Minn Kota Heading Sensor for Bluetooth i-Pilot Spot-Lock Jog

The Minn Kota 1866680 is the small but meaningful sensor that adds proper heading awareness to Bluetooth-enabled i-Pilot trolling motor installations. Without a heading sensor, the i-Pilot's GPS-based Spot-Lock function holds the boat at a saved GPS position - which works fine but doesn't know which direction the boat's bow is actually pointing. With the heading sensor, the i-Pilot can also adjust the Spot-Lock position in deliberate increments based on the boat's heading - the Jog feature - which transforms the way you fish a Spot-Lock.

What the heading sensor actually does. The 1866680 contains a fluxgate compass and Bluetooth radio. The compass measures Earth's magnetic field to determine the boat's heading (the direction the bow is pointing) - same fundamental sensor technology as a marine instrument compass or autopilot heading reference. The Bluetooth radio reports that heading data to the trolling motor's i-Pilot electronics in real time. The trolling motor then knows both the boat's GPS position (from the integrated GPS in the i-Pilot system) AND the boat's heading (from this sensor) - the combined position-plus-heading data enables the Jog feature.

The Spot-Lock Jog feature - what makes the heading sensor meaningful. Standard Spot-Lock holds the boat at a saved GPS position. Press Spot-Lock, the motor takes over and keeps the boat over that exact GPS coordinate regardless of wind / current. But often you want to move the boat slightly - the fish are 10 feet to the left of where you locked, you want to reposition to a slightly different angle on the structure, or you want to systematically work an area in deliberate increments rather than re-locking from one position to another. With Jog and the heading sensor: press the Jog buttons (forward / back / left / right) on the i-Pilot remote, the trolling motor moves the Spot-Lock position 5 feet in that cardinal direction without breaking lock. The boat's heading-relative motion is what makes this work - the sensor tells the motor which way is "forward" relative to the boat's bow, and the motor moves accordingly. Without heading data, Jog can't determine which direction the operator actually wants to move because there's no reference to the boat's orientation.

5-foot Jog increments in any cardinal direction. Each Jog button press moves the Spot-Lock position 5 feet in the corresponding direction relative to the boat's bow. Forward = 5 feet ahead of where the bow is pointing. Backward = 5 feet behind the bow. Left = 5 feet to the boat's port side. Right = 5 feet to starboard. Press multiple times to move further (3 forward presses = 15 feet ahead). Press different directions in sequence for diagonal movement (1 forward + 1 right = 5 feet ahead and 5 feet right). The 5-foot increment is fine enough for precise positioning over structure, coarse enough that you don't have to press 50 times to move a meaningful distance.

Compatible with Bluetooth-enabled i-Pilot systems only. The 1866680 specifically requires the Bluetooth-equipped variant of the i-Pilot system (model year 2017 and after). Older i-Pilot systems use a different wireless protocol (the original i-Pilot wireless that predates Bluetooth integration) and don't communicate with the 1866680. For owners with older i-Pilot systems, the heading sensor isn't compatible - check the trolling motor's documentation or the original i-Pilot remote to confirm Bluetooth support before ordering.

How to determine if your i-Pilot is Bluetooth-enabled. Three indicators. One: model year - i-Pilot systems shipping with model year 2017 and after trolling motors typically include Bluetooth. Two: original remote - the Bluetooth-enabled remote has the Bluetooth logo / capability noted on the back of the remote or in the documentation. Three: trolling motor documentation - the trolling motor's user manual specifies whether the i-Pilot system is Bluetooth-equipped. If you have any doubt, contact Minn Kota with your trolling motor model number for definitive compatibility confirmation before ordering.

Comes standard with select trolling motors. The 1866680 ships pre-installed on certain Minn Kota trolling motors (model year 2017 and after) - if you have any of these motors, you don't need to order this part separately. Standard inclusion list: Ultrex (cable-steer freshwater bow-mount), Ulterra (auto-stow / deploy electric-steer freshwater bow-mount), Terrova (electric-steer freshwater bow-mount), Riptide Ulterra (saltwater equivalent of Ulterra), Riptide Terrova (saltwater equivalent of Terrova). For these motors, the heading sensor is integrated into the motor's electronics from the factory.

Add-on accessory for PowerDrive line. The 1866680 is available as an add-on accessory for PowerDrive and Riptide PowerDrive trolling motors that ship with Bluetooth i-Pilot (model year 2017 and after). PowerDrive motors don't include the heading sensor in the standard configuration - if you have a PowerDrive with Bluetooth i-Pilot and want the Jog feature, you need to add this 1866680 sensor as a separate purchase.

Wireless install - no wiring required. The heading sensor is a self-contained battery-operated wireless module. Mount it in a horizontal flat location on the boat (typical location: the center console, near the helm, or in a dry equipment compartment - any location where the sensor's compass can read magnetic north accurately without nearby ferromagnetic interference). The sensor pairs with the Bluetooth i-Pilot system via the standard pairing procedure. No wiring runs from the sensor to the trolling motor - all communication is wireless via Bluetooth.

Compass calibration. After install, the heading sensor requires a one-time calibration to compensate for the boat's local magnetic environment (every boat has unique magnetic signatures from steel hardware, ferromagnetic accessories, electrical wiring carrying current, etc.). The calibration procedure is straightforward: drive the boat in a slow circle through 360 degrees on calm water while the sensor learns the local magnetic environment. Re-calibration may be needed if you add significant new magnetic equipment to the boat (large new electronics, ferrous accessories) that changes the local magnetic field.

Battery operation. The 1866680 runs on internal batteries (replaceable) for typical multi-season operation. Battery life is meaningful - typically 1-2 years of normal fishing-day use before battery replacement is needed. The sensor's low-power Bluetooth radio operates only when actively reporting heading to the trolling motor (not transmitting continuously), which extends battery life dramatically versus continuous-transmit alternatives.

What's in the box. The 1866680 heading sensor with internal batteries pre-installed, mounting hardware (typical adhesive mounting strip plus optional screw mounting), basic install / pairing instructions. Required separately: a Bluetooth-equipped i-Pilot trolling motor system (the heading sensor doesn't work without one), and any additional mounting hardware specific to your boat's layout.

One-year limited warranty. Standard Minn Kota warranty terms apply. Service runs through the Minn Kota authorized service network.
