The Fisher M-66 Metal Detector is a specialized device designed for locating buried or paved-over valves, boxes, vaults, survey markers, water or gas meters, conduit, manholes, and other concealed metallic objects. This all-metal detector is capable of detecting a wide range of metals, including aluminum, brass, copper, iron, nickel, steel, and tin.
Featuring a combination of sensitivity, accuracy, and maximum ground penetration, the M-66 eliminates guesswork when it comes to pinpointing hidden metallic objects. It provides both audio and visual indications to assist in the detection process. The electronic balance of the M-66 can be quickly and easily tuned within seconds, ensuring optimal detection performance.
Built to uphold the Fisher tradition of affordability, durability, and user-friendliness, the M-66 is designed to deliver reliable performance in the field. It comes with a two-year limited warranty, providing peace of mind to users.
With an operating frequency of 4.5 kHz, the M-66 offers efficient detection capabilities. The sensitivity is rated at 0.2mV RMS for full scale, allowing for precise detection of metallic objects. The output indication options include a meter with a linear scale of 0-100 and 1 milliamp output. The built-in speaker has an impedance of 16 ohms and operates at an audio frequency of 450 kHz.
The M-66 Metal Detector is powered by two 9V batteries, providing ample operating time in the field. Additionally, the search coil is immersible in water, enabling underwater detection if necessary.
