LiveScope and Perspective Sonar Setup

From the LiveScope or Perspective sonar view, select Menu > Sonar Setup.
Appearance: Configures the appearance of the sonar screen
page 87).
Layout: Configures the layout of the sonar screen
Noise Reject: Reduces noise and interference and attempts to remove returns that are not actually targets in
the water.
Ghost Reject: Reduces the occurrence of "ghost" images, which are duplicated or reflected images that are not
actually targets in the water. The Ghost Reject setting sends more transmit power forward in the water to
see farther with less noise generated by the bottom. Adjusting the Ghost Reject and Noise Reject settings
together reduces the occurrence of "ghost" images most effectively. This feature is available in LiveScope
Forward orientation only.
TVG: Adjusts the time varying gain, which can reduce noise.
This control is best used for situations when you want to control and suppress clutter or noise near the
water surface. It also allows for the display of targets near the surface that are otherwise hidden or masked
by surface noise.
Overlay Data: Sets the data shown on the sonar screen.
Installation: Configures the transducer
page 81).

LiveScope and Perspective Appearance Settings

From the LiveScope or Perspective sonar view, select Menu > 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 Menu > 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.
