Upper Limit

The Upper Limit is the shallowest point in the water column which will be displayed on

the chart.

Lower Limit

The Lower Limit is the deepest point in the water column which will be displayed on the

chart.

Changing the upper and lower limits give you far greater control over the depth range.

This feature lets you "zoom in" the display in almost unlimited combinations.

Depth Cursor

The depth cursor, found by swiping down to the first menu page, consists of a horizontal line with a digital depth box on the right side.

The numbers inside the box show the depth of the cursor. You can move the cursor to any location on the screen, letting you pinpoint

the depth of a target or keep a reference point for a specific depth.

Setup Menu

Units of Measure

 Menu Settings: ft/°C, ft/°F, m/°C or m/°F

This setting allows you to configure the units of measure for your needs.

Chart Speed

 Settings: 10% to 100%

This setting changes the speed at which the display scrolls across the screen. Faster chart speeds will show longer straighter lines as

fish and bottom. Slower chart speeds will show shorter, more curved lines.

Fish Symbols & Depth

Menu Settings

 On/On: Symbols and Depth are Displayed

 On/Off: Fish Symbols Only are Displayed

 Off/Off: No Fish Symbol Display

This feature identifies targets that meet certain standards for possibly being a fish. SonarPhone analyzes all echoes and eliminates

surface clutter, thermoclines, and other undesirable signals. In most instances, remaining targets are fish. This feature displays fish

symbols on the screen in place of the actual fish echoes. There are three fish symbol sizes used to designate the relative size between

targets.

T-BOX ONLY: Fish symbols in the 40 degree cone will appear gray. Fish symbols in both the 40 and 20 degree cones will be black.

IMPORTANT: SonarPhone is sophisticated, but it can be fooled. It may not always be able to distinguish between fish and other larger

suspended objects in the water.

Fish Alarm

The Fish Alarm can be configured to sound for different sizes of fish. Select the setting that is best for you.
