Navico B60 Thru-Hull 12-Degree 9-Pin XSONIC Connector

Upgrade your vessel's underwater detection with the precision-engineered B60 thru-hull transducer, designed for boaters who demand reliable depth and temperature readings in diverse marine environments. This bronze-housed unit punches through hulls up to several inches thick, delivering crystal-clear sonar imagery that helps you navigate shallow waters, track fish schools, and monitor bottom structure with confidence.

Exceptional Performance in Real-World Conditions

Crafted from high-grade bronze, this transducer withstands the harsh saltwater environment while maintaining acoustic integrity. Operating at dual frequencies—50 kHz for wide-area coverage in deeper waters and 200 kHz for high-resolution details in shallower zones—it adapts seamlessly to your boating needs. The 12-degree beam angle at 50 kHz provides a focused scan that's ideal for offshore fishing or coastal cruising, minimizing clutter from surface noise and thermoclines.

Boaters often praise its sensitivity to subtle bottom changes, like rocky ledges or drop-offs, which can make all the difference during structure fishing. In choppy seas, its stable thru-hull mounting reduces interference, ensuring consistent data feeds to your chartplotter or fishfinder. Pair it with modern multifunction displays, and you'll unlock detailed water column views that reveal baitfish suspensions and predator movements.

Key Features That Set It Apart

• Dual-Frequency Versatility: Switch between 50 kHz (wide cone for broad searches) and 200 kHz (narrow cone for pinpoint accuracy), covering depths from a few feet to over 1,000 feet depending on conditions.
• Built-In Temperature Sensor: Provides real-time water temp data to correlate with fish behavior, helping you target species like tuna or snapper during seasonal migrations.
• 600W Power Handling: Delivers strong signal returns even in murky or sediment-heavy waters, outperforming lower-wattage alternatives in low-visibility scenarios.
• 9-Pin XSONIC Connector: Plug-and-play compatibility with a range of marine electronics, simplifying integration without adapters.
• 12-Degree Beam Angle: Optimized for hull speeds up to 30 knots, balancing coverage and resolution for trailerable boats to mid-size cruisers.

Installation Insights for Optimal Results

Mounting a thru-hull transducer like this one requires careful planning to avoid air pockets or flow distortion. Position it forward of the propellers and strakes, ideally on the centerline or slightly offset for single-engine setups. Use a fairing block to align it parallel to the waterline at displacement speeds—this maximizes bottom lock and reduces cavitation noise.

For fiberglass or wooden hulls, drill a clean hole and bed the unit in marine sealant for a watertight seal. Aluminum or steel hulls benefit from isolation mounts to prevent electrolysis. Once installed, run a self-test on your display to verify signal strength; fine-tune deadrise angle if needed for dead reckoning accuracy. Many users report DIY installs taking under two hours with basic tools, but professional fitting ensures longevity in rough-water applications.

Why Choose Bronze Construction?

Bronze isn't just durable—it's acoustically superior, transmitting sonar pulses with minimal attenuation compared to plastic housings. This translates to sharper echoes and fewer false readings from hull material interference. In tropical or brackish waters, its corrosion resistance outshines stainless alternatives, making it a favorite for long-range expeditions or liveaboard setups.

Perfect for Anglers, Divers, and Navigators

Whether you're trolling for pelagics, bottom bouncing for grouper, or plotting safe passages through uncharted reefs, this transducer elevates your situational awareness. Kayak anglers adapt it for custom mounts, while offshore charters rely on its temp gradients to locate upwellings teeming with life. Divers appreciate the precise depth logs for planning descent profiles.
