Aproca Hard Carry Travel Case Compatible with Stud Finder Sensor Wall Scanner

this is the electronic stud finder I've already installed the 9 volt battery that it came with and I've just been testing it I made my garage and my garage does not have finished walls so we can kind of see where the where the builders had put in nails and plaster on to the sheetrock here so I'm gonna turn this on and I'm just gonna walk you through a little demonstration and how it actually worked in my garage there's a button a power button right here okay and then over on the side it has the Scan button so I'm gonna go ahead and press the power button on and at first I started with the 1/2 inch stud here and I'm gonna press this so once you press this it does a calibration with all those and then it becomes it becomes on and ready the lightning bolt that you see at the top is the AC live wire scan it always scans on this device so regardless of which one of these modes that you choos
