Furuno DRS25AX 25kW UHD Digital Radar 3.5 ft Open Array 15M Cable

The Furuno DRS25AX 25kW UHD Digital Radar with 3.5-foot Open Array, Pedestal, and 15M Cable (MPN DRS25AX/3) is Furuno's X-Class magnetron radar flagship, designed for serious offshore cruising, commercial-traffic operation, and long-range weather detection on NavNet TZtouch, TZtouch2, and TZtouch3 helms. The package includes the redesigned pedestal unit (20 percent lighter than previous Furuno generations), the 3.5-foot open-array antenna, and a 15-meter smart-connector cable for the mast-to-helm run.

What 25 kilowatts of magnetron output actually does. Output power directly determines maximum detection range on small targets, signal-to-noise performance through heavy weather, and the ability to resolve small targets at distances where they matter for collision avoidance and weather routing. At 25kW the DRS25AX reaches the practical detection ranges that smaller radars can't, sees through rain and weather that washes out lower-power systems, and resolves small targets at distances where they actually matter operationally. For commercial-vessel-class detection performance from a recreational-class Furuno helm, 25kW magnetron is the right technology.

X-Class architecture. Furuno's X-Class radar line pushes the boundaries of what's possible with conventional magnetron radar technology. Improved in almost every aspect over previous Furuno generations, including better short-range detection (down to a 20-meter minimum range), better long-range detection (up to 96 nautical miles), a redesigned pedestal that's 20 percent lighter, an updated low-noise drive motor, and the smart-connector cable that simplifies install and maintenance. The X-Class isn't a refresh, it's a redesign with operational improvements end-to-end.

Fast Target Tracking. The DRS25AX adopts Fast Target Tracking technology from Furuno's commercial FAR3000 radar series. Target course and speed vectors are displayed instantly with the press of a button, no waiting for multiple sweeps to compute the track. For collision avoidance in busy waters, the instant vector display turns radar from passive return-watching into active threat assessment. You see where each target is going, not just where it is right now.

Bird Mode. Performance-tuned detection for locating sea birds working bait, with optimized gain and sea clutter settings that distinguish birds from sea-state noise. For offshore sport-fishing operations where bird sightings are the lead indicator for finding bait balls and fish, Bird Mode turns the radar into a fishing instrument. Older radars made you squint at clutter, Furuno's Bird Mode shows you the birds.

3.5-foot open-array antenna. The antenna size determines beamwidth, and beamwidth determines target separation. The 3.5-foot antenna delivers a narrow horizontal beam that resolves two targets at slightly different bearings as two distinct returns instead of merging them. For commercial-traffic operation, weather routing, and any use where you need to distinguish multiple targets in proximity, the 3.5-foot is the antenna size that justifies the open-array architecture.

Reduced minimum detection range. The DRS25AX detects targets down to 20 meters minimum range, which is genuinely operational for harbor approaches and close-quarters maneuvering. Older 25kW magnetron radars struggled to see anything closer than 50-100 meters because the magnetron transmit pulse fundamentally limits near-field resolution. Furuno's X-Class signal processing closes that gap, so you have the same radar covering distant traffic at 96nm and close-in obstacles at 20m without switching to a separate close-range sensor.

Updated pedestal design. The redesigned pedestal is 20 percent lighter than previous Furuno 25kW generations, which matters for mast structural loading and high-wind operation. The updated drive motor runs significantly quieter, so the radar isn't a noise source at the helm or in the master cabin below the mast. The smart-connector cable simplifies install and maintenance, you don't have to open the pedestal unit to make the cable connection. And no separate power supply unit is required, which reduces total install cost and electrical complexity.

Integration. The DRS25AX is designed for the NavNet TZtouch, TZtouch2, and TZtouch3 multifunction display platforms. Full integration includes radar overlay on chart, ARPA target tracking, Fast Target Tracking vector display, Bird Mode and other operating modes, and standard radar controls operating through the TZtouch interface. Not compatible with the older NavNet 3D or earlier NavNet generations, this is a current-generation Furuno helm radar.

Install considerations. The 3.5-foot open array and 25kW pedestal require structural mounting on a mast, radar arch, or hardtop with adequate support for the antenna assembly, rotating mass, and pedestal weight (still significant despite being 20 percent lighter than previous generations). The 15-meter smart-connector cable routes between the mast and the below-deck network connection. The DRS25AX is a 24V DC system, so 12V boats need a converter for the radar supply. Total install is a marine electronics installer day-plus for a clean job. Not casual DIY because the mast mount, cable routing, voltage conversion if needed, and TZtouch commissioning all benefit from professional setup.

Why pay this much. Three reasons. First, 25kW magnetron power delivers maximum detection range and weather penetration in a recreational-class Furuno helm radar. Second, X-Class architecture delivers improvements end-to-end (lighter pedestal, quieter motor, smart cable, no PSU, 20m minimum range), which are operational quality-of-life improvements that matter daily, not just on the spec sheet. Third, Fast Target Tracking and Bird Mode turn raw radar capability into operationally useful tools for collision avoidance and offshore sport fishing. For owners running or building a Furuno NavNet TZtouch helm where serious radar capability is the requirement, the DRS25AX 3.5-foot is the radar that earns its position.
