The Fisher F75: The Premier Relic & High-Performance Detector
The F75 built its reputation on relic ground — the trashy, iron-laced, heavily mineralized sites where lesser detectors fall apart. Its 13 kHz operating frequency, double-filter discrimination, and fast process mode give it the target separation to pull a good signal out from between the nails, while trigger-actuated FASTGRAB ground balance lets you re-balance on the fly as soil changes. Digital Shielding Technology (DST) suppresses electrical interference for a stable threshold, the magnetic mineralization bar graph tells you how hot the ground is, and trigger-actuated pinpoint with variable audio pitch puts you right on the target. It's also famously light and well balanced, so all of that capability doesn't cost you a sore arm at the end of a long hunt. Coins, relics, beach, even gold prospecting — the F75 does it all, which is why it's been a benchmark machine for years. It's the high-performance step up from the all-purpose F44, and a natural fit alongside our full relic & treasure detectors.

Fisher F75 vs F75 LTD (Special Edition Black)
Both run the same high-performance F75 core, so the choice is about how much you want to push it. The standard F75 ships with the 11″ DD waterproof coil and gives you the full F75 feature set — DST, FA, FASTGRAB, trigger pinpoint, and the mineralization readout. The F75 LTD Special Edition (Black) adds two more search processes — Boost, which substantially increases depth in most conditions, and Cache, designed to find large, deep objects — and ships with both the 11″ DD and a 5″ DD coil for tight, trashy spots. If you hunt deep relics, caches, or simply want every process Fisher offers on this platform, the LTD is the one; if you want the proven F75 performance at a lower entry, the standard is all the detector most hunters will ever need. Prefer a complete kit? The F75+ bundle pairs the detector with an F-Pulse pinpointer and a digging tool.
Coils for the Fisher F75 (and F70)
The F75 shares its coil mount with the older Fisher F70, so there's a deep coil selection. The 11″ DD bi-axial coil is the do-everything default for depth and separation, the 10″ DD elliptical coil trims weight and tightens response, and the 10″ elliptical coil is another proven option. Keep a spare 26.5″ lower rod or the lighter Anderson carbon lower rod on hand, and grab the free Fisher F75 digital manual. Still running an F70? These coils fit it too — and when you're ready to upgrade, the F75 is the current high-performance Fisher.
Fisher F75 FAQs
What's the difference between the Fisher F75 and the F75 LTD?
They share the same high-performance core. The F75 LTD Special Edition (Black) adds two extra search processes — Boost for more depth and Cache for large, deep targets — and ships with both an 11-inch and a 5-inch DD coil. The standard F75 ships with the 11-inch DD coil and the full standard feature set. Choose the LTD for maximum depth and versatility; the standard for proven F75 performance at a lower price.
Is the Fisher F75 good for relic hunting?
Yes — it's widely considered one of the premier relic detectors made. Its 13 kHz frequency, fast process mode, double-filter discrimination, and FASTGRAB ground balance are built to separate good targets from iron and handle the mineralized, trashy ground that relic sites are known for, all in a light, well-balanced package for long hunts.
Is the Fisher F75 waterproof?
The F75's control housing is weather-resistant but not submersible, while its DD search coil is waterproof — so you can hunt in the rain and work wet ground and shallow water at the coil, but don't submerge the whole detector. For dedicated underwater detecting, choose a fully waterproof machine.
What coils fit the Fisher F75?
The F75 shares coils with the Fisher F70, including the 11-inch DD bi-axial and 10-inch DD elliptical coils, plus the 5-inch DD coil for tight, trashy spots (included with the LTD). That shared lineup gives the F75 a wide range of coils for different sites, all stocked here.
How does the Fisher F75 compare to the F44?
They're different tiers. The F44 is a simple, weatherproof all-purpose detector for everyday coin, jewelry, and relic hunting; the F75 is a high-performance, advanced machine built for serious relic hunting and deep, mineralized, trashy ground, with far more processing power, ground-balance control, and depth. Choose the F44 for value and simplicity, the F75 when you want maximum capability.
Where can I find the Fisher F75 manual?
