Extremely high frequency signals are
transmitted and received in line with
the front edge of the instrument. This
return signal is processed on board
and is reported to the flashing, then
becoming steady, Red LEDs.
When both Red LEDs "LOCK" onto a
target at the same time, a RED Laser
Pointer automatically spots the target
on the surface, IN A DIRECT LINE to
the target at the angle at which you
have detected the target (object).
NOTE: If one Red LED locks onto a
target and the other does not, but you
feel the target should be there, try
twisting your wrist around the axis of
the LED which is locked onto the
target/object. This is done in an
effort to "Line up" the front edge of
the unit (thus the other LED) with the
target... when the second Red LED
locks on, you have then locked onto
a target or object and direction.
