Upgrade your marine sonar system with the powerhouse performance of the Raymarine R109LH-W CHIRP transducer. Designed for serious anglers and boaters who demand crystal-clear underwater imaging, this thru-hull mount unit delivers exceptional depth penetration and target separation across a wide range of fishing environments. Whether you're chasing deep-water species or scanning shallows for structure, its dual-frequency CHIRP technology ensures you never miss a mark.

What sets this transducer apart is its robust construction and optimized beam patterns. The low-frequency range punches through to extreme depths, while the high-frequency wide beam offers superior coverage for bait schools and bottom details in shallower zones. Paired with its integrated temperature sensor, you'll gain valuable insights into water conditions that can make or break your day on the water.

Key Performance Advantages

Thru-hull mounting positions the ceramics directly in contact with the water, eliminating air pockets or hull interference that plague transom-mount alternatives. This results in sharper echoes, reduced noise, and reliable readings even at high speeds. The wide beam design on the high-frequency band expands your search area, making it ideal for trolling or drifting over reefs and wrecks.

• Superior Depth Capability: Reach up to 6,000 feet on low frequencies for offshore adventures.
• Versatile Frequency Sweep: Low band (38-75 kHz) for power; high band (150-250 kHz) for precision.
• Beam Flexibility: Narrow low beam for targeting, wide high beam for coverage, accommodating hull deadrises up to 25 degrees.
• Built to Last: Rugged housing withstands harsh marine conditions, backed by reliable engineering.

Boaters report enhanced target resolution, spotting fish hiding near structure or thermoclines with ease. Its 2kW power rating supports demanding applications on larger vessels, ensuring consistent performance without signal dropouts.

Real-World Applications

From coastal jigging to bluewater trolling, this transducer shines in diverse scenarios. In shallow bays, the expanded high-frequency beam reveals subtle contours and baitfish congregations that standard units overlook. Venture offshore, and the low CHIRP frequency maintains lock-on with pelagics at cruising depths. Integrated temp sensing helps identify productive water columns, correlating surface temps with underwater activity for smarter lure choices.

Anglers appreciate how it minimizes clutter from bait balls, isolating individual fish for confident hooksets. Pair it with modern multifunction displays, and you'll unlock advanced features like bottom discrimination and water column analysis, elevating your fishing game.

Effortless Integration and Maintenance

Installation is straightforward for those familiar with thru-hull fittings—fair the housing to match your hull angle for optimal water flow. The compact 6.6-foot cable reaches most helm stations without extensions. Regular maintenance involves simple hull cleaning and ceramic checks to preserve peak sensitivity. Its durable molded design resists fouling and impact, reducing long-term upkeep.
