Upgrade your vessel's radar system with the Furuno RSB134-114 25kW gearbox, the heart of the powerful DRS25AX open array radar. Designed for serious mariners who demand precision and reliability on the water, this gearbox delivers exceptional performance whether you're navigating busy coastal waters or scanning horizons for distant targets during offshore adventures.

Crafted with cutting-edge engineering, the RSB134-114 gearbox enhances the DRS25AX's capabilities, offering sharper short-range detection down to just 20 meters—ideal for avoiding close-quarters hazards like buoys or small craft. At the same time, it pushes long-range performance to an impressive 96 nautical miles, giving you unmatched situational awareness for safe passage planning.

Key Advantages for Everyday Boating

• Powerful 25kW Output: Cuts through rain, fog, and clutter for clear echoes on targets big and small.
• Fast Target Tracking™: Borrowed from Furuno's professional FAR3000 series, this feature instantly displays target vectors for course and speed, boosting safety during high-traffic maneuvers.
• Bird Mode: Spot seabirds from afar to locate bait schools, a game-changer for anglers chasing trophy fish.
• Lighter and Quieter Design: The redesigned pedestal sheds 20% of its previous weight and runs with a whisper-quiet motor, reducing vibration and noise for a more comfortable onboard experience.
• Cost-Saving Simplicity: No separate power supply unit needed, and the innovative smart-connector cable makes setup straightforward without opening the unit.

Boat owners love how this gearbox transforms radar into a proactive tool. Imagine tracking a pod of migrating fish or monitoring approaching squalls with crystal clarity— that's the edge the RSB134-114 provides.

Seamless Integration and Compatibility

Pair this gearbox with 3.5-, 4-, or 6-foot open array antennas for customizable beam widths: from 2.3° horizontal for broad coverage to a pinpoint 1.4° on the largest array for ultra-fine detail. It's optimized for 24VDC systems, common on larger vessels, but pairs easily with a converter for 12V setups.

Works flawlessly with Furuno's NavNet TZtouch and TZtouch2 multifunction displays, unlocking advanced overlays like radar-on-chart and ARPA-like tracking. Skip older NavNet 3D models for full X-Class features— this is built for modern networks.

Quick Installation Insights

Engineers at Furuno prioritized user-friendliness: the smart-connector simplifies wiring, and the pedestal mounts securely without disassembly. Most skippers complete setup in under an hour, using the included corrosion-proof pads and hardware for rock-solid stability in rough seas. Pro tip: Align the array precisely north during calibration for optimal heading data.
