LiveScope and Perspective Appearance Settings

From the LiveScope or Perspective sonar view, select Options > Sonar Setup > Appearance.
Color Scheme: Sets the color palette.
Color Gain: Adjusts the contrast of colors shown on the screen.
You can select a higher color gain value to see minor variances in targets with large color changes. You can
select a lower color gain value to see more similar colors in the same situation.
Trails: Sets the how long the trails appear on the screen. The trails show the movement of the target.
Bottom Fill: Colors the bottom brown to distinguish it from the water returns. Not available in Perspective mode.

LiveScope and Perspective Layout Settings

From the LiveScope or Perspective sonar view, select Options > Sonar Setup > Layout.
Grid Overlay: Shows a grid of range lines. The Grid option shows a square grid. The Radial option shows a
circular grid with radial angle lines.
Scroll History: Shows the sonar history on the side of the screen. Not available in Perspective mode.
Beam Icon: Selects the icon used to show the direction of the transducer beam.
Beam Overlay: Enables an outline to show where the transducers are oriented in relation to each other, when
two or more calibrated Panoptix transducers are connected.
On-screen Control: Shows the on-screen buttons.
Reverse Range: Adjusts the amount of range shown behind the transducer.
Compress Range: In forward views, compresses the forward range farther away from the boat and expands the
range closer to the boat. This allows you to see closer objects more clearly while keeping farther objects on
the screen.

LiveScope and Perspective Transducer Installation Settings

From the LiveScope or Perspective sonar view, select Options > 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.
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.
Calibrate Compass: Calibrates the internal compass in the Panoptix transducer
page 91).
This applies to LiveScope transducers with an internal compass.
Orientation: Controls if the transducer is in down or forward installation mode. The Auto setting uses the AHRS
sensor to determine the orientation.
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.
Restore Sonar Defaults: Restores the sonar settings to the factory default values.
