Suunto Gekko reverted to Air and nearly ruined my day

[reefduffer]

As you describe, I entered the set %-screen, pushed the number up and down once or twice and settled back on 30% and hit ok. Not sure what else I could have done to avoid it.
Henrik

The workaround I was thinking of was to [for example, if the target is 30% as you say] set it to 32%, accept that, quit, quit, quit etc., so the FO2 is actually set at 32, ready to dive.

Then immediately repeat, setting it back to 30. If that doesn't reset the timer, I'd be more surprised than the behavior you previously described where going through the set screen but not storing a change doesn't reset it.

handben look at page 28 and 16 of your manual, base on your description and how you disregard warning of you computer I think you will find your answer. All dive computer manufactures and openwater book say the same thing don't share your dive computer on the dive. You should have aborted the dive.

Just a quick question, folks. Anyone around here ever do tables, SPG and a dive watch?

NCadiver, thanks for pointing me to the page in the manual describing the 2 hour limit to reverting back to 21% O2. I'm not sure I follow your logic about aborting the dive though. Having the computer operate on Fi O2 of 21% rather than 30% renders a more conservative profile. Be that as it may, I still don't understand aborting a dive with perfect dive conditions and plenty of gas as well as a properly functioning regulator. I dove without a computer for some 24 years and did quite a few dives just fine without one. Now I don't know about you, but I'm just not out 20 miles at sea 120 feet down with a couple of good buddies all that often. I'd much prefer to dive (conservatively) than abort a dive due to a computer glitch. But maybe that's just me.

Good point. Thanks, I'll try that next time.

All the time for technical diving

Tell me more about the tables you use. I see you are a TDI and GUE diver. Which tables do you find best for you and why? Have you ever had an SPG implode due to depth pressure?

 

[drbill]

I had a dive computer (brand unnamed) which switched from air to 50% nitrox and told me I was dead on a dive. It did this several times although to varying mixes. It now rests in a garbage dump somewhere near the manufacturer's head office!

Another one loved to tell me I was ascending too fast when I was stationary at depth filming.

The second turned out to be a dying battery. The first may have been the same, but the battery required factory servicing.

But the whole incident played heavy on my mind and made the first dive much less fun, as I was having to concentrate more on equipment issues than the dive itself.

The leason I learned is to be darn sure to set your computer correctly Before the dive. I hope this helps others who are planning similar dives. Ben in Baltimore

That why I said you should have aborted the dive we your computer hit deco.
