The M-55
is a turn-on-and-go metal detector for finding buried valves, meter boxes,
paved-over manhole covers and metallic evidence. No tuning or ground rejection
adjustments are needed. just one knob turns the unit on and sets the trash-rejection
(discrimination) level.
The M-55 ignores small metal objects like pull tabs and other
trash, but still locates small pieces of conductive metals, from cartridge
cases to valve box lids.
