For the “beep and dig” types, get started with six preset programs (Coin and Jewelry, All-Metal, Beach, Prospecting, Relic, and High Trash) and easy-to-access threshold, gain, ground, and pinpoint modes. Pressing the Options button accesses more controls, with user-adjustable Volume, Threshold, Depth Units, Backlight Level, Frequency Shift, Salt Track, Program, Self-Adjusting Threshold, Iron Grunt, VCO, Reject Volume, and Discrimination Mask.
The included 9.5″ Concentric coil makes pinpointing targets easy, and offers incredible depth in mild to moderate soils (optional accessory coils include all Sport coils). Due to its 14kHz operating frequency, the MX7 excels at locating smaller targets, such as hammered silver coins and small gold earrings.
The MX7 features a robust transmit circuit compared to other models in its price range, and is capable of extreme depths on coin-sized objects. As a relic-recovery device the included Reject Volume can easily identify iron patches as well as help unmask very deep or hidden targets in stubborn sites.
A high-powered onboard speaker, rear-mounted 1/4″ headphone jack, and large, backlit display complete the design, complimented by the high-visibility black and orange color scheme.
