Change the Max Depth
The Max Depth was set when you first configured the unit with the Quick Setup dialog box (see Getting Started: Quick Setup). Use
the instructions in this section to adjust the maximum depth setting.
1. Main Menu (Advanced User Mode): Press the MENU key twice. Select the Sonar tab.
2. Select Max Depth.
3. Select one of the following:
Auto: the control head will acquire bottom readings as needed (within the capabilities of the unit).
Set to match the body of water depth: the control head will not attempt to acquire sonar data below that depth, so more detail
will be shown on the display.
NOTE: Side Imaging units default to the Side Imaging range setting if the SI Range is set deeper than the Max Depth. See Side
Imaging Overview for more information.
Select the Digital Depth Source (HELIX DI GPS only)
Depending on the depth, the HELIX DI GPS control head will automatically choose the 2D conical beams or the Down Imaging
beams to display the depth digital readout. If the depth is deeper than 350 ft, set the Digital Depth Source to 2D Element.
1. Main Menu (Advanced User Mode): Press the MENU key twice. Select the Sonar tab.
2. Select Digital Depth Source.
3. Select Auto or 2D Element.
Auto: The control head will acquire the digital depth as needed.
2D Element: Select 2D Element if the depth is deeper than 350 feet. Down Imaging is not available with this setting.
Change the Water Type
The Water Type was set when you first configured the unit with the Quick Setup dialog box (see Getting Started: Quick Setup). Water
Type affects the accuracy of deep water depth readings and configures the control head for operation in fresh or salt water. Use the

1. Main Menu (Advanced User Mode): Press the MENU key twice. Select the Sonar tab.
2. Select Water Type.
3. Select one of the folowing for your water type and depth conditions:
