long distance wire/cable runs

probe allows a single user to identify up to three wires or
cables at a time for correct labeling with only one trip to
the other end location - cuts down on multiple trips back
and forth

through the wires or cables under test to the bi-color
remote probe; This enables the technician to identify each
of the wires under test at the other end of the cable run and
eliminates the possibility of false high impedance readings
