Law Enforcement Investigation Metal Detector


The Fisher F4 metal detector features a waterproof 11″ open frame search coil created with “Double D” technology to ensure maximum depth and incredible signal strength. Meanwhile, the large digital faceplate and easy-to-see push buttons put even the most advanced features at your fingertips!

An 11 segment digital target identification system will help you SEE your target BEFORE you start to dig – don’t bother with pull tabs when you can locate coins and rings! Operating at a 5.9kHz frequency, the Fisher F4 boasts FOUR search modes designed 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 want to detect, 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 precious metals!

The F4 features adjustable discrimination and sensitivity, and the manual ground balance will allow you to detect in virtually ANYWHERE, as you can tune out even the toughest ground mineralization.

Finally, the Fisher F4 has FOUR audio tones to help you identify targets not only by what you see on the large screen but by the type of sound you hear! A five-year warranty will ensure that you keep metal detecting with the Fisher F4 for as long as you want! This is truly another outstanding metal detector added to Fisher Metal Detectors.

This metal detector can be used for treasure hobbyists or by security/law enforcement departments.
