A consideration when choosing a temp gun is the distance / spot ratio. Many of the low cost guns have ratios of 4:1 or so. That means that a one foot distance the spot is 3 inches in diameter, not very selective. The better guns are generally 8:1 ($60-70) and there are 12:1 models (in the $125 range).

Hi Earl,
I'm using the $39 Radio Shack temp gun, don't know what the dist/spot ratio is but since I shoot the temps from ~ 1" to 4" I'm guessing it doesn't much matter.
Besides, it's nice and small and it can fit in your pocket (it's also occasionally on sale for $29!).
Thx, Jerry
