VR3 - 11 hour Deco

[Sludge]

The reason I noticed it was because the "Too Fast" alarm was sounding. Every second it read a different depth - 62...48...93...112...38...55...

Going from 112' to 38' in one second is DEFINITELY too fast an ascent!

Ha, very true. The programmer should have written some code which would detect this error and display "I'M BENT" on the display.

My DR Duo and my buddy's DR Trio were both freaking out on us during deco after a recent dive at JB. Both are back-up computers, so no great cause for concern, but it was annoying to hear the "Too Fast" alarm ringing throughout deco. It was strange to sit perfectly still and watch the depth change radically at impossible rates.

On later dives both computers worked fine. I will have to try letting my Duo sip some ear beer next time I dive.

My VR3 locked up a couple of weeks ago at the end of a longer dive, around two hours bottom time at 80 to 100 ft average depth. I tried to change gasses, it would not respond, that was my first indication of a problem. I decoed out on my bottom timer using the modified exponential hungarian method, then went to dinner. While at dinner the topic of my dive came up, I went out to the car and got the computer, it still said I was at 83 ft for 112 minutes - two hours after I had exited the water (45 min of deco BTW). Pushed the buttons a few times, it unlocked. Strange thing was, it had the correct profile and time for the completed dive in the log. I don't trust it anymore, replacing it with a Shearwater. The VR3 was getting hard to read anyway - eyes are aging.

What's this? Do deco until you get hungry?

That's part of it - the method was developed by the training agency that I founded - AFU divers. If you dive AFU, decompression is really more of a state of mind than a physical transient - if you think that you can surface, and you're hungry, "go for it"!!
