This is the famous Exergen DX501 Infra Red Temperature Gun. This is the most accurate temperature gun you can buy, and is what most of the top drivers use to measure the temperature of their engines. This temp gun is the most accurate you can get, so if you want the best, this is it!

Note that like all Infra Red temperature guns that have an exposed tip, it is always a good idea to keep the end of the gun clean. If you get dirt or debris in the end of the gun it can affect the readings, so spray a little denatured alchohol on the end of the gun and blow it off with an air compressor. Also make sure the batteries are fresh, as dead batteries will also make a temperature gun measure incorrectly.

The DX501 temperature gun can also be re-programmed to display the temperature in Celcius instead of the default setting of Farenheit.

NOTE: If your temperature gun starts to read values that appear to be off, it probably means the battery is going flat. Please replace the battery, and the readings should be accurate again. Also make sure the tip is clean, and if it gets dirty, clean it with an alcohol cleaner like Denatured Alcohol and an air compressor.

Sorry not knocking the tool but $259 come on thats insane!!!!!! Whoever reads this post u are way better off to go to a tool maker like snap on and do ur tool shopping!! Way bigger selection with life time warr. no hassel the rc tools are way over priced items that only make people think they need cause its sold aiming at the hobby! Do ur homework and find a place that sells tools even call snap on they can even make a stop at ur house with the tool truck if u make a decent order or they will at least meet up with u at one of their stops.......

This is the best Temp Gun money can buy for this hobby.Its 260 dollars but its better than getting an off reading and over heating you 300 or 400 dollar motor.

Best temp. gun out there. If your gonna spend the money on a good engine then this is a absolute for your pit bag....Other temp guns just don't get the accurate reading needed...imo. and if you see a guy in the pit lane with one check your and his against each other at race conditions and you will see why the cost is there.
Compared my HPI tep guage to a friends Exergen, the HPI one was within 1 degree of the exergen. If you have the money to spend buy it, especially if you do alot of night racing and want the backlight. But don't buy it if you think that your temp gun is off so you need to buy this one. Compare temps with a friends exergen and find out how close your temp gun really is.

A must have. The best engine tuning tool you can have. After finding out my $40 temp gun was 20 degrees off, I bought the exergen and it was the best purchase I have made.
