Furuno DRS4DNXT Doppler Radar – No Cable

Description

The Furuno DRS4D-NXT Doppler Radar is a 24-inch solid-state pulse-compression radar radome for compatible Furuno NavNet TZtouch, TZtouch2, and TZtouch3 multifunction displays. It combines Target Analyzer Doppler processing, Fast Target Tracking, Bird Mode, and RezBoost beam sharpening in an enclosed radar scanner. This version is supplied without a radar cable, so a compatible Furuno 12-pin signal cable and the required power and Ethernet connections must be selected separately.

The DRS4D-NXT provides 25W solid-state output and a maximum instrumented range of up to 36 NM. Its 24-inch radome has a typical 3.9-degree horizontal beamwidth, which can be narrowed through RezBoost processing in supported display configurations. Practical radar detection and target tracking depend on mounting height, target size, display configuration, heading data, sea state, weather, radar settings, and local interference.

Key Specifications

• Twenty-four-inch Furuno solid-state pulse-compression Doppler radar radome.
• Uses 25W solid-state output with Target Analyzer Doppler, Fast Target Tracking, Bird Mode, and RezBoost support.
• Provides a maximum instrumented range of up to 36 NM.
• Uses a typical 3.9-degree horizontal beamwidth, adjustable to an effective 2-degree beamwidth with RezBoost in supported configurations.
• Supports 24, 36, and 48 RPM rotation speeds, with dual-range operation limited to 24 RPM.
• Requires a compatible Furuno NavNet TZtouch, TZtouch2, or TZtouch3 MFD and Furuno Ethernet radar network.
• Operates from 12V or 24V DC and weighs approximately 7.3 kg.
• Does not include the required compatible 12-pin signal cable, power cable, radar display, mount, heading sensor, or GPS source.

Radar Integration

The DRS4D-NXT requires a compatible Furuno NavNet MFD for radar video display and scanner control. Radar video uses Furuno Ethernet; NMEA 2000 can provide compatible heading, GPS, AIS, autopilot, and sensor data but does not carry radar video. Confirm the required 12-pin signal cable, available MFD Ethernet port, power cable, software version, and full network configuration before purchase.

Target Analyzer Doppler can help distinguish approaching and receding targets, while Fast Target Tracking and Bird Mode depend on compatible display functions and radar configuration. Radar overlay and target tracking require compatible heading and position data where applicable. Radar is a navigation aid and does not replace a proper lookout, safe speed, official charts, local notices, or collision-regulation compliance.

Installation Considerations

Mount the 24-inch radome on a rigid stable platform with unobstructed scanner rotation, practical elevation above the waterline, and alignment parallel to the waterline. Keep it clear of crew areas, masts, antennas, lights, exhaust, rigging, and other obstructions. Maintain manufacturer-specified personnel safe distance and compass-safe distance. Select and route the required power and 12-pin signal cables away from heat, chafe, bilge water, high-current wiring, and moving equipment. Radar installation and commissioning should be completed by a qualified marine-electronics technician.

Warranty and Saltwater Care

Furuno warranty coverage varies by region, distributor, proof of purchase, product registration, installation method, commissioning status, and intended use. Confirm applicable local warranty terms, exclusions, and authorized-service requirements before purchase.

The radome is designed for marine exposure, but its protection rating does not guarantee immunity from saltwater corrosion. Rinse salt deposits with fresh water where appropriate, avoid direct high-pressure water at cable glands and connectors, inspect the radome base, fasteners, seals, signal-cable connection, and mounting platform regularly, and use compatible marine-grade hardware plus isolation methods to reduce galvanic-corrosion risk.

Before Ordering

Confirm compatible Furuno NavNet TZtouch, TZtouch2, or TZtouch3 MFD support, required 12-pin signal-cable and power-cable lengths, Furuno Ethernet radar network, 12V or 24V supply, suitable radome mount, clear 24-inch scanner rotation area, mounting height, personnel and compass-safe-distance requirements, heading and GPS source for overlay or tracking, optional AIS integration, and qualified installation requirements before purchase.
