what's your opinion on them? should i get one, or just stick with the trusty ol sling?
Get one...according to Dice it should be a UEI...
lol, i'll probably get one but, no offense dice, it WON'T be a UEI!
Extech RH390. Had it for years, very happy with it. I'm not a hvac contractor, I just use it to check attics, basements, crawls, etc. One of the most accurate pieces I could find at a decent price. Don't forget to calibrate once in a while.
