Ryobi Whole Stud Detector

This new “whole stud” finder from Ryobi gives you a more complete picture of the stuff you’re trying to hit. The EFS 5000 uses a series of LED’s along the top to show you where the entire stud is. It also features a marker for the center of the stud: an LED lights up when it’s centered and with the press of a button you can leave a small dimple to mark it. Powered by a singe AA battery.
