Temperature differential

[pkaquatics]

I have two VT3's and the temperature readings are 6 degrees off from each other. Alos when comparing them to 2 digital stats the closest one is only within 3 degrees. i.e. Digital 68, one computer is 71 and the other is 77. Any suggestions or can this be normal?

I am experiencing this problem also. I have a VT3 which has displayed the correct, or at least close to it, temperature for about 60 dives. In April on a trip to Turks and Caicos, it displayed a temperature about 6 degrees colder than my buddy's Atom 2. I thought maybe I hit a cold patch, but it occured on multiple dives and different sites.
