Stanley’s new FatMax Stud Sensor 300 has features that finish carpenters should appreciate. In addition to finding studs 11/2 inches in from the surface, it detects AC current up to 2 inches in and metal up to 3 inches in. It has an easy-to-read backlit LCD screen, and the sensor indicates the center of the stud. A V-shaped channel at the nose of the tool helps with the accuracy of the marks. Soft grips are easy on the hands. ¦ Price: $35. 800-262-2161. stanleytools.com.
