Oceanic VT3/Oceanlog Question

[Sub-Mariner]

I recently went on a series of dives over the course of 4 days and my VT3 worked flawlessly without incident. At the end of the trip I downloaded my dives to my computer a process I have done often. I noticed that the 1st dive of the series would not download. I checked the internal VT3 logbook and the dive appears in it but there is no tank data. During the dive tank data was displayed normally. This is the 1st time I've experienced this. Has anyone experienced this or have a clue as to what happened?
Thanks

The VT3 (like most other Oceanic computers) has a very limited memory. I guess your sampling rate was set to 2 sec. When the memory is full the computer starts to overwrite the first dive again.

See sampling rate vs memory here: http://www.oceanicworldwide.com/pdf/compare_computers.pdf

Simply switch to 15 sec next time, that's sufficient anyway.
