Description
Furuno DRS4DNXT – 24-Inch NXT Solid State Doppler Radar (No Cable)
Solving the need for advanced hazard detection, the Furuno DRS4DNXT is a 24-inch solid-state radome featuring revolutionary NXT Doppler technology. This radar is specifically designed for American offshore anglers who demand instant identification of moving targets. For the USA captain, the Target Analyzer function automatically changes the color of approaching targets to red, providing an immediate visual warning of potential collisions in busy shipping lanes or fogs. Its high-resolution “Bird Mode” is a game-changer for the Atlantic and Gulf coasts, allowing fishermen to track bird schools and find the most productive tuna and mahi-mahi grounds with surgical precision.
The DRS4DNXT utilizes a fanless, solid-state design for extreme reliability and instant-on capability without the traditional magnetron warm-up time. With its compact 24-inch footprint and advanced RezBoost beam sharpening, it delivers the target separation of a much larger open-array antenna. This model offers the American maritime market a sophisticated, low-maintenance radar solution that excels in situational awareness and elite-level fish finding.

Common Questions for Furuno DRS4DNXT
The DRS4DNXT requires a DC power supply that meets minimum marine cranking amps to ensure the Doppler processing remains stable. Although it lacks a gallons per hour rate, the Furuno DRS4DNXT Radar provides 25W of pulse compression power, which is equivalent to a much higher-rated traditional magnetron radar.
A 24-inch radome is the optimal boat hull application for offshore anglers who need Bird Mode and Target Analyzer technology. The Furuno Solid State Radar identifies hazardous targets by changing their color to red, allowing the Furuno DRS4DNXT user to focus on fishing while the radar handles collision avoidance.
Verify that your vessel's sacrificial aluminum anode locations are intact to prevent stray current from affecting the radar’s base. Maintaining the Furuno DRS4DNXT NXT involves wiping the dome with fresh water to remove salt spray, which prevents signal degradation and ensures the Doppler sensors remain highly accurate.
The DRS4DNXT is sold without a cable to allow for custom lengths; however, you must source Genuine Furuno Parts for the installation. The Furuno DRS4DNXT Antenna requires specialized shielded wiring to support its high-speed data transfer and RezBoost beam sharpening technology, which provides the target clarity of an open array.
This solid-state radar uses a maintenance-free brushless motor and does not have an FC-W engine oil capacity or any gears that require lubrication. The Furuno 24-Inch NXT Radar is engineered for a long, zero-maintenance life cycle, offering instant-on capability and reliable performance without the mechanical wear of traditional systems.
