Radar Front-of-boat Offset The front-of-boat offset compensates for the physical location of the radar scanner on a boat, if the radar scanner does not align with the bow-stern axis. Measuring the Potential Front-of-boat Offset 1. Using a magnetic compass, take an optical bearing of a stationary target located within viewable range. 2. Measure the target bearing on the radar. 3. If the bearing deviation is more than +/- 1°, set the front-of-boat offset. Setting the Front-of-boat Offset Before you can set the front-of-boat offset, you must measure the potential front-of-boat offset (see previous procedure). The front-of-boat offset setting configured for use in one radar mode is applied to every other radar mode and to the Radar Overlay. 1. From the Home screen, select Radar > Radar Setup > Front of Boat. 2. Select and hold Up or Down to adjust the offset.
