Lowrance B285H-W High Wide Bronze Thru-Hull 9-Pin

Unlock Superior Coverage with the High-Wide CHIRP Advantage

Imagine scanning vast areas beneath your hull with pinpoint precision, spotting schools of fish that narrower beams might miss entirely. The B285H-W transducer delivers exactly that through its innovative high-wide design, blending broadband CHIRP technology with a consistent 25-degree beamwidth across the full 150-250 kHz range. This isn't just about wider scans—it's about transforming your sonar display into a clearer, more revealing window into the underwater world.

For serious anglers chasing everything from coastal stripers to offshore pelagics, this thru-hull powerhouse doubles the bottom coverage compared to traditional high-frequency options. The result? Larger, sharper fish arches and bottom details that pop on screen, even in the upper water column where subtle targets hide. Whether you're navigating structure-packed bays or open water, the constant beam angle ensures reliable performance without the drop-off in coverage at higher frequencies.

Key Features That Set It Apart

• Broadband Excellence: Sweeps 150-250 kHz for versatile target separation and resolution in varying depths.
• Wide Beam Consistency: Maintains a full 25° beamwidth across the band, providing expansive coverage without compromise.
• Bronze Thru-Hull Build: Durable construction resists corrosion in saltwater environments, with a streamlined shape for minimal drag.
• 9-Pin Connectivity: Seamless integration with modern fishfinder systems supporting CHIRP protocols.
• Enhanced Imaging: Produces crisp, amplified returns that make fish and structure stand out vividly.

Why Wide Beam CHIRP Changes Your Fishing Game

Narrow-beam transducers excel at deep-water detail, but they often leave gaps in shallow or mid-range scans. Enter the high-wide format: it floods more water under your boat, ideal for quickly locating bait balls, marking wrecks, or prospecting new grounds. Anglers report easier hookups on suspended fish, as the broader beam catches returns from off-angle targets that slip past conventional setups.

In real-world use, pair this with medium CHIRP sweeps for layered coverage—high-wide for search and locate, low for deep structure. The bronze housing thrives in harsh marine conditions, and its thru-hull mount keeps the element flush for clean hydrodynamics and zero interference from hull slap. Pro tip: Position it forward and slightly off-center to avoid prop wash distortion, maximizing clean pings.

Installation Insights for Peak Performance

Thru-hull mounting demands precision, but the rewards are unmatched waterline clarity. Select a flat hull section below the waterline, ideally amidships for balanced readings. Use marine sealant around the thru-hull fitting to prevent leaks, and route the 9-pin cable away from high-voltage lines to dodge noise. Once bedded in, calibrate your unit's settings to leverage the full CHIRP spectrum—start with wide beam modes for scouting, then zoom in.

Maintenance is straightforward: Rinse with fresh water after saltwater runs, inspect the face for growth, and store dry in off-seasons. This transducer's rugged design holds up season after season, delivering consistent results that keep you ahead of the fish.

Perfect Scenarios for High-Wide Dominance

Inshore and Nearshore: Excel at reef hunting or trolling live bait, where wide coverage reveals hidden potholes teeming with snapper.

Lake and River Fishing: Spot crappie suspensions or bass staging on ledges with superior upper-water clarity.

Tournament Edge: Rapid area scans save time, letting you focus on setting lines while rivals pixel-hunt narrow views.

Elevate your electronics setup with this transducer, and watch your catch rates—and confidence—soar. It's engineered for those who demand more from their sonar.
