UTH not hot enough on inside of tub?

[PokeyTheNinja]

Yes, it is pretty high which is why wish the heat would translate to the bottom of the tub so I didn't have to turn it up so much! There is two probes, one from the thermostat taped to the bottom of the uth to regulate it's temp. The other one is a thermometer probe measuring the temp of the bottom of the tub on the inside, the basking spot. So you're saying this one may pick up the ambient temperature more than give an accurate reading of the actual basking temp, which is why it seems cold on the inside?

It could be. A thermometer gun is more accurate for direct spots and they aren't too costly. Most have them on hand just to get a better read or that's what they use instead of a thermometer with a probe. Not saying you should drop your money or that it's the cause but thermometer guns are quite nifty.
