New twin Geo's read different temperatures

[Mike]

I just bought 2 identical Oceanic Geos, they consitantly read about a 3 degree temperature difference. I've tested them in air and water. I've done a controlled test, filling a bucket with water and putting them both in it side by side and leaving them alone for an hour and they read different temperatures.

Is there a temperature adjustment feature to these dive computers?

From experience I can tell you that +/- 3 degrees is within spec for these computers. You can send them back to oceanic to be calibrated or replaced if they are way off, but if they are within 3-4 degrees of the correct temperature, and within 3 degrees of each other, you are doing well and I wouldn't mess with it.

My family uses several oceanic/Aeris computers and from lowest to highest we have about 5-6 degrees of difference on any given dive, with the correct temperature being somewhere in the middle.

I heard at one point Oceanic was having some sort of problem with their temperature sensors (or whatever they are called) but that was awhile ago. I had one computer that was consistently 6-7 degrees off and sent it back for adjustment.
