Infrared Thermometers

[ScottsTot]

Has anyone used infrared thermometers for their tanks? https://www.amazon.com/Etekcity-Las...8-1-spons&keywords=infrared+thermometer&psc=1

I tried out a few thermometers made for aquariums in the past and they all suck.

I’ve used IR and they work pretty well as long as the laser is pointed down from the top to the sand or rock. Hit glass and it’ll bounce around and give a less accurate reading. However once I got a controller, I only go by my temp probe.
