General Tools Magnetic Tester

The General Tools AMY6 Magnetic Tester lets you quickly and effectively find magnetic fields and determine whether or not an object is magnetic. This tester features two colored LED indicators that indicate which magnetic pole you have found. The red LED lights up for north and green for south, with a loud buzzer alert that sounds when the magnet poles have been located. The AMY6 Magnetic Tester comes with a pocket clip that allows it to be easily carried with you into the field. It runs on four LR44 batteries, which are included.
