Hey everyone,

I switched to a tub setup and I have a digital thermometer with the probe on the UTH and it is reading 84..2. I have my accurite probe inside under the paper towels laying against the tub ( inside of the hide ) and it is reading 101.3

I have the UTH plugged into a Rheostat and it is turned all the way down. I have about 1" clearance under the tub, so heat doesn't build up.

Why are my readings so far off and which one should I trust. Thanks for any help you guys can offer.
