Fisher F70 Coil Combo Metal Detector with 3 Waterproof Search Coils

Fisher F70 Coil Combo Metal Detector with 3 Waterproof Search Coils

Take on everything from trash-filled parks to wide-open relic sites with the Fisher F70 Three-Coil Combo. This versatile package includes three waterproof search coils, allowing you to quickly adapt the detector for target separation, balanced everyday performance, or maximum ground coverage.

The F70 operates at a versatile 13 kHz frequency and combines fast response, numerical target identification, GroundGrab automatic ground balancing, adjustable discrimination, notch control, and two programmable memory settings. Its lightweight, well-balanced design is built for long hunts without unnecessary fatigue.

Three Waterproof Search Coils Included

5" DD Search Coil
Ideal for trashy sites, tight spaces, and areas containing closely spaced targets. Its compact DD detection field delivers excellent separation and maneuverability around playground equipment, foundations, roots, and heavy vegetation.

9¾" Concentric Search Coil
A balanced general-purpose option for coin shooting, jewelry hunting, and everyday detecting. The concentric design provides dependable target identification, accurate pinpointing, and efficient coverage.

11" DD Search Coil
Designed for greater ground coverage and increased depth potential. The larger DD configuration performs well in mineralized soil and is an excellent choice for fields, beaches, and relic-hunting locations.

GroundGrab Ground Balancing

GroundGrab measures the soil’s magnetic properties and automatically adjusts the detector to reduce interference from ground minerals. The F70 can balance across a broad range—from ferrite-rich soil to conductive salt conditions—and also provides manual adjustment for users who want greater control.

Detailed Target Information

The F70 displays probable target conductivity on a 0–99 numerical scale. Visual target categories, target-confidence information, ground-mineralization data, and depth readings provide useful information for evaluating targets before digging.

Customizable Search Modes

Discrimination Mode allows you to reject unwanted targets, adjust notch settings, choose audio responses, and customize the detector for specific hunting conditions.

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

Two programmable memory settings make it easy to save and recall preferred configurations or switch between different types of hunting.

Waterproof-Coil Notice

All three included search coils are waterproof and may be used in wet grass, mud, and shallow water. The F70 control housing is not waterproof and must remain dry.
