Metal detector FinePower GMD221 ‒ a ground, low-frequency instrument (VLF) for locating metal objects in soil and bodies of water. The waterproof coil has a hermetically sealed housing, which allows searching for metal items in water. For ease of operation, the device design includes an armrest. This makes it comfortable to grip the handle, fixing the elbow. It will relieve tension from the neck and arm muscles, allowing you not to feel fatigue even during long hours of work with the tool.
FinePower GMD221 uses a concentric coil and searches for items at a depth of 50 cm. The metal detector operates on a 9V battery. This makes it mobile and allows taking the instrument to different places. The audible signal informs the user of a detected metal object. If you do not want the signal to irritate others and be heard only by you, you can connect headphones. For this, the body contains a special jack.
