We scheduled two dives on Jan. 28, and I wore the Mares Puck looking forward to accurately logging my dives with the benefit of me being able to read the dial with the large LCD letters compared to my old dive computer. During the descent to about 60 feet for my first dive, everything was working well, then later in the dive, I looked at the screen and every LCD value that it could possibly display was being shown and it was non-responsive to any button presses. My wife's Aeris XR1 computer worked flawlessly for both our scheduled dives with a more difficult battery replacement procedure than the Mares Puck computer. Upon getting back to our condo from the dive, I carefully removed the back to inspect the rubber gasket and battery and everything looked fine. I did not note any visible water or moisture inside the unit as well. After removing and reinserting the battery, the computer "rebooted" and it looks like it functions again, but needless to say, I cannot trust it and I am extremely disappointed.
We got home to Colorado from Hawaii on Jan. 31, and today, Feb 1, I unpacked our dive bags and logged on to Amazon to start the return process and was distressed to find that the return policy expired Jan. 31, so it appears I'm stuck with a lemon dive computer. I did not rate this one star as the description for that is, "I hate it", so I rated it two stars because I actually like the computer but extremely disappointed that it failed on first use. I really hope that the seller or manufacturer reads this review and contacts me for a replacement as it really is a shame that my purchase and first use did not allow enough time to return it in the event there was a problem. If not, my advice to others is to beware this particular model and only purchase it if you can dive with it within the 30 day Amazon replacement policy.
After not using it for six months, I went diving again and it seemed to be working fine. Then after the dive, I went to the logbook function to pull out my info and it wasn't working anymore. It showed me the summary screen, showing 49 total dives, but then would not pull up the individual dive info screens and just went directly to ESC screen.
Emailed Mares support to see if I can try anything to fix this while I'm in the middle of the pacific and have a dozen dives planned. Their response was just to contact the dealer... Not even a suggestion/procedure to restart it. So now I'm stuck paying for a rental diving computer, probably spending more money on the rentals than I originally spent on this piece of junk.
For the next dive, I got a rental Pro puck and this guy. Seemed to be working fine on the surface but once I went under, the Puck went berserk - shutting down and then randomly restarting once in a while throughout the dive. Luckily I had the rental with me and was able to continue.
Fortunately you can get replacement parts for the battery door.
Earlier today I went on Youtube to see if anybody had posted a video for properly replacing the battery on this model, and there is a single video showing this, and as soon as he unlocks the door, it pops out with no other manipulation. I was floored. I wish my model operated like that. I've replaced the battery in two of these, and neither opened like that. Both are epic struggles to get that door off.
When I get the replacement door, I'm going to lube that o-ring and door up with so much silicone grease so it is more functional to get the door off next time I go to replace the battery.
My only other complaint about this DC is that the transfer cable is prohibitively expensive. I'm happy to have a DC with bare minimum features for recreational diving at a good price, but they do make up for that price with a super expensive cable - and transferring dives is pretty hard on the battery, as fast as it is.
