Goodmorning, I went out yesterday before cleaning my frog enclosure and bought the zoomed digital thermometer that you put the little probe inside the tank and the yellow part were your reading is sits outside. The problem im having is before this I used the all living things digital thermometers, they are little black circles that you can stick on the wall. Now that I have changed to the zoo med one I cant hit my temps. The all living things thermometers are always 2 to 3 degrees higher. And I have 3 of them and any were I put them in the house they will all read the exact same temps. I put one in the enclosure today beside this probe and it was 3 degrees higher. My question is now that I have discovered my temps are off and its driving me nutz would you go with the zoomed one or just stick with what I was using. I figured I go for the name brand that's why I decided to change. Any advice would be great. Oh and yesterday before I put the zoomed one in it 73f which was exactly what my thermostat read for the room temp, this is why im stumped.
