Lowrance Point-1 GPS/Heading Antenna Module 000-11047-002

The Lowrance Point-1 is an essential upgrade for any serious angler using a NMEA 2000-compatible Lowrance system. It is not just a GPS antenna; it is a dual-purpose device that significantly improves both your navigation accuracy and your ability to target structure effectively.

Key Capabilities

• True Heading Sensor: Unlike standard GPS antennas that only know your “Course Over Ground” (where you are moving), the Point-1 has an integrated electronic compass. This tells your fish finder exactly which direction the bow of the boat is pointing, even when you are sitting perfectly still in the wind or current.

• Navigation Accuracy: It provides a 10Hz update rate (10 times per second), ensuring your boat position on the chart is smooth, rapid, and highly accurate.

• Chart Stabilization: Because it knows your heading, it prevents your map from “spinning” when you are moving slowly or stopped. It is essential for overlaying radar or using mapping features effectively.

Compatibility with Your Build

• HDS PRO Integration: Yes, the Point-1 is fully compatible with the Lowrance HDS PRO series. It connects via a standard NMEA 2000 network.

• Networking: It is an NMEA 2000 device. You must have a powered NMEA 2000 backbone on your boat to connect this antenna. If you don’t already have one, you will need a NMEA 2000 Starter Kit (which includes power T-connectors, backbone cables, and terminators).

Important Usage Notes

• Not for Autopilot: While it is an excellent heading sensor for your fish finder, Lowrance does not recommend using the Point-1 as the primary heading source for Autopilot systems or MARPA (radar target tracking). Those systems require dedicated, higher-precision heading sensors.

• Calibration: For the heading sensor to work correctly, you must calibrate it once installed. This is a simple process done through your HDS PRO display settings, involving a slow 360-degree turn of the boat.

• Placement: To get the best heading data, mount it on a flat surface as close to the center of your boat as possible, away from large metal objects, speakers, or other sources of magnetic interference.

Summary Checklist for Installation

• [ ] NMEA 2000 Network: Ensure your boat has a powered NMEA 2000 backbone.

• [ ] Calibration: Once connected, remember to perform the compass calibration via your HDS PRO menu.

• [ ] Mounting: Use the included pole/spat mount, ensuring it is away from magnetic interference.
