F4

The Fisher F4 metal detector features a waterproof 11" open frame search coil designed with "Double D" technology to ensure maximum depth and exeptional signal strength. Meanwhile the big digital face plate and easy-to-see push buttons put even the most advanced features at your fingers! A 11 segment digital target id system will help you SEE your target BEFORE you begin to dig - don't bother with pulltabs when you can locate coins and rings! Working at a 5.9kHz frequency, the Fisher F4 boasts FOUR search modes created to help you sniff out treasure in any ground conditions! Search with "Auto Tune" for all metals, use "Discrimination" mode to manually tune out the metals you don't wish to find, utilize the "pinpoint" feature to hone in on the smallest treasures and know exactly where to dig, or use "notch discrimination" to focus on gold, silver and other valuable metals!
