With Magnespot equipment, you can precisely determine drilling or boring points on a surface. This tool allows for through-hole drilling with maximum accuracy. It can be used on various surfaces, including ceilings, floors, and walls. The point detection operates via an electromagnetic method. The locator works by placing the transmitter on one side of the wall and the receiver on the other. The signal is detected, enabling precise marking on both sides of the wall. The locator weighs only 2.5 pounds and is powered by a 9V battery.
