Sonar settings

Sonar settings can be accessed by clicking the gear icon in the top right corner.


This will open a menu with all available settings for your model of Deeper sonar. You can close the menu at any time by sliding it to the right.

Fishing mode lets you choose between different fishing modes: Onshore, Boat, Ice fishing, Bait Boat, Show Scan Only, Scan Only (without GPS). This setting is not available for Deeper START.

Sonar display – switch between Raw and Basic sonar display. Raw sonar display shows detailed sonar, without any filtering. Basic sonar display filters out the amount of information and shows only the basic data – bottom structure, depth, fishes. 

Beam angle – switch between the sonar beam angles of your Deeper sonar. This setting is not available for Deeper START


Sensitivity – controls how much detail is shown on the display and can be used to adjust the sensitivity of all sonar frequencies. If you use a high sensitivity, the sonar display will show everything, including small baitfish and floating debris in the water. When operating in very clear water or at greater depths, you should increase the sensitivity, so you can see even weaker returns that may be of interest. Decreasing the sensitivity eliminates clutter from the display, which can occur when the water is muddy. If the sensitivity is set too low, the display will not show a lot of sonar returns that could be fish. We recommend starting from 100% sensitivity and then gradually decreasing sensitivity until you get the best results. 

Show fish icons – turn on/off special algorithms that interpret fishes and mark them with fish symbols on the screen.

Fish size – When Fish Icons are enabled, allows you to choose which fish size to show (Large/Medium/Small). You can choose which size to show by adjusting the slider. Selecting L/M/S will result in all 3 sizes being shown, L/M will show only large and medium sized fishes, while L setting will show only large fishes. This feature will only work if Fish icons are enabled.

Show depth – enables or disables depth readings that are displayed above or below fish icons. You can choose the distance from surface to the fish (Fish icon with arrow up) or distance from the bottom to the fish (Fish icon with arrow down). This feature will only work if Fish icons are enabled.

Fish alarm – enable fish alarms, that will make a sound alarm whenever a fish is detected. This feature will only work if Fish icons are enabled.

Color palette – allows you to choose the most convenient color palette for viewing your sonar data based on the environment, conditions and the time of day you are fishing. Alongside the Classic color palette, there are two other options – Day and Night - which can be used for the best viewing of your sonar readings in either bright sunny conditions (Day mode) or low light conditions (Night mode). 


The Night Fishing feature should be turned on when fishing at night or in low light conditions. With the Deeper START it can be activated immediately, whereas with the Deeper PRO, PRO+ and CHIRP models you will need to replace the standard cover with a Deeper Night Fishing Cover first. Night Fishing mode activates a blinking light that is only visible through a transparent cover.

Additional settings:

Shallow mode – available for CHIRP models only. Automatically switches the scanning beam to Narrow (7°) when scanning shallow waters with depths below 2m / 4 ft.

Low power mode  available for CHIRP models only. Enabling this will make your sonar consume less battery, but result in slightly reduced scanning resolution and quality.
