Display turns off whilst underwater diving

So I recently upgraded my Garmin Descent mk2 to the Garmin Descent mk3. I love all the extra features of the mk3 and its better battery life, but then I took it diving....

I've taken it on 5 dives now, and no matter how many times I have checked to make sure the setting is 'DISPLAY IS ON', it always reverts back to timing out and going black at 15 seconds.

Having the screen go black underwater every 15 seconds ona  dive computer is not only dumb, it is unsafe. As someone who is carrying a large camera system in one hand, or tools for working, having to try to contort your arms together to press a watch button to bring the screen back on to check your depth, ascent rate, deco time etc is really annoying, and completely impractical.  I don't want to have to press the watch button every 15 seconds to see how much longer on a safety stop, or more importantly, when checking my ascent rate from depth. I also have found that neither the wrist movement or touchscreen will activate the display underwater.

The Garmin mk2 always had the screen on during diving, and it worked perfectly. Now that I have discovered the mk3 screen won’t stay on whilst diving, I’m regretting this upgrade (downgrade…).

If someone has a fix for this, please share. Or if Garmin read this, please change the diving display setting so that the Garmin Mk3 can actually function as a safe diving computer.

  • I went for a dive today, the screen kept going black throughout the dive after 30 secs. So at the end of the dive I filmed it with the GoPro.

    This is what is happening when diving with the Mk3i. As you can see, it goes black after 30 secs and neither the touch screen or hand gesture turn it back on. You actually have to press a button, this is not a good feature for a dive computer. It's dangerous.

  • Definitely strange, I’ll check it out tomorrow, but I’m pretty sure mine responds on tap on screen and never goes black. 

  • Curious, can you share your display settings for diving? This is a pretty serious issue and I'm trying to replicate but I can't. Are you on 16.25?

  • Software is up to date with 16.25.

    For diving settings, I have Display is always on,  double tap to scroll is on, and timeout is 15 seconds.

    One thing I've noticed, in the advanced dive setting, it has Touch as disabled and it's greyed out. I can't change it.

    Regardless of settings, as a dive computer it should override everything and the display always needs to be ON. Having a dive computer that goes black underwater is incredibly stupid and dangerous. If this can't be resolved I'm going to return it. Which is a shame because on land I really like it.

  • Touch screen is disabled by default since it doesn't really work underwater.

    You are correct that as a dive computer it should keep the display on at all times and not even allow you to change that. The reason I asked for your setting is to see whether there is a bug in a specific setting combination that causes it.

    If it isn't software related, then I guess you're better off returning it.

  • I originally assumed it was a bug with my watch. But after reading this forum it sounds like several other users are having the same problem. Which means there must be one setting that needs to be changed, but we don't know what that setting is....

    Regardless, Garmin need to fix it. I used the MK2 regularly and it was fantastic, never did something unsafe like what's happening with this Mk3i.

  • Yes either it's a specific combination or somehow you have a faulty device. 

    Can you try these specific settings bellow and check to see whether anything changes?

    Settings->System->Display->In-Dive

    Brightness: High

    Timeout: 4 seconds

  • Yep, can do,. I've got a couple of days off from diving, not back in water until next week.

    I'm wondering if anyone from Garmin is reading this and realises that they have a fault with their dive computer?

  • It sucks that's it's tricky to test without actually going for a dive or somehow getting it under pressure Disappointed

    Usually when staff reads they comment. We should report the bug but at least we can try to troubleshoot a bit first.

  • Yep, the only way we can try to resolve this is by changing settings, dive, change settings, dive, change settings, dive etc until it actually works. Rofl

    Hopefully that video is of use to Garmin, shows pretty clearly what the issue is.
