Holding Your Position
Before you can use autopilot features, you must calibrate the trolling motor (Calibrating the Trolling Motor Compass).
You can use Anchor Mode to hold the position of the boat.
The default Anchor Mode setting is Bow Lock, where the motor uses your GPS location and the defined vessel length setting to hold the position of the bow of your boat, allowing the stern to drift (Configuring Bow Lock).1
.
The 
icon appears on the remote control screen. The motor uses
your GPS location and the defined vessel length setting to hold the position of the
bow of your boat.
While Anchor Mode is turned on, you can adjust your anchored position using the arrow keys on the remote control, or using gesture controls (Using Gesture Controls to Adjust Your Held Position ).
To turn off Anchor Mode, press again.
