Right, I was diving on Sunday at Capernwray, mostly teaching Sports Diver lessons.

Anyway, one of my students lost a fin on juming in and I did a hasty recovery, dipping down to 6m to grab the thing and returning slowly to the surface.

When I downloaded my dives in the evening, my profile showed no record of it, either as a separate dive or as part of the dive immediately following.

Now it is a while since I read the manual, but I thought the Aladin logged every 20seconds, so a 90second (ish) dive + a minute or so on the surface putting the fin back on should show up on the profile?

I'm wondering what went on in its little electronic brain.
Anyone else seen something like this?

I have had occasional teaching dives before where I could have sworn I did one more CBL or AAS than the profile showed, but put it down to bad memory on my part.

If you had just surfaced and immediately went back down, the chances are that it continued with the dive you had just surfaced from. I can't remember how many minutes has to pass before it knows you are on another dive.

Ah, but it didn't.

I know that if a surface interval on the aladin is less than a couple of minutes it counts as one dive, that isn't the problem. The problem is that I don't see the ascent and surface time AT ALL on the profile graph of the dive, it begins with the 2nd descent, direct to the helicopter at 17m, nor is my little 6m dip a separate dive, it just ain't there.

Now it may be that in deco terms the computer doesn't think it is worth anything, so it just dropped it as irrelevant, but I'd like to know why.

Sorry Ian I read your first post incorrectly, I thought it was the second decent / ascent which was missing.

I have no idea why the first one is missing, I haven't come across this before.

I'll check my manual and see how long the dive has to be for it to be recognised.

Iain,

I tried my Gekko out in Capenwray in about July and found that it wouldnt always recognise that I was underwater until about 3m.
I didnt fancy doing many dives with it like this so I sent it back and Suunto acknowledged that something was wrong with it so sent me a new one :)
That might explain it.

It definitely was on & knew I was underwater, no problem there, just
seemed to forget afterward, so I wondered if any Aladin owners
had seen this.

Iain I have just checked my old Pro Nitrox manual and it says the dive has to be at least 2 mins for it to register as a dive.

That'll be it then, thankyou.

Also just found the manual is online at:

Probably time for a new computer soon.

Iain (different spelling, but you solved my problem so I won't hold it against you).
