    What in the world will I use a Temp Gun for?

    Pro Exotics Infrared Temp Guns have a million different uses. For the R/C car hobby, your hot uses would be engine temps, tire temps, and track temps. Electric motors can also be measured for maintaining R/C car and airplane performance. Nothing gives you the immediate feedback and reliable accuracy of an Infrared temp gun, and the Pro Exotics Temp Gun is the smallest, handiest, most affordable gun available!

    Price: $35
    Temp Range: -27.4°F to +420°F / -33°C to +220° C
    Field of View: 1:1 optics ratio
    Battery: CR2032
    Battery Life: 40 hours continuous (auto off after 15 seconds)
    Accuracy: ±2%
    Weight: 32 grams with battery
    Dimensions: 18 x 37 x 68mm

    The TempGun comes complete with case and a spare battery. You simply point the device near an object and press the button. The TempGun will capture, hold, and display the highest temperature measured. These infrared temperature recording guns are an indispensable tool for the R/C hobby.

    Temp Guns are an amazing tool that help to keep cars, trucks, boats, planes, and helicopters running at peak performance. The three main temperature concerns for the R/C car hobbyist and racer are engine head temperatures, tire surface temperatures, and track surface temperatures. For awesome 3D e-flight applications, monitoring your electric motor temperature is critical for maintaining performance and longevity of your investment in expensive brushless motors. Nothing is quicker or more accurate than a handheld infrared Temp Gun, and now, Pro Exotics (PE) Temp Guns are available at a price every hobbyist can afford. Along with their extremely convenient and portable size, these PE Temp Guns also feature an incredibly handy Min/Max reading.

    With the progress of infrared technology, production costs have crept lower and lower, but without sacrificing accuracy and quality. Our PE Temp Guns shoot the same temperature readings as our $400 Raytek guns, so hobbyists, and R/C users alike, can use the PE Temp Guns with confidence and assurance that they are getting the most out of their tool.

    How do I use the Pro Exotics Temp Gun to measure my R/C engine temps?
    When temping out the engine of your Nitro car, you are looking for the highest current reading. That highest reading is typically going to come from your glow plug, and you can usually hit it from right over the top of your engine. Hold the "measure" button down on your PE Temp Gun, and pass it over the top of the engine. Get right up on the engine, so that you are just about touching the head. Note the highest reading that you get, that is the number you are looking for.
    With a moderately warm Nitro engine, you are likely to see temps in the 180-210°F range. With a car that has been running hard for a while, you will start to see the engine creep north of 230 or 240°F. Get to know the parameters of your own car and engine to fully understand what will be the best operational temps for your individual situation, whether it be backyard bashing or serious racing.

    As a note, also consider using the "Max" feature of the Pro Exotics Temp Gun. Hit the "measure" once to turn the gun on, and then hit the mode button twice to enter the "Max" mode. This way, as you hold down the measure button and pass over your engine, the PE Temp Gun will grab the HIGHEST reading and hold it until it sees something even hotter.

    Why doesn't the TempGun have a laser?
    For the RC hobby, is a laser REALLY necessary?

    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 R/C 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 R/C application, just hold the button down, pass the gun over the engine head a few times 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. For measuring the accurate temperature of electric brushless motors, simply point the Temp Gun near a line-of-sight opening in the cowl.

    At Pro Exotics, they use a "reference" Raytek temperature 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.

    Pro Exotics guarantees the accuracy and durability of these affordable Temp Guns as they are confident you will absolutely fall in love with it! Temp Guns are also great for use with Reptiles, HVAC, Food Service, Facility Maintenance, Tuner Cars, and more!
