Easily find buried metals through concrete or asphalt with the Fisher M-66 Valve and Box Locator with 8” Search Coil. This locator is ideal for finding manholes (up to 42” deep), valve boxes (up to 18” deep), water or gas meters, conduit, survey markers, and all metals including aluminum, copper, iron, brass, lead, nickel, and tin. With a combination of accuracy, sensitivity, and excellent ground penetration, the M-66 Locator is ideal for finding any hidden metallic object.
Easy Operation for Any Skill Level The M-66 Locator features an ergonomic handle and an easy-to-access control panel with two knobs, a button, and an analog meter. One knob is for adjusting the instrument’s sensitivity to suit the method used in searching. The other knob is for turning the M-66 on and off and also to electronically balance the M-66 to compensate for the ground surface’s natural mineral content. There is also a button that when pressed will show the battery’s strength on the analog meter. The length of the detector’s pole can also be adjusted to suit the user’s height.
Audio and Visual Alerts During a search, the detector provides visual and audio signals to alert you of the sensors’ reactions to targets. The reading on the meter increases and the audible tone gets louder as the detector approaches a target.
Eliminates False Signals Being a Ground Effect Rejection VLF – or Very Low Frequency – metal detector, the M-66 Locator automatically eliminates false signals commonly caused by wet ground foliage and pavement and ground mineralization. This way, the detector will only sense metal targets that you’re looking for, preventing the waste of time, money, and effort.
Accurate, highly sensitive, and easy to use, the M-66 Valve and Box Locator with 8” Search Coil is a great option for finding hidden metallic objects through the soil, concrete, or asphalt.
