1. From a sonar view, select > Frequency.
2. Select Add.
3. Enter a frequency.

Sonar Gain

The gain setting controls the sensitivity of the sonar receiver to compensate for water depth and water clarity. Increasing the gain shows more detail, and decreasing the gain reduces screen clutter.

Setting the Gain Automatically

1. Select > Gain.
2. Select Enable Auto Gain if applicable.
3. Select an option:
   • To display higher-sensitivity, weaker sonar returns with more noise automatically, select Auto High.
   • To display medium-sensitivity sonar returns with moderate noise automatically, select Auto Med.
   • To display lower-sensitivity sonar returns with less noise automatically, select Auto Low.

Setting the Gain Manually

1. From a sonar screen, select  > Gain.
2. Select or until you begin to see noise in the water portion of the screen.
3. Select to decrease the gain.

Adjusting the Range of the Depth Scale

You can adjust the range of the depth scale that appears on the right side of the screen. Automatic ranging keeps the bottom within the lower third of the sonar screen and can be useful for tracking the bottom where there are slow or moderate terrain changes.

When the depth changes dramatically, like a drop off or cliff, manually adjusting the range allows a view of a specified depth range. The bottom is shown on the screen as long as it is anywhere within the manual range established.

1. From a sonar screen, select  > Range.
2. Select an option:
   • To allow the device to adjust the range automatically based on the depth, select Auto.
   • To increase or decrease the range manually, select or

1. From a sonar screen, select  > Sonar Setup > Depth Line.
2. Select.
3. To adjust the Depth Line, select.

Setting the Scroll Speed

You can set the rate at which the sonar image moves across the screen. A higher scroll speed shows more detail, especially while moving or trolling. A lower scroll speed displays sonar information on the screen longer. Setting the scroll speed on one sonar view applies to all the sonar views.

1. From a sonar view, select > Sonar Setup > Scroll Speed.
2. Select an option:
3. To adjust the scroll speed automatically using speed-over-ground, select Auto. The Auto setting selects a scroll rate to match the boat speed, so targets in the water are drawn with the correct aspect ratio and appear less distorted. When viewing Garmin ClearVü or SideVü sonar views, it is recommended to use the Auto setting.

• To use a very fast scroll speed, select Ultrascroll^®. The Ultrascroll option quickly scrolls new sonar data, but with a reduced image quality. For most situations, the Fast option provides a good balance between a quickly scrolling image and targets that are less distorted.

Setting the Bottom Search Limit

You can set a maximum depth at which the auto range feature searches for the bottom. A lower limit acquires data about the bottom faster than a higher limit.

1. From a sonar screen, select  > Sonar Setup > Bottom Search Limit.
2. Select a range.

Sonar Appearance Settings

From a sonar view, select  > Sonar Setup > Appearance.

• Color Scheme: Sets the color scheme.

• Fish Symbols: Sets how the sonar interprets suspended targets.

Turning on the A-Scope

The a-scope is a vertical flasher along the right side of the full-screen sonar view. This feature expands the most recently received sonar data so that it is easier to see. It can also help detect fish that are close to the bottom. From the full-screen page, select > Sonar Setup > Appearance > A-Scope.

1	A-Scope
2	Diameter of the sonar cone at the present depth

Configuring the Appearance of Suspended Targets

1. From a sonar screen, select  > Sonar Setup > Appearance > Fish Symbols.
2. Select an option.

Sonar Noise Rejection Settings

From a sonar view, select > Sonar Setup > Noise Reject.

Interference: Adjusts the sensitivity to reduce the effects of interference from nearby sources of noise.

When you adjust the interference setting from off through low, medium, and high, noise is gradually removed, but there is little effect on the strong target returns. You should use the lowest interference setting that achieves the desired improvement to remove interference from the screen. Correcting installation issues that cause noise is the best way to eliminate interference.

Surface Noise: Hides sonar returns near the surface of the water. Hiding surface noise helps reduce screen clutter.

Surface noise is caused by interference between the transducer and water. You can hide surface noise to help reduce clutter. Wider beam widths (lower frequencies) can show more targets, but can generate more surface noise.

TVG: Reduces surface 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 Number Settings

You can customize the data shown on the sonar screen.

From a sonar screen, select > Overlay Numbers.
