Lowrance Point-1 GPS/GLONASS Antenna
The Lowrance Point-1 is the ideal position and heading device. The Point-1 provides extremely accurate and rapid boat position and speed updates. In addition – unlike other position-only antennas – the Point-1 provides heading for accurate boat direction at any speed and for radar/chart overlay.
The Point-1 easily connects to any HDS Gen2, HDS Gen2 Touch or Elite-7 display or any NMEA 2000 network. It is fully waterproof and can be pole or surface mounted on any boat.
- NMEA 2000 position and heading sensor
- Supports GPS and GLONASS, Galileo-capable with future software update
- Supports SBAS including WAAS/EGNOS/MSAS
- 10 Hz updates for smooth and accurate location
- Integrated electronic compass provides 10Hz heading for chart stabilization and radar overlay, plus accurate course over ground even at low speeds
- Compact, rugged design for all marine environments and fully waterproof
- Includes spat/pole mount
- Not recommended for use with MARPA or Autopilot
NOTE: If you had an LGC-2000, you'll need to add the 127-05 cable to connect it:

What is the difference between the Point-1 and LGC-4000 antenna?
The Point-1 antenna updates the old LGC model by adding additional satellite channels (up to 20) and GLONASS support, as well as an integrated heading sensor.
Will Point-1 work with my HDS Gen1?
The Point-1 antenna/heading sensor is a standard NMEA2000 device. Therefore, it will connect to any NMEA2000 backbone and communicate with any NMEA device on that same network. The HDS Gen2 models, both keypad and touch, with software version 2.0 or higher will have GPS damping and filtering features, as well as the ability to initiate heading calibration from the HDS, that will not be present in any HDS Gen1.
I had an LGC-2000. How do I use a Point-1 to replace it?
The Point-1 antenna cannot be connected directly to a chartplotter. If you had an LCX, LMS or GlobalMap model that used the LGC-2000, you can still connect it to the Point-1, but you will need an accessory adaptor cable AND the original NMEA 2000 cables and T-connectors that came with your unit. Please see the diagram above that illustrates this.
How do I select the Point-1 for GPS data on my HDS?
GPS data selection is the same as any NMEA external antenna. GPS sources can be found in the HDS "Data Sources" menu. This can be found on keypad units, by pressing Menu—Menu—Network – Data Sources. Then selecting GPS, then All Data. You should see the Point-1 listed in this menu. On Touch units, press the Pages key, tapping Settings, tapping Network, tapping Data Sources. Then selecting, GPS, then All Data. You should see the Point-1 in this menu. HDS also has an Auto Select feature, when this is enabled the HDS will choose the antenna with the best Signal to Noise Ratio (SNR) from the available satellites. Depending on mounting location, view of the sky, etc. having Auto Select enabled may not always choose the Point-1 for GPS data.
How do I select the Point-1 for heading data on my HDS?
Selecting the Point-1 for heading is the same process as selecting the Point1 for GPS. However, since heading is determined by a compass, rather than from the satellites, heading can be found under Vessel, from the Data Source Selection page, rather than GPS.
Where should I mount my Point-1?
Point-1 antennas contain a very sensitive electronic compass in the housing. Therefore it is very important to mount the antenna away from anything that emits a magnetic field e.g. Trolling motors, VHF antennas, and radars. Just like any other GPS antenna, Point 1 should be mounted where it has a clear, unobstructed view of the sky in order to ensure quality signals from the satellites.
