If the Franklin Sensors ProSensor M210 sounds appealing to you but the price tag is a little too hefty, then a more than worthy alternative comes from Hart Tools, which can be found at Walmart. Hart makes a Professional Stud Finder that is the same concept as the one from Franklin Sensors, but instead of 13 sensors for detection, it has nine, which is still quite a lot. It can detect studs up to 1.5 inches behind your wall, which is just a tad shorter than the M210’s 1.7 inches, but that is still more than the 3/4 inch detection of the Craftsman.
The Hart Professional Stud Finder also indicates that a live electrical wire has been detected, but it lacks the same precision of displaying exactly where that wire is as the M210. Retailing for just under $28, Hart has made a good budget alternative to the more expensive M210. So, what it lacks in complete precision it more than makes up for in its pricing.
