aeris dive computer removing dives?

[aamax]

I have an aeris elite and was trying to retrieve my dives yesterday. all the dives from 2005 an prior are gone... is there some kind of limit to how far back the dives can be saved? There aer less than 40 dives on the computer... very disappointed to have to enter them in by hand...

thanks

The number of dives saved is affected by a few things

The number of dives
The sampling rate used
The amount of memory in the dive computer

The older dives are overwritten to make room for the new dives when the memory is filled.

I have the sampling rate on my Aeris ATMOS AI set to 15 seconds. I would love to set the sampling rate to 2 seconds but do not do so because I would risk overwriting dives done earlier with the vacation if I did enough dives during a two-week vacation.

You wold think that with the price of flash memory dive compute manufacturers could afford to add more memory to the higher-end dive computer like the ones you and I own.

They added more memory to the Aeris Elite T3 and the Oceanic VT3 but my guess is that was to allow for storage data associated with the monitoring of three different air sources.




That is why they provide the capability to download the dives to your PC.

I think you made your own point here. For the most part these little underwater electronic hockey pucks are just a little electronic device. The cost of adding memory is slight. Since they are designed and built by a few companies for the brands in what is really a niche market the designs do not get changed quarterly like some mass market items.

Even more note worthy are soft features like multiple gasses etc. It costs no more to load one program over another and the hardware changes are slight but the price difference can be significant. In the end features are simply held back or disabled to differentiate between models.

To the OP poster....
The long term solution is downloading to your home computer to archive as you wish. On board storage can be manipulated as mentioned with the sampling rate but that is of limited value.

there aren't that many dives on the computer... and it just seems strange that the cut off is the 05 year... everything after that is still present.. you could be right but my old UWATEC (very old) stored more dives... but then again, not all of them had the dive profile info saved so that could be it...
thanks for the reply

I believe that the limit is 24 dives.

[DiveMaven]

My Aeris AI only holds 24

[garyfotodiver]

My Atmos 2 has six dives on it. It retained the first three dives, but the others have not been retained. The manual states it holds 24.

I think I'l post this in the Aeris forum.

Keep in mind that 24 is the maximum number of dives
that are tracked. There is also a limit to the amount
of profile data that can be stored. When the profile data overflows
or wraps, profile data from previous dives will be tossed
as needed and those previous dives while still there, will
no longer have any profile data.
ACI used to download all the dives and it was possible that
some of them might not have profile data since the profile
data might have overflowed. It apears that the latest versions
of ACI no longer download dives that don't have profile data.
So if your profile data overflowed and caused the loss of profile
data on dives, you can no longer download the dives that lost
their profile data, they won't show up in the download list.

I believe that the memory on the ATMOS 2 is the same as the AI.
This means that you can get about 16 hours of samples at a 15 second sample period. Using 2 seconds you end up with a bit over 2 hours.
