Fisher M-97 Metal Detector

Fisher M-97 Industrial Metal Detector

Industrial-Grade Detection with Adjustable Sensitivity

The Fisher M-97 is a professional-grade industrial metal detector engineered to locate valve boxes, manhole covers, survey markers, and other metallic objects buried in soil, asphalt, or concrete. With selectable 8-inch or 11-inch waterproof coils, it offers the depth and precision required for utility, construction, and maintenance crews working in challenging environments.

Simplified Controls with Full Adjustability

The M-97 is designed around an intuitive three-control system: two rotary knobs and a push button. Operators can adjust sensitivity, tune quickly with push-button reset, and use ground-effect rejection to eliminate interference from mineralized soil, wet pavement, or surface clutter. A double-locking adjustable shaft provides stability and collapses for compact storage.

Detection Feedback and Accuracy

The M-97 provides both audio and visual feedback to improve locating accuracy. The analog meter indicates signal strength and polarity, while the audio tone rises in frequency as the detector nears a target. An ultra-slow auto-tune function reduces drift, maintaining stability and consistent performance during extended use.

• Audio response scales with target strength
  
  
• Analog meter supports confirmation and pinpointing
  
  
• Manual ground balance allows precise adjustment in varying soil conditions

Coil Options and Field Performance

Operators can choose between an 8-inch or 11-inch waterproof search coil, depending on the depth and coverage required. Both coils are pressure-sealed for reliable operation in wet environments and can withstand exposure to mud, snow, or standing water. The stem and coil assembly fold flat, making transport and storage efficient.
