We have had our 1 year old beardie for a couple weeks now. We have a dial thermometer - and I know they are inaccurate now. We have a digital one on the cool side of the tank which tends to show temps in the low 80s. The dial one only shows maybe 90. It has to be warmer than that in there. But I can't know and am hoping you all might be able to recommend a reasonably priced alternative. Thank you!
