Review on Enhance Accuracy with the ProSensor T13 Professional Stud Finder: 13-Sensors for Unparalleled Precision by Ryan Reed

I've had a few nail finders over the years and even started "tapping" drywall to find the nail my dad taught me. But by far this is the best spike finder I have ever used and owned. It was really accurate. I even tested it in my basement where it is unfinished except for one section where I only have a sheet of drywall around. Another additional feature I would like to have is metal detection. I thought it recognized "plumbing pipes" too. If I hadn't seen it was a pipe and thought it was a hairpin, it could have ended very badly. This would be the only feature improvement I would wish for. Also, it runs on 2 AA batteries. I don't always have a bunch of 9 volt batteries, all other devices I've had have used 9 volt batteries. I would have to retrieve it if I found the ones I had were dead or to temporarily clear the smoke detector.
