Review on Tavool 4-in-1 Electronic Stud Sensor Beam Finder - Wall Scanner for Center Finding with LCD Display - Detects Wood, AC Wire, Metal Studs, and Joists by Dan Cramer

I found a Stud Finder the other day and it was on sale with great reviews so why not?! It arrived an hour ago. Too bad they didn't mention that the 9V battery was NOT included; but that's easy to fix. I read the instructions (which I usually follow because I'm anal and a former Naval Flight Officer) and it worked HOW BENEFICIALLY! I find the instructions very useful to read, the machine's performance needs to be accurate, and having multiple settings for fine vise, deep metal-wood vise, and electric ALL-IN-ONE is really helpful. Calibrating the device before use is important, but quick. Definitely a great purchase compared to previous ones I've had.
