Oceanic DataMax

[Dewit2it]

Any service shops in the north east WI area, that can check/calibrate the analog gauge part of it?  Oceanic will no longer rebattery/calibrate it. 

I popped it open and replaced the batteries and cleaned the surface rust off the metal diaphram from some moisture that did make it inside.  I removed the silica gel packet as it was orange from the moisture, so it needs a new one.  I cleaned and lubed the rubber diaphram and put it back together minus the packet.  All it needs now is to be checked for accuracy in a pressure chamber.

I mounted it in a wrist mount and freedove it on two of the markers on the RG compass course.  Where my ProPlus2 computer read 14', the Datamax read ~15'.  At 19' it would read upwards of 25'.  So it appears that the gauge "lies" on the deep side, which is much better than the shallow side.  It was cool to get a cumulative bottom time of 25 min (below 7') from all the pop can and other dives I made. (just keep all dives within 10 min of each other)
