Lowrance 000-11047-002 Point-1 GPS Antenna with Built-in Compass
Quick take
The Lowrance Point-1 is a marine GPS/GLONASS antenna that also includes an electronic compass, delivering both position and heading for compatible Lowrance displays and NMEA 2000 networks. It’s a practical upgrade if your setup needs more stable direction information for charting, radar/chart overlay, or autopilot integrations. The main limitation is fit, it’s built around Lowrance/NMEA 2000 connectivity and it is not intended for radar MARPA functionality.
Pros and cons
Pros
- GPS position plus built-in heading, useful at speed and for stabilized chart/radar overlay behavior
- NMEA 2000 connection to compatible Lowrance MFDs, including HDS LIVE, HDS Gen2, HDS Gen2 Touch, and Elite-7
- Supports multiple satellite systems and high update-rate operation (10 Hz updates)
- Designed for marine use, fully waterproof with pole or surface mounting
Cons
- Not a standalone solution, you need an NMEA 2000 network and compatible display(s)
- Not recommended if you specifically rely on MARPA radar functionality
- Higher-end, this is typically a system antenna rather than an inexpensive GPS add-on
What buyers think
Buyer-review evidence highlights a consistent theme: the Point-1 improves navigation behavior in real use with Lowrance systems. Several comments focus on more accurate waypoint/charting performance and steadier direction indication, including less “spinning” of direction graphics when anchored or not moving much. Overall, review sentiment centers on accuracy, stability, and straightforward integration with compatible Lowrance equipment, though review detail is limited to a small set of themes rather than a broad technical validation.
Why the Point-1 stands out
Many GPS antennas provide location data, but boat navigation also depends on heading, especially when you care about where the boat is pointing for overlays, course display, and systems that consume heading. The Point-1 is built specifically to handle both:
- Position and speed updates designed for rapid, accurate boat position and speed information.
- Integrated electronic compass heading intended to provide accurate boat direction at any speed, which can help keep overlays and course-related behavior steadier.
- High update rate for smooth location and heading updates (10 Hz updates are part of the feature set).
If your current antenna setup gives good position but inconsistent or “jittery” direction behavior, a combined GPS plus heading sensor like this is often the type of upgrade people are looking for.
Compatibility and connectivity you need to plan for
This antenna is designed to connect through NMEA 2000 to compatible Lowrance displays. It is listed as connecting to:
- HDS LIVE
- HDS Gen2 and HDS Gen2 Touch
- Elite-7 displays
- Any NMEA 2000 network
Practically, that means you should confirm two things before buying: (1) you have NMEA 2000 in your boat or plan to add it, and (2) your chosen Lowrance display models support receiving the antenna’s data over the network.
Key features that matter on the water
Satellite support and update rate
The Point-1 supports GPS and GLONASS and is described as Galileo-capable with a future software update. It also supports SBAS including WAAS, EGNOS, and MSAS, which can help improve accuracy in coverage areas. The 10 Hz update rate is positioned for smooth, responsive location and heading data.
Heading where it counts
The built-in compass is intended to provide heading for chart stabilization and radar/chart overlay, with accurate course over ground even at low speeds. If your use case includes slow-speed maneuvering, anchoring, or you prefer consistent course-direction cues, this is the part of the spec that matters.
Marine mounting and durability
It’s designed with a compact, rugged form factor and is fully waterproof, with support for pole or surface mounting. The kit includes an antenna, a 4-foot cable, NMEA 2000 T-connector, mounting hardware, a gasket seal, and an install guide.
Pros and cons (buyer-fit)
Best for
- Boaters using compatible Lowrance HDS LIVE, HDS Gen2, HDS Gen2 Touch, or Elite-7 systems
- Anyone who wants both position and heading from one dedicated sensor for steadier chart and overlay behavior
- Users who care about navigation stability at low speeds, such as anchoring, trolling, docking, or slow-speed course keeping
Who should avoid it
- Shoppers who need a simple, standalone GPS antenna without NMEA 2000 network support
- Those specifically depending on MARPA radar functionality, since it is not recommended for that use
- Budget-first buyers looking for the cheapest way to add a GPS feed
Verdict
The Lowrance Point-1 is a purpose-built marine GPS plus heading antenna for NMEA 2000 boats running compatible Lowrance displays. If your main pain point is inconsistent direction indication or less stable navigation behavior, the built-in electronic compass and high update-rate design directly target that problem. Just make sure you are ready for the NMEA 2000 integration requirement, and confirm you do not need it for MARPA-related radar functionality.
FAQs
Can I use the Point-1 with non-Lowrance systems? It is designed to connect over NMEA 2000. If your system can receive the relevant NMEA 2000 data and you have network integration, it may work in principle, but compatibility depends on your specific display and NMEA 2000 setup.
Does it provide heading or just GPS location? It provides both position and heading. The integrated electronic compass is intended to support direction information and chart/radar overlay stabilization.
Is it waterproof and how is it mounted? Yes, it is fully waterproof. It supports pole or surface mounting, and the box includes mounting hardware and a gasket seal.
What update rate does it use? The feature set describes 10 Hz updates for smooth and accurate location and heading behavior.
Is it compatible with MARPA radar functionality? It is not recommended for use with MARPA functionality of radar.
What Lowrance displays is it meant for? It’s listed as connecting to Lowrance HDS LIVE, HDS Gen2, HDS Gen2 Touch, and Elite-7 displays, and it can also connect to any NMEA 2000 network.
