1994 Mares computer bought on EBay........

[SADS 669]

I got a great deal on a pressure gauge and hose on eBay for 12 bucks, it came with a 1994 vintage Mares dive computer no battery life left

any idea how to change the battery, it looks like a sealed unit with no visible screws and before I Shrek it in the vise I thought a question posed would be smart

any help would be appreciated

How's that?

I think that is an old uwatec bottom timer (not dive omputer, it did not run any nitrogen loading algorithms). Mares and others? Resold it. The original models were sealed and batteries are not replaceable once the unit has gone dead as the sensor calibration was stored in memory.
but I could be wrong...

If you google a bit you should find more detailed information.
