Minelab Equinox 800 Metal Detector w/ 6\ Coil, 15\ Coil & Pro-Find 20 Pinpointer

...Our professional metal detector kit is upgraded with DSP chip, which has higher sensitivity. In all metal mode, it can detect a depth of 10 inches, which is 2 inches deeper than other metal detectors..
【Higher Accuracy】This metal detector uses the latest integrated circuits to improve the efficiency of the chip algorithm, and will not cause the target to be lost because of your detection rate is too fast. It has a very strong anti-interference, so that it can be more precise and more efficient in the detection process..
【5 Modes of Operation】The metal detector has 5 different metal detection modes. It will be a good helper for you to find coins and treasures. ①All metal mode: 7 kinds of targets can be detected. ②DISC mode: 5 targets can be eliminated in sequence: bottle cap, foil, 5￠, pull tab, 1￠. ③Notch mode: freely discriminate against the 4 categories of foil, 5￠, pull tab, and 1￠, ignoring garbage and unwanted objects. ④Pinpoint mode: It can locate the target more accurately. ⑤ Volume mode..
【Adjustable Metal Detector】36.2" to 47.2" height adjustable valve stem is suitable for children and adults. You can enjoy detecting joy with your child at home, or pack it up for easy travel to any of your favorite treasure hunting....
