Why do apnea dive watches not vibrate?

[Gab]

Hi all,

I just took my brand new Aeris F10v2 out for a spin in the Mediterranean last week. I had my 5mm with a hood on and I did not hear the alarms nor did I see the red led light up. I started to think it was faulty but after several tests I realized my hood completely blocked the alarm's sound (and the light is just not bright enough). This made me wonder why they don't vibrate, wouldn't that be better? I would feel it even through my wetsuit, I would not miss important events and not have to look at the watch all the time.

Any ideas why nobody does this? It would be more safe.

Thanks,
Gabriel

Battery life, likely. Vibrate kills batteries.

With my 5mm, I often don't hear my f.10.

For competitions, ppl put the watch in their hood or around their neckweight to be able to hear it better.

Hmmm, ok, fair enough, although with smartwatches out and not being much bigger than an f10 I wonder how valid it is today for them not to integrate a rechargable battery, a monochrome screen and the not powerful CPU the dive watches have requires less energy than what the smartwatches have...

That's a good point. I've given up setting depth alarms as I just can't hear them. There could be an option to turn vibrate on/off which would improve battery life. Perhaps there's a space issue within the watch also?

i think it could be to do with air space. to vibrate there would need to be space for a mechanism to move and then the air in that space would then be compressed at depth making a vacuum and break the watch.

Hmm, interesting point, I wonder if that could be it...a phone's vibration unit is a small flat cylinder that has a part that spins inside (at least that was how it was 10 years ago).

Because you will buy the amazing innovative new version which will include the amazing innovative vibration function
