I've got one that's 4 years old. It's the first detector to come out of the truck. Have replaced the refer sensor once, and have gone through a lot of batteries. I've experienced no problems. Wish I could say the same for the Dtek select, and the CPS. My H-10 is used to verify if the Bach. doesn't pick it up or does weird things. I wouldn't spend 3 bills on a new one however,,,,,,,,,
One way to outthink people is to make them think you think. They'll think you're not really thinking what you're trying to get them to think you think...........
It seems like i have used or purchased every leak detector there is at one time or another. The H-10 is simply superior to them all. IMHO. I purchased mine slightly used on Ebay for about what your looking to spend.
I used an H 10 pm battery Loved it. had it side by side with a DTEK and it lead me straight to the source and the DTEC guy was amazed. It is spendy but it is the Best. hands down. this was supermarket refrigeration mind you.
