Questions?? Temp. Guns

Was just wondering if anyone had suggestions on a good temp gun to buy? I would like a nice one but don't want to spend more money then I have to. Maybe some of you guys have exsperience in a site to pick one up as well. Thanks

I have had one of these styles for years, works great...I'm sure if you dig around you might find one for cheaper, but does the job. Just an example link:

Temps in R/C are all for reference. A cheapo one like the one listed above or a duratrax one you should be able to get at any hobby shop for around $25 should be all you need. My buddy had a $300 exergen gun that works awsome but truthfully if the temp was off by 5 deg it wouldn't really matter for temping electric or nitro motors.

I've got a little IR temp gun not to far off from what y2kgtp and Casper describe, little $25 unit.

When I bought it my Old Man and I stood next to each other with his much more expensive temp gun he uses for working on 1:1 cars and started pointing at the same stuff, if my $25 dealy was off it wasn't by more than a couple degrees.

What is nice about mine is it has a MAX setting. Once you enter MAX mode you can just hold the button down and wave it around whatever you're temping and the display will only update if it finds a hotter temperature than what's currently listed, so it doesn't much matter if I don't point it at exactly the same spot after each run.

IMO the only reason to get anything more expensive than one of these is if you want the laser pointer.

Like I said. +/- 5 deg is fine for what we do.

Go to harborfreight.com Search for temp gun or part # 93983-4VGA

Looks a lot like the duratrax one, only a lot less.

+1 on that notion. A cheapo Duratrax ones are just fine for RC applications. A highly accurate ones aren't really necessary for hobby. They are really made for application that requires a highly accurate measurement. Even then, you can't beat a thermocoupler since you can directly couple the heat (metal to metal).

To keep our toys running, a +/- 5C error wouldn't really hurt since you should back off from the absolute maximum with more margin then the temp gun's error margin...

If you don't mind directly coupling, many cheap multimeters come with thermo couplers nowadays. I use mine that came with my Fluke meter... Really works well with functions such as max hold...
