GMR™ 2536 xHD3, 6-foot open-array radar and 25 kW pedestal

The Garmin GMR 2536 xHD3 radar provides target detection from 20 meters to 96 nautical miles.

The GMR 2536 xHD3 radar antenna is a 6-foot open-array antenna, which is approximately 183 centimeters.

The GMR 2536 xHD3 radar integrates several advanced technologies to enhance target detection and image clarity:

Scan Averaging: This technology, a first for Garmin magnetron radars, filters sea clutter and interference for improved target detection. Angular adjustment of target size: This function uses pulse expansion and angular size processing to optimize the shape of objects on screen, making them easier to interpret across all range scales. True Echo Trails: This feature displays a history of vessel tracks, helping to identify moving targets and improve situational awareness.

The GMR 2536 xHD3 radar antenna can operate at rotation speeds of 24 and 48 revolutions per minute (RPM), ensuring rapid display refresh.

The GMR 2536 xHD3 radar has a horizontal beam width of 1.1 degrees, which contributes to a clear and detailed image resolution.

The Garmin GMR 2536 xHD3 radar is a 25 kW open-array system.

Yes, the Garmin GMR 2536 xHD3 radar is designed specifically for offshore navigation and fishing, providing advanced target detection in various conditions.

When selecting the mounting location, it is essential to consider the following points:

The radar must be mounted out of reach of people, with the vertical beam above head height. It must be installed high above the vessel’s keel line, with minimal obstruction of the radar beam. The mounting surface must be flat, parallel to the vessel’s waterline, and sufficiently robust to support the radar’s weight. The location must allow for connection to power, ground, and the network. The radar must be mounted away from heat sources (exhausts, lights) and at a different level from horizontal spreaders and mast crossarms. To avoid interference, it must be mounted at least 2 m (6.5 ft) from other electronic equipment and cables, and at least 1 m (40 in) from transmitters or radio cables. GPS antennas must be positioned above or below the radar beam path. A minimum distance of 2 m (6.5 ft) is required from HF radios (SSB).

When installing cables, the following points must be observed:

A 32 mm (1 1/4 in) diameter hole may be required for cable routing; apply marine sealant around this hole after cables are installed to ensure watertight integrity. Use appropriate cable ties, fasteners, and sealant to secure the cable along its route and through bulkheads or the deck. Avoid routing cables near moving objects, high-heat sources, or through doors and lockers. To prevent interference, do not run network and power cables parallel to other cables (radio antenna lines or power cables). If unavoidable, these cables must be shielded with a metal conduit or other EMI shielding. Power cables should be installed as close as possible to the battery source.

The ground cable is not included with the GMR 2536 xHD3 radar. It must be connected to a water ground, not to the battery's negative terminal.

If your model is supplied with a voltage converter:

Run the power cable to the radar and the voltage converter. Use crimp connectors and heat-shrink tubing to connect the power cable to the voltage converter. The radar’s power cable includes a 15 A fuse that must not be removed. Connect the voltage converter to the boat’s battery via the included 30 A fuse. Both fuses (15 A in the radar cable and 30 A between the converter and the battery) must be in place for proper operation. Connect the power cable to the radar’s POWER port. It is recommended to install the voltage converter as close as possible to the power source and connect it directly to the battery.

Yes, the GMR 2536 xHD3 radar is designed to be compatible with Garmin BlueNet™ and Garmin Marine Network networks. The connection port is provided for both network types.

The GMR 2536 xHD3 radar power converter requires an input voltage of 10 to 32 Vdc to operate correctly.

The Garmin GMR 2536 xHD3 radar is an open-array 25 kW system designed specifically for offshore navigation and fishing. It provides advanced target detection, whether for weather conditions, obstacles, or maritime traffic, over an impressive range from 20 meters to 96 nautical miles. This model features a 6-foot (183 cm) antenna and a 1.1-degree horizontal beam width, ensuring clear and detailed image resolution for improved situational awareness.

The GMR 2536 xHD3 integrates several advanced detection technologies to optimize performance and image clarity. It uses Scan Averaging technology, a first for Garmin magnetron radars, which effectively filters sea clutter and interference to improve target detection. The angular size adjustment function for targets uses pulse expansion and angular size processing to optimize object shape on screen, making interpretation easier across all range scales. Additionally, True Echo Trails display a history of vessel trajectories, helping to identify moving targets. Rotation speeds of 24 and 48 RPM ensure rapid display refresh.

Connecting the GMR 2536 xHD3 radar to the power supply depends on your installation setup:

With a voltage converter (if provided): The converter requires an input voltage of 10 to 32 VDC and must be installed as close as possible to the power source. The radar's power cable includes a 15 A fuse that must not be removed. The converter must be connected to the boat's battery via a 30 A fuse (included). Both fuses (15 A and 30 A) must be in place for proper operation.

Direct connection (if the converter is not provided): The radar can be connected directly to the boat's battery with an input voltage of 11 to 32 VDC. The radar's power cable includes a 15 A fuse that must not be removed.

Note that using a voltage converter, even if not provided, may allow the radar to better withstand stronger winds.

In both cases, direct connection of the power cable to the battery is recommended. A ground cable (not included) must be connected to a water ground, not to the battery's negative terminal.

The Garmin GMR 2536 xHD3 radar is designed to integrate seamlessly with Garmin marine network systems. It is compatible with the Garmin BlueNet™ network as well as the standard Garmin marine network. This compatibility ensures smooth interconnection with other compatible Garmin devices aboard your vessel, enabling data sharing and a unified navigation experience.
