Plot (Track Plot) View
If your separate Loran C, Decca or GPS receiver has the
proper NMEA #0183 output capability, or if you own the
Interphase Star Pilot GPS
,
Pilot GPS
or
Interphase
Pilot Loran
, you can easily interface the unit to the
Twinscope
to show both digital and graphic navigation
information. Possible information obtained from a
navigation receiver can include track plotting and digital
Lat/Lon readings. The
Twinscope
can also mark
positions with several different graphic symbols. These
functions will not work unless you are able to
successfully interface a navigational instrument such as a
Loran C, Decca or GPS receiver to the
Twinscope
. (see
page 66)

The Track Plot square on the display shows the current
plotter range (1/4, 1/2, 1, 2, 4, 8, 16, 32, 64, 128) in
statute (U.S.) or nautical miles, depending on the units of
measure selected.

Pressing the "

" soft key allows you to mark your
current position on the track plot screen with one of three
graphic icons - an anchor, a fish or a flag. Each icon can
be used up to ten times on a track plot for a total of 30
possible marks. When power is removed from the
Twinscope
, the marks are erased.
