Fisher has designed the Fisher F5-11DD metal detector with a 7.8 kHz operating frequency and the hot Fisher 11" DD Coil which will make it a great detector for coin, jewelry, relic and even gold prospecting. The Fisher F5 metal detector has advanced software based motion discrimination with notch for searching trashy areas. The Fisher F5 metal detector has a brilliant user interface. The Fisher F5 metal detector is also spectacular in another area... user information! The Fisher F5 metal detector feeds the hunter with important data in real time.
The Fisher F5-11DD Metal Detector Features:
Fisher 11" DD Coil 7.8 kHz frequency - good for coin shooting, relic hunting, and casual gold prospecting Frequency shift for eliminating electrical interference and crosstalk Advanced software-based motion discrimination with notch for searching trashy areas All metals auto tune mode for deep-searching in non-trashy areas Visual target ID by category and 0-99 indication, both discrimination and auto tune modes Target ID confidence bar graph High-resolution manual ground balance with continuous ground balance readout Ground balance range goes all the way to salt Continuous display of ground mineral concentration and phase Push-button static pinpoint with variable audio pitch and visual depth reading Independent gain and threshold knobs provide complete control over sensitivity Standard 10 inch elliptical concentric open-center searchcoil. Other coils available separately Two 9-volt alkaline batteries last approximately 40 hours
The variable tone pinpoint system distinguishes between different metals, like nails, pennies, quarters and bottle caps for a more accurate target identification to maximize your digging efforts. The Fisher F5 Metal Detectors comes with a manual ground balancing option to cancel unwanted signals that usually come from natural ground minerals. Easy-to-use control knobs, Elliptical search coil, Requires two 9-volt batteries (not included).
Manufacturer's five-year limited warranty.
