Upgrade your vessel's sonar capabilities with a transducer that delivers pinpoint accuracy in even the trickiest waters. Boaters who demand reliable depth readings and precise water temperature data turn to this robust bronze thru-hull sensor for its no-nonsense performance. Crafted for serious anglers, cruisers, and commercial operators alike, it cuts through interference to provide clear, actionable insights right when you need them most.

Why This Thru-Hull Transducer Stands Out on the Water

Imagine gliding through shallow bays or navigating rocky coastlines without second-guessing your sounder. This sensor's 235 kHz frequency paired with a tight 12-degree beamwidth hones in on bottom structure and fish targets with exceptional detail, especially in depths under 500 feet. The digital signal processing minimizes clutter from boat wakes or thermoclines, giving you a cleaner display on your Furuno chartplotter or fishfinder.

Bronze construction laughs off saltwater corrosion, ensuring years of trouble-free service in harsh marine environments. Unlike plastic alternatives that can warp or degrade, this housing maintains its shape for consistent acoustic performance. And with integrated high-precision temperature sensing—accurate to within one degree—you'll spot bait balls shifting with thermal layers or time your lure changes perfectly for surface conditions.

Key Performance Specs That Deliver Real Results

• Power Output: 200 watts of clean power for strong returns without overwhelming your display.
• Frequency: Optimized 235 kHz for shallow-to-midrange scanning with superior target separation.
• Beam Angle: Narrow 12-degree cone for detailed bottom mapping and fish arching.
• Cable: 10 meters (32.8 feet) of rugged, shielded cabling with a secure 7-pin connector for easy integration.
• Housing: Low-profile Airmar B17-style bronze thru-hull, 3.49 inches long with a 2-inch diameter shaft for minimal drag.

Seamless Installation for DIY or Pro Setups

Mounting is straightforward for thru-hull applications: Drill a clean hole at or below the waterline, bed the sensor in marine sealant, and secure it with the included nut. Deadrise angles up to 12 degrees won't faze it—its design compensates for hull slopes common on planing hulls. Connect to compatible Furuno units via NMEA 0183 output for plug-and-play depth, temp, and speed data sharing across your network. Pro tip: Fair the leading edge slightly to reduce turbulence and boost signal quality at speed.

Proven in Real-World Boating Scenarios

Offshore anglers praise its ability to pick out structure in 100-300 feet amid bait schools, while inland lake enthusiasts appreciate the crisp separation on flats. Sailors value the temp sensor for monitoring engine cooling water or spotting upwellings. Even in rough seas, the digital tech filters out aeration noise, keeping your readings steady when others falter. It's a workhorse that elevates everyday outings into confident adventures.

Long-Term Reliability and Maintenance Essentials

Built to last with a corrosion-resistant bronze body, it shrugs off barnacle buildup better than competitors. Routine care is simple: Wipe clean after use, inspect the face for marine growth, and avoid antifouling paints on the active element. Backed by Furuno's commitment to quality, it holds up through seasons of heavy use, minimizing downtime and repair hassles.
