To TRACK a school of fi sh, the HD800 console must
be connected to a
GPS
unit with NMEA 0183 output.
The sentence format recognized by the HD800 is RMC
and GLL, VTG. This format includes; time, latitude,
longitude, speed over ground, course over ground and
date. All this information is used to track and log each
track into menu 4.
NOTE:
There are many GPS models on the market rang-
ing in speed and reliability. All GPS units give latitude,
longitude, and calculate heading. Heading is calculated
between two or more GPS updates. Because bearing
is a calculation, the greater the distance between GPS
readings, the more accurate your heading will become.
WESMAR recommends a vessel speed of four knots or
greater, with no course change during the target marking
phase. Once tracking is engaged, the vessel may then
pursue any course.
To TRACK fi sh detected in the sonar mode, place the
cursor over the fi sh with the Cursor Position Switch.
Immediately lift up the
TRACK
SWITCH. When the
TRACK SWITCH is clicked up for the fi rst time, the
HD800 console will calculate the GPS location of the
fi sh, which it holds in memory. When the GPS location
is calculated, the fi shlupe to the right of the screen will
disappear.
Continue to sweep the target. When noticeable move-
ment of the school is detected, mark the target for the
second time with the cursor. Immediately lift up the
TRACK
SWITCH. Tracking is engaged when the fi sh
