Description
Garmin GMR 436 xHD3 Radar
The Garmin GMR 436 xHD3 Radar clarifies offshore navigational mapping by resolving target density issues through high-definition 4kW pulse transmission. This 6-foot open array system safeguards the vessel by narrowing the horizontal beamwidth to 1.1 degrees, identifying distant bird flocks and small hazards that smaller antennas miss during long-range transits in US coastal waters.
Integrated via the Garmin Marine Network, the GMR 436 hardware utilizes 8-bit true color to distinguish target intensity and reduce signal noise. The pedestal facilitates scan-to-scan averaging and dual-range scanning, ensuring that the navigation network provides consistent, high-fidelity environmental data for safe maneuvers in congested shipping lanes and unpredictable weather.

Garmin GMR 436 xHD3 4kW Radar Guide
The GMR 436 pairs a 4kW high-definition pedestal with a 6-foot array, providing a narrow 1.1-degree beamwidth for the highest possible resolution in a 4kW class.
New to the xHD3 magnetron series, Scan Averaging filters out sea clutter and interference, making small targets like buoys or birds much easier to identify.
This 4kW system provides a reliable 72 nautical mile range, offering a great balance of long-range visibility and energy efficiency for offshore cruisers.
Yes, it features True Echo Trails, which display a fading history of a target's movement, allowing the captain to quickly assess vessel direction and speed.
Yes, it is fully Garmin Marine Network compatible and integrates seamlessly with current-generation GPSMAP multifunction displays via a simple Ethernet connection.
