and I do not need to take my Cobra 3 back!
if you want to be sure to hear a Suunto alarm, you have to put the computer under your hood.
every Suunto owner will agree.

As a Suunto fan, I half suspect Suunto believes that their relatively quiet beep is an advantageous feature, not a disadvantage, just as Suunto apparently believes that the relatively conservative RGBM algorithm is an advantageous feature. Suunto does seem to have certain design biases that not everyone shares. I turn all audible alarms off anyway, since I find loud beeping obnoxious. And as I've said in other threads, the conservative algorithm appeals to me.
 
Diving in Canada, I always use a 7mm hood. No way can I hear my cobra 3 beep. Maybe on a warm water dive trip?

It is an extension of that annoying extra layer of thermal protection that us "non-warm water snobs" have to wear :D.......many of us while diving in a saline deprived solution.
 
I agree, 'no news (beeping) is good news' from a dive computer. However, if a person does do something wrong (none of us are perfect), a beep to let us know certainly does not hurt. In fact, it HELPS..... and for some divers, may be just what is needed to wake them up and make them pay attention. The alarms and beeps are there for a reason (as a reminder). If they are so faint that they can't be heard, then it defeats the purpose of having the alarms there at all.

We also should not speed in our cars. But, according to Dr.Mike's theory we don't need police to slow us down when we are 'in violation'.
If a fellow diver isn't paying attention, I'd rather that their computer beep at them, rather than having that person get DCS and ruin a dive trip for everyone on a liveaboard.
