A direction finding system comprising: at least one first hand holdable
unit comprising circuitry that transmits a radio beacon signal; and at
least one second hand holdable unit having a display screen and
comprising direction finding (DF) circuitry that receives a radio beacon
(RB) signal transmitted by a first unit of the at least one first unit
and determines from the received radio beacon signal an azimuth angle for
the location of the first unit; wherein the controller generates a
display on the display screen responsive to the azimuth angle that
indicates a location of the first unit.
