The Aavix AGT310 Smart Metal Detector boasts advanced features that allow you to detect metal targets in even the hardest places. It allows you to selectively target specific metals by ignoring objects that aren't of interest to you. The full digital display, located conveniently in the extendable handle, allows you to see the exact depth of the metal. Additionally, its lightweight construction and extendable handle make it quite easy to carry around without straining yourself while you search. The 3.5 mm headphone jack allows you to listen to the alarm sounds as you get closer to your target, and the volume can be adjusted so that you don't miss anything. Unlike most traditional metal detectors, this one tunes itself automatically, so you can search with ease, and without worrying about accidentally setting the wrong sensitivity. The lightweight, heavy-duty construction also features an IPX7 waterproof rating, allowing you to search wherever you need to, in and out of the water, for maximum versatility. Capable of working in almost all weather conditions, the Aavix AGT310 Smart Metal Detector is the perfect choice for the best performance.
