Fisher F70 Metal Detector with 10" Waterproof Search Coil

Fisher F70 Metal Detector with 10" Waterproof Search Coil

The Fisher F70 is a lightweight, versatile metal detector built for coin shooting, jewelry hunting, relic hunting, and gold prospecting. Its fast response, detailed target information, computerized ground balancing, and customizable controls make it a capable choice for both experienced detectorists and ambitious beginners.

Operating at a versatile 13 kHz frequency, the F70 provides strong sensitivity across a broad range of targets. The included waterproof 9¾-inch concentric search coil—commonly marketed as a 10-inch coil—offers an excellent balance of detection depth, ground coverage, accurate target identification, and precise pinpointing.

Accurate Target Identification

The F70 displays probable target conductivity on a numerical scale from 0–99. Visual target categories and a target-confidence indicator provide additional information, helping you evaluate signals and make more informed digging decisions.

Adjustable discrimination and notch controls allow unwanted target ranges to be rejected, while multiple audio-tone options help identify probable targets by sound.

GroundGrab Ground Balancing

GroundGrab measures the soil’s magnetic properties and automatically adjusts the detector to reduce interference from ground minerals. Manual adjustment is also available for operators who want to fine-tune performance.

The wide ground-balance range extends from ferrite-rich soil through conductive salt conditions, giving the F70 the flexibility to operate across many environments.

Two Search Modes

Discrimination Mode provides adjustable target rejection, notch control, tone selection, sensitivity, threshold, and recovery-speed settings.

Autotune Mode provides a responsive all-metal search mode for maximum sensitivity and efficient ground coverage.

Two programmable memory slots let you save and recall preferred settings or quickly switch between different hunting configurations.

10" Waterproof Concentric Search Coil

The included open-frame concentric coil measures approximately 9¾ inches and is commonly described as a 10-inch search coil. Its focused detection field provides dependable target identification and accurate pinpointing, while the open construction helps keep the detector light and easy to swing.

The search coil is waterproof and may be submerged in wet grass, mud, freshwater, or shallow water. The F70 control housing is not waterproof and must remain dry.
