Temp guns are awesome for quick scanning around and looking for hot or cold spots, but not very accurate so don't take them as being dead on. It's not something that you're going to really get much of a better one usually by just spending a few more dollars on. Most any of them from pro exotics, reptile basics or off the shelf at home depot will do you just fine. They pretty much all have an accuracy rating of +/-2% or 2 degrees F whichever is greater. A few may be slightly better shaving off up to another .5 off of those numbers, but you're probably not going to find anything significantly better without jumping up into the 600-700$ range or more for one.


fyi, Hospital grade temp guns are more accurate only when used on people, if they're being used on anything else they have a different accuracy rating and many have a switch on them to change it from people to other surfaces. Many of these are also only point and shoot, calculating a reading at a certain spot as opposed to being able to hold the trigger and being able to scan across a surface.
