Garmin GPSMAP 751xs - Manual (Page 32)

Adjusting the Distance from Shore
CAUTION
The Auto Guidance feature is based on electronic chart
information. That data does not ensure obstacle and bottom
clearance. Carefully compare the course to all visual sightings,
and avoid any land, shallow water, or other obstacles that may
be in your path.
NOTE: Auto Guidance is available with premium charts, in
some areas.
The Shoreline Distance setting indicates how close to the shore
you want the Auto Guidance line to be placed. The Auto
Guidance line may move if you change this setting while
navigating. The available values for the Shoreline Distance
setting are relative, not absolute. To ensure the Auto Guidance
line is placed the appropriate distance from shore, you can
assess the placement of the Auto Guidance line using one or
more familiar destinations that require navigation through a
narrow waterway.
1 Dock your vessel or drop the anchor.
2 Select Settings > Navigation > Auto Guidance >
Shoreline Distance > Normal.
3 Select a destination that you have navigated to previously.
4 Select Navigate To > Guide To.
5 Review the placement of the Auto Guidance line, and
determine whether the line safely avoids known obstacles
and the turns enable efficient travel.
6 Select an option:
• If the placement of the Auto Guidance line is satisfactory,
select Menu > Stop Navigation, and proceed to step 10.
• If the Auto Guidance line is too close to known obstacles,
select Settings > Navigation > Auto Guidance >
Shoreline Distance > Far.
• If the turns in the Auto Guidance line are too wide, select
Settings > Navigation > Auto Guidance > Shoreline
Distance > Near.
7 If you selected Near or Far in step 6, review the placement
of the Auto Guidance line, and determine whether the line
safely avoids known obstacles and the turns enable efficient
travel.
Auto Guidance maintains a wide clearance from obstacles in
open water, even if you set the Shoreline Distance setting to
Near or Nearest. As a result, the chartplotter may not
reposition the Auto Guidance line, unless the destination
selected requires navigation through a narrow waterway.
8 Select an option:
• If the placement of the Auto Guidance line is satisfactory,
select Menu > Stop Navigation, and proceed to step 10.
• If the Auto Guidance line is too close to known obstacles,
select Settings > Navigation > Auto Guidance >
Shoreline Distance > Farthest.
• If the turns in the Auto Guidance line are too wide, select
Settings > Navigation > Auto Guidance > Shoreline
Distance > Nearest.
9 If you selected Nearest or Farthest in step 8, review the
placement of the Auto Guidance line, and determine whether
the line safely avoids known obstacles and the turns enable
efficient travel.
Auto Guidance maintains a wide clearance from obstacles in
open water, even if you set the Shoreline Distance setting to
Near or Nearest. As a result, the chartplotter may not
reposition the Auto Guidance line, unless the destination
selected requires navigation through a narrow waterway.
10 Repeat steps 3 through 9 at least once more, using a
different destination each time, until you are familiar with the
functionality of the Shoreline Distance setting.
