Description
The recalled stud sensor models include the Stanley® Stud Sensor 200 and Stanley® FatMax® Stud Sensor 400 with model numbers 77-720 and 77-730. The model number is located in a slide-out reference guide found in the base of the sensor's handle. The sensors are made of black plastic with a wide yellow stripe down the center. "Stanley" or "FatMax" are printed on the front of the product. A date code is printed on the inside of the battery cover. Affected sensors have date codes that do not begin with the letter "R."
