This Bluetooth-enabled sensor optimises Spot-Lock on i-Pilot or i-Pilot Link by enabling the Jog feature, which lets you move your Spot-Lock five feet in any direction at the push of a button. It also minimises boat swing for a better hold. Available as an add-on for i-Pilot and i-Pilot Link systems on PowerDrive and Riptide PowerDrive, and comes standard on all other models.
