Fisher F75 Metal Detector Overview
The Fisher F75 runs at 13 kHz with VLF induction balance technology, and Fisher lists it for coin shooting, relic hunting, gold prospecting, cache hunting, shallow water and dry sand beach hunting. Search modes are Discrimination, Motion All-Metal and Static All-Metal, with notch discrimination and a 0 to 99 numeric target ID on a backlit LCD with multi-tone audio. FeTone sets iron audio to Off, Low, Medium or High. Ground balance is FASTGRAB automatic with manual override, and DST suppresses electrical interference. Sensitivity adjusts from 1 to 99 in two stages, 1 to 29 (low gain) and 30 to 99 (high gain), and the trigger-activated pinpoint uses variable-pitch audio with a depth readout. The 11 inch BiAxial DD searchcoil is waterproof. The control box is not waterproof and is not submersible, so keep it out of the rain. The F75 weighs 3.5 lb (1.6 kg), runs about 40 hours on four AA batteries, takes headphones with a 1/4 inch plug and carries a 2-year Fisher warranty. First Texas builds it in the USA.
Fisher F75 vs F75 LTD: Which Should You Buy?
The standard Fisher F75 and the Fisher F75 LTD share the 13 kHz platform, DST, FASTGRAB ground balance, FeTone, the 0 to 99 target ID, the trigger pinpoint and four AA batteries. The F75 LTD adds two search modes: Boost Mode, which Fisher says adds detection depth and sensitivity, and Cache Locating Mode. It comes with both the 11 inch coil and a 5 inch coil for tight, trashy spots, while the standard F75 comes with the 11 inch BiAxial DD coil.
If you hunt coins and relics in mixed ground and want the core F75 controls, the standard F75 covers it. If you search for deep caches or want a small coil for iron-packed home sites from day one, we recommend the F75 LTD. Our F75 collection also has the Fisher F75+ with F-Pulse pinpointer and The Digger and an F75 bundle with headphones, a battery charger and batteries; see each listing for what is in the box.
Fisher F75, Best For:
- Relic hunters on iron-heavy sites who want FeTone and a 0 to 99 target ID
- Coin shooting near power lines, where DST helps keep the threshold stable
- Mineralized ground, where FASTGRAB re-balances when you push the trigger forward
Fisher F75 LTD, Best For:
- Cache hunters who want Cache Locating Mode
- Hunters who want Boost Mode, which Fisher says adds depth and sensitivity
- Trashy home sites, with the 5 inch coil in the box
Key Features That Matter in the Field
FASTGRAB ground balance is trigger-actuated, so when the soil changes across a field you push the trigger forward to re-balance and keep hunting, and manual override lets you fine-tune it. DST is the control to reach for at a club hunt or near power lines, where it suppresses electrical interference. FeTone has four levels, so on an iron-heavy site you can keep iron audible at Low or Medium and still hear a good target come through. The 0 to 99 numeric target ID with multi-tone audio lets you learn your local targets, and notch discrimination drops the ones you keep digging as trash. On trash-laden ground, the FA (Fast Process) setting gives each target a shorter audio response, which Fisher says improves target separation. The Fe3O4 bar graph and the ground balance reading can be used together to map the soils of a site. Motion All-Metal hears every metal target while you sweep, and Static All-Metal and the trigger pinpoint help you size up and center a target before you dig. With sensitivity from 1 to 99, we recommend setting it where the F75 runs quietly rather than at maximum.
Where the Fisher F75 Works Best and Its Limits
The F75 is at home on relic sites, farm fields, old home sites, parks and dry sand beaches, and Fisher also lists it for gold prospecting and shallow water. The waterproof coil can go into shallow water, but the control box is not waterproof, so keep it out of the water and out of heavy rain. Fisher lists dry sand beaches, not wet salt sand, so for saltwater beaches see our beach metal detectors. At 3.5 lb (1.6 kg), the F75 is heavier than the 2.3 lb (1.04 kg) F44. For more iron discrimination on small targets, the 19 kHz Fisher F19 has a 40-point iron discrimination scale.
Coils and Accessories That Fit the Fisher F75
The F75 shares its coils with the Fisher F70. In this collection, the Fisher 11 inch DD Bi-Axial coil is the stock size as a spare, the Fisher 10 inch DD white elliptical coil trims the footprint for trashy ground, and the Fisher 10 inch black elliptical coil is a concentric option. We recommend a DD coil for mineralized or iron-heavy ground. For the shaft, the Fisher 26.5 inch replacement lower rod fits the F75, and the Anderson 12 inch carbon fiber lower rod is for detectors fitted with an Anderson shaft. The F75 takes headphones with a 1/4 inch plug, such as the DetectorPro Black Widow headphones. The Fisher F75 digital manual is a free download.
