So I'm looking into these thermostats and thermometers and I just had a question about the set up that pretends2bnormal posted. Do I need to get a probed thermometer as well? That may seem like a silly question but I've been using one of those laser thermometers to measure the temps of the tank in general.

The thermostat is just for the heat pad, right? Sorry if that's silly, I just want to make sure.
