Perspective Appearance Settings; Panoptix Transducer Installation Settings - Garmin GPSMAP 7400 Series Owner's Manual

Perspective Appearance Settings

the Perspective sonar view, select Menu > Sonar Setup > Appearance.
Color Scheme: Sets the color palette.
Color Gain: Adjusts the intensity of colors shown on the screen.
You can select a higher color gain value to see targets higher in the water column. A higher color gain value
also allow you to differentiate low intensity returns higher in the water column, but this causes a loss in the
differentiation of the returns at the bottom. You can select a lower color gain value when targets are near the
bottom, to help you distinguish between targets and high intensity returns such as sand, rock, and mud.
Trails: Sets the how long the trails appear on the screen. The trails show the movement of the target.
Grid Overlay: Shows or hides grids of range lines. The Grid option shows a square grid. The Radial option shows
a circular grid with radial angle lines.
Boat Icon: Shows the icon of the boat in the upper-right corner.

Panoptix Transducer Installation Settings

From a Panoptix sonar view, select Menu > Sonar Setup > Installation.
Install Depth: Sets the depth below the water line where the Panoptix transducer is mounted. Entering the actual
depth at which the transducer is mounted results in a more accurate visual presentation of what is in the
water.
Bow Offset: Sets the distance between the bow and the forward view Panoptix transducer installation location.
This allows you to view the forward distance from the bow instead of the transducer location.
This applies to Panoptix transducers in the Garmin FrontVü, LiveVü Forward, and RealVü 3D Forward sonar
views.
Beam Width: Sets the width of the down view Panoptix transducer beam. Narrow beam widths allow you to see
deeper and farther. Wider beam widths allow you to see more coverage area.
This applies to Panoptix transducers in the Garmin FrontVü, LiveVü Down, and LiveVü Forward sonar views.
Use AHRS: Enables the internal attitude heading and reference system (AHRS) sensors to detect the installation
angle of the Panoptix transducer automatically. When this setting is turned off, you can enter the specific
installation angle for the transducer using the Pitch Angle setting. Many forward view transducers are
installed at a 45-degree angle and down view transducers are installed at a zero-degree angle.
Flipped: Sets the orientation of the Panoptix sonar view when the down view transducer is installed with the
cables pointing toward the port side of the boat.
This applies to Panoptix transducers in the LiveVü Down, RealVü 3D Down, and RealVü 3D Historical sonar
views.
Calibrate Compass: Calibrates the internal compass in the Panoptix transducer
page 84).
This applies to Panoptix transducers with an internal compass, such as the PS21-TR transducer.
Orientation: Controls if the transducer is in down or forward installation mode. The Auto setting uses the AHRS
sensor to determine the orientation.
This applies to PS22 and LiveScope transducers.
Focus: Adjusts the sonar view to compensate for the speed of sound in water. The Auto setting uses the
temperature of the water to calculate the speed of sound.
This applies to LiveScope transducers.
Restore Sonar Defaults: Restores the sonar settings to the factory default values.
