NOTE: The red laser that is available on some temp guns DOES NOT measure temperature! It is a separate beam that simply serves as a pointing device. The surface temperatures are measured using an invisible infrared beam. The red laser can shoot a very long distance, across the hall, across the building, across the street. The INFRARED beam only shoots (effectively) a short distance, typically a few feet. So while you can use a “laser gun” and see a red dot on the wall 50 feet away, you ARE NOT measuring the temperature of that far away wall, but rather the general air temperature a few feet in front of you, and no infrared temp gun is very good at measuring empty air ambient temperatures.


I need a temp gun with a laser. Why do you boneheads not have a laser gun?

Look, number one, we are not boneheads!

Number two, for the RC hobby, is a laser REALLY necessary?

Certainly a laser looks mighty cool, but if you want "cool" get a laser pointer pen. Wait, that isn't really cool either. Anyway, back to the RC use. When you are temping out your RC car, something like the Nitro engine, you are trying to hit a very small spot to get your highest temp reading.

Laser sightings for temp guns are meant to measure "spot on" from about a foot away. That is MUCH FARTHER than you are likely to shoot for an RC application. When you shoot up close with a laser temp gun, the "throw" of the laser is going to be WAY OFF, and your actual temperature reading point (at a distance of two inches or less) is going to be an inch or more BELOW the laser spot! What is the point of that?

When using your temp gun for an RC application, just hold the button down, pass the gun over the engine head a few times (or whatever the target is) and look for your highest reading. No laser is necessary for that, and no temp gun has a laser that is going to help you "spot focus" from such a close distance.
At Pro Exotics, we have a "reference" Raytek temp gun with a laser. In fact is has multiple lasers, and they come together into one spot when you are at the "ideal" measuring distance. It is at least a foot away from the actual spot. We use it primarily to reference check our Pro Exotics Temp Guns, and they are spot on, every time.

Lasers? Lasers? We don't need no stinkin Lasers!!
