The Fisher F75 has been discontinued
It is no longer sold new on Amazon. We've kept this review online for reference — the Fisher F75 still turns up on the used market, and the specs, pros and cons below are just as relevant when you're judging a secondhand listing. We're not recommending a substitute, because no current model is a like-for-like replacement.
Last listed at $419.00 before it was discontinued. That figure is historical, not a current price.
Fisher F75Complete Review & Field Test 2026
Coil-only waterproof (Coil only) — the searchcoil can be submerged, but the control box must stay dry. It's not a diving detector, but it's fine for wet sand, rain, and shallow streams. See the full waterproofing FAQ
The F75 earned its reputation among relic hunters with fast target response and excellent iron separation. The dual-filter discrimination system helps pull good targets from iron-infested sites. Lightweight at 3.5 lbs with exceptional balance, it remains comfortable during long hunts on Civil War sites and old homesteads.
Key Features:
- 13 kHz frequency
- DST (Digital Shielding Technology)

Technical Specifications
In-Depth Field Performance
Detection Depth & Coverage
In field testing, the Fisher F75 demonstrates consistent target acquisition across various soil types. The 11" DD biaxial provides excellent ground coverage while maintaining sensitivity to smaller targets. With a maximum detection depth of 13-15" (coin), it performs admirably for relics and coins hunting. Recovery speed between targets is fast enough for trashy sites, making it suitable for recreational hunting.
Target ID & Discrimination
Target identification on the Fisher F75 uses Multiple options to differentiate between valuable finds and junk. The 4 + Process modes search modes provide flexibility for different hunting scenarios. Audio feedback is clear and responsive, helping you make quick dig decisions. The Speaker + headphone jack delivers clear tones even in noisy outdoor environments.
Technology & Ground Handling
Fisher equipped the Fisher F75 with 13 kHz technology, which is optimized for detecting a wide range of targets from gold jewelry to silver coins. The Manual + Ground Grab system gives experienced users full control over mineralization compensation. The submersible coil allows hunting in wet grass, shallow streams, and rainy conditions.
Build Quality & Ergonomics
Weighing 3.5 lbs (1.59 kg), the Fisher F75 has a solid feel that inspires confidence, though longer sessions may require breaks. The 43" to 52" adjustable accommodates users of different heights. Build quality is excellent—made in the USA with quality materials. 30-40 hours means less worry about power during full-day hunts.
Settings & Modes Guide
Choosing a Search Mode
The Fisher F75 offers 4 + Process modes search modes. For relic hunting or coin hunting in parks and yards, start with the preset closest to that target type — it pre-loads discrimination and tone breaks tuned for it — then fine-tune discrimination and sensitivity from there as you learn the site.
Discrimination Setup
Discrimination on the Fisher F75 runs on Multiple options. Start conservative: reject only signals you've confirmed are iron or foil, and dig everything else until the site teaches you what junk sounds like here.
Ground Balance
Ground balance on the Fisher F75 is manual (Manual + Ground Grab). Ground it out before every hunt — raise and lower the coil over bare ground until the threshold stops changing, then lock the value in — and re-balance whenever the soil changes, such as moving from dry sand to wet sand or from a yard into mineralized clay.
Sensitivity & Mineralization
The Fisher F75 runs at 13 kHz. In average, low-mineralization soil, sensitivity can run near the maximum stable threshold for the deepest signal. In mineralized ground — red clay, black sand, or salt-contaminated soil — back sensitivity down until the false chatter settles, then re-check your ground balance.
Pros & Cons
- Legendary speed and separation
- Boost mode adds depth
- DST reduces interference
- Incredible battery life
- 5-year warranty
- Not waterproof (coil only)
- Older technology (single freq)
- Learning curve for optimal use
Dedicated coin shooters who prioritize target ID accuracy, fast recovery speed, and reliable discrimination in trashy areas.
Those who plan to hunt exclusively in saltwater or need maximum depth. Consider upgrading to a waterproof model with manual ground balance.
Things to Know Before You Buy
Not waterproof (coil only)
Keep the control box out of standing water regardless of what the coil itself can handle.
Older technology (single freq)
Something worth weighing before you buy, based on real owner feedback.
Learning curve for optimal use
Budget a few outings to get comfortable before judging the detector on its full potential.

Frequently Asked Questions
In optimal low-mineralized soil, the Fisher F75 can detect a quarter-sized coin at 13-15" (coin). Larger objects like relics and caches can be detected at greater depths. In highly mineralized ground, expect 15-20% reduction in depth. Actual results depend on soil conditions, target size, and discrimination settings.
The Fisher F75 is designed for intermediate detectorists who want more control and features. Beginners can use it but may need time to learn the advanced settings. Consider the Fisher entry-level models if you're just starting out.
The Fisher F75 is coil-only waterproof (Coil only): the searchcoil and lower shaft can be submerged, but the control box must stay dry. This is not a diving or full-submersion detector — but it is perfectly fine for wet sand, shallow streams, light rain, and dew-covered grass. If you plan to wade in water above the shaft or work the surf zone, you'll want a fully waterproof model instead.
Start on the search mode closest to "relics" — the Fisher F75 ships with 4 + Process modes search modes, and the closest match pre-loads discrimination and tone breaks for that target type. Keep discrimination low at first so you don't skip real targets while you learn the site, and ground balance manually before you start swinging. Tighten discrimination and sensitivity once you know what the local trash sounds like.
The Fisher F75 uses Multiple options for target ID. Start with little to no discrimination so you learn what iron, foil, and pull tabs sound like in your specific soil, then notch out only the confirmed junk tones — narrow notches beat wide ones, since wide rejection zones also bury real targets.
The standard Fisher F75 package includes: the detector unit, 11" DD biaxial, coil cover, headphones, requires AA batteries (sometimes included), and user manual. Some retailers offer accessory bundles with additional coils, carrying bags, and digging tools.
Yes, Fisher provides a 5 years manufacturer warranty for the Fisher F75 in the USA through authorized dealers. As a USA-made product, service and parts are readily available. Register your detector after purchase for full warranty coverage.
The Fisher F75 at its last listed price of $419.00 competed with mid-range options like the Minelab Vanquish and Nokta Legend. Key advantages include legendary speed and separation and boost mode adds depth. However, note that not waterproof (coil only). See our comparison guides for detailed head-to-head analysis.
Final Verdict
Based on 130 reviews
The Fisher F75 is an excellent choice for dedicated coin shooters who prioritize target id accuracy, fast recovery speed, and reliable discrimination in trashy areas.. With a proven track record of 4.2-star ratings from 130 users, it delivers on its promises in the field.
At its last listed price of $419.00, the Fisher F75 sat in the mid-range segment. For intermediate hobbyists, it offers professional-level capabilities that justify the investment. The 5 years warranty applied to units bought new, and may no longer be transferable on a secondhand purchase.
Bottom Line: The Fisher F75 is no longer made or sold new on Amazon. It's still worth considering secondhand if the specs above match how you hunt — just budget for the fact that parts, coils and warranty support get harder to find on a discontinued machine.
