Raymarine B265LH 1kW Bronze Thru Hull w/Temp

Unlock Crystal-Clear Underwater Insights with the Raymarine B265LH

Imagine gliding through open waters, pinpointing massive bait balls and rugged bottom structures from depths that lesser transducers can't touch. The Raymarine B265LH 1kW Bronze Thru-Hull Transducer with integrated temperature sensor delivers exactly that—professional-grade sonar performance tailored for dedicated offshore anglers and navigators who demand precision without compromise.

Crafted from robust bronze, this thru-hull design mounts seamlessly below the waterline, ensuring consistent signal transmission even in rough seas. Its 1kW power handling punches through water columns up to extreme depths, revealing details that help you hook more fish and navigate safer.

Advanced CHIRP Technology for Superior Target Separation

At the heart of the B265LH lies Raymarine's cutting-edge CHIRP (Compressed High-Intensity Radar Pulse) technology. Unlike traditional fixed-frequency sonar, CHIRP sweeps across wide frequency bands, producing sharper images with exceptional target separation. This means distinguishing individual fish in a school, spotting wrecks hidden in the abyss, or mapping subtle contour changes on the seabed.

• Dual-Channel Operation: Low-frequency band (42-65 kHz) excels at deep-water penetration for tracking game fish like tuna or swordfish. High-frequency band (130-210 kHz) shines in shallower zones, highlighting baitfish and structure with fine resolution.
• Integrated Temperature Sensor: Real-time water temp readings help locate thermoclines—those hidden temperature layers where fish congregate—giving you an edge in strategic positioning.
• Bronze Construction: Corrosion-resistant and built to withstand the harshest marine environments, from saltwater spray to constant submersion.

Whether you're chasing pelagics in the bluewater or bottom bouncing for snapper, the B265LH transforms your display into a window to the underwater world.

Effortless Installation and Rock-Solid Compatibility

Mounting a thru-hull transducer like the B265LH requires careful planning, but its straightforward design simplifies the process for skilled installers. Position it forward of the prop and keel for optimal beam coverage, ensuring the hull's deadrise angle falls within the recommended range (up to 25 degrees) to minimize air bubble interference.

Pair it with Raymarine multifunction displays and sounder modules that support high-power CHIRP. It integrates flawlessly, unlocking features like Fishman MAP, DownVision, and SideVision when combined with compatible CP or RV units. For DIY enthusiasts, fairing blocks are available to streamline water flow and enhance performance on planing hulls.

Pro Tip: Always bed the transducer in a marine sealant to prevent water ingress, and route cables away from electrical noise sources for clean, interference-free sonar returns.

Why Serious Boaters Swear by the B265LH

This isn't just another sonar probe—it's a game-changer for those who fish professionally or push their vessels to the limits. Boaters report 30-50% better deep-water resolution compared to standard 600W units, with the temp sensor proving invaluable for troll-and-search tactics.

In competitive fishing circuits, its wide beam coverage (up to 40 degrees low freq) sweeps vast areas efficiently, while the narrow high-freq beam drills down for precision targeting. Saltwater pros appreciate the bronze alloy's longevity, outlasting plastic alternatives in abrasive conditions.

Real-World Applications for Every Angler

From canyon runs targeting yellowfin to reef hopping for grouper, the B265LH adapts to your pursuit. Tournament captains use it to mark spots with unmatched detail, while cruisers rely on its temp data for safer passages through variable conditions. Its thru-hull permanence beats portable puck-style units for consistent hull speed readings.
