Fisher F22 Weatherproof Metal Detector with 9-Inch Waterproof Coil

The Fisher F22 is a 7.69 kHz VLF metal detector built with a weatherproof control housing, 9-inch concentric waterproof coil, and four preset hunt modes that let first-time detectorists and experienced coin shooters turn on and start swinging in parks, fields, and dry beach sand. Operating at 2.3 pounds with 9-segment visual target ID and 4-tone audio feedback, the F22 bridges the gap between Fisher's entry-level F11 and the ground-balancing F44, offering notch discrimination and adjustable iron audio in a lightweight platform that runs 25 to 30 hours on two AA alkaline batteries. We carry it for detectorists who hunt in inclement weather, need a weatherproof backup machine, or want a reliable coin and jewelry detector at a sub-$250 price point without sacrificing Fisher's USA-manufactured build quality.

Weatherproof VLF Performance in Wet Conditions and Mineralized Dry Sand

Parks and Lawns After Rain

The F22's weatherproof control box and sealed coil connector handle detecting in wet grass, light rain, and morning dew without requiring a rain cover or protective housing. The 7.69 kHz operating frequency stays stable in damp topsoil, and the adjustable iron audio lets us silence rusty nails and bottle caps while keeping the detector chirping on typical coin-sized targets at moderate depths. Four preset modes, Jewelry, Coin, Artifact, and Custom, eliminate the need to manually notch out target categories on the first hunt.

Dry Beach Sand and Picnic Areas

The 9-inch concentric coil covers ground faster than the 7-inch coil on the F11, and the elliptical footprint punches through dry sand to pull rings, coins, and lost keys from moderate depths depending on target size. The F22 is not rated for saltwater immersion or wet-sand hunting, only the coil is waterproof, not the control housing, but it handles dry-sand tot lots, volleyball courts, and picnic blanket zones where jewelry and pocket spill concentrate. Pinpoint mode with depth readout tightens the target location for precise digging before we dig.

Farm Fields and Old Homesteads

The F22 runs a preset ground balance tuned for moderate mineralization, which covers most Midwestern farm fields, East Coast colonial sites, and low-mineral Western prairie ground. In iron-heavy relic sites, the adjustable iron audio (Fe-Tone) lets us reduce or mute the low bass tone that signals square nails and horseshoes, so high-conductors like large cents, buttons, and buckles stay audible without constant iron chatter. The 9-segment visual target ID and numeric 1-99 scale give two layers of confirmation before we commit to a plug.

Lightweight Ergonomics and Turn-On-And-Go Operation for All-Day Hunts

• 2.3-pound operational weight reduces wrist and shoulder fatigue on four-hour park sessions and full-day relic hunts: lighter than most mid-tier detectors and manageable for younger detectorists.
• Four preset hunt modes eliminate manual discrimination setup: Coin mode silences iron and foil, Jewelry mode opens the acceptance window for gold rings and chains, Artifact mode passes relics in the mid-conductive range.
• 9-segment visual target ID paired with 4-tone audio confirms target type twice before digging: ferrous targets trigger a low bass tone and light the iron icon, mid-conductors (nickels, pull-tabs) sound a medium tone, high-conductors (silver, copper) produce a high bell tone.
• Pinpoint mode with numeric depth indicator zeroes in on the target's exact location and estimates burial depth, faster than sweeping in motion mode for shallow coins and small jewelry.
• 25 to 30 hours of battery life on two AA alkaline batteries covers six to eight full detecting sessions before a battery swap, and the non-volatile memory saves sensitivity, volume, and mode settings between power cycles.
