INTRODUCTION

The M-101 is a metal detector with a small search coil that provides
a concentrated search signal. The M-101 will respond to all types

of metal (rebar, wire mesh, metal conduit, metallic trash, metal­lic targets on the opposite side of surface to be scanned, etc.)
which may be associated with the area that is to be searched.

The M-101 will not respond to non-metallic targets such as plastic
or berglass. The M-101 is not designed to be a wire or pipe tracer.
Fisher Research manufactures other specic equipment for that

purpose.
