Turn the instrument on and only the penetration control need be adjusted for most operations, allowing maximum penetration depth for metals. A preset circuit eliminates ground effects caused by highly mineralized materials and false signals due to loop movement.

The M-101 also can effectively locate small metal items carried on or within a person and is substantially more sensitive than the average low cost metal detectors used at airports, so that a given metal item can be found at a greater distance from the search loop itself. Searches in water may be up to the control box. The search loop and cord are waterproof. Backed by Fishers industrial 2 year warranty.
