Digging for treasure takes more accuracy than you think. With the Minelab PRO-FIND 40 Pinpointer, you'll know exactly where to dig to find the hidden coin, ring, or gold you've been working for. With its 5-level sensitivity control and button-activated rapid re-tune, you can quickly fine tune for maximum depth and minimal noise to match with your ground conditions. Built-in DIF technology dramatically reduces interference with an operating detector when your Minelab PRO-FIND 40 Pinpointer is switched off. This metal detector accessory is fully waterproof to 10'. It has both audio and vibrations that intensify when you near your target. It even has 2 differing tones to help you identify the difference between ferrous junk from non-ferrous and more desirable items. The PRO-FIND 40 Pinpointer is made to be highly visible, and it comes equipped with a lost-alarm feature, which both make it easy to locate if you put it down and walk away. It also features an LED flashlight that helps you spot your target while digging. Convenient holster and lanyard included. Runs on a 9V PP3 battery (included).
