Dual-Frequency CHIRP: Low (38-75 kHz) for deep-water tracking up to 8,000 ft; High Wide (150-250 kHz) with a constant 25° beam for enhanced shallow-water coverage.
High Power: 2 kW output ensures crisp target detail and high-resolution imaging at all depths.
Wide-Beam Technology: 25° beam width in high-frequency mode doubles coverage for detecting fish and bait in shallow waters.
Robust Design: Plastic housing with fairing block and 16 broadband ceramics, suitable for multiple hull types.
The Garmin Airmar R109LHW is a high-performance, plastic thru-hull CHIRP transducer designed for deep-sea fishing and large vessels 30 feet and above. Featuring dual-frequency CHIRP capabilities—Low (38-75 kHz) and High Wide (150-250 kHz)—it delivers exceptional depth penetration up to 8,000 feet and wide-beam coverage for shallow-water performance. With a 2 kW power output, it provides excellent target separation and image resolution, ideal for distinguishing baitfish from game fish. Equipped with 16 internal broadband ceramics, a high-performance fairing block, and a built-in temperature sensor, it’s compatible with Garmin GSD 26 sonar modules and select GPSMAP chartplotters. The R109LHW is designed for fiberglass, wood, or metal hulls with 0°-25° deadrise, making it a top choice for serious offshore anglers and commercial vessels targeting deep-water species.

Sonar Capabilities: Dual-channel CHIRP with Low (38-75 kHz, 9°x23° beam width) for deep-water bottom tracking and High Wide (150-250 kHz, constant 25° beam width) for broad coverage and precise fish detection in shallow waters. Excellent separation of baitfish and game fish.
Performance: 2 kW power with 16 internal ceramics provides high sensitivity and clarity, ideal for detecting deep structures and fish schools.
Compatibility: Works with Garmin GSD 26 sonar module and compatible chartplotters (e.g., GPSMAP 8400/8600, 7×3/9×3/12×3 series). Requires bare wire connection; not compatible with Furuno displays like FCV-295 without a specific Furuno version (e.g., Airmar R109C-LHW).
Installation: Thru-hull mount with high-performance fairing block for hulls with 0°-25° deadrise. Includes 49 ft (15 m) bare wire cable for flexible installation. Professional installation recommended due to 2″ hull cutout and 35 lb weight.
Additional Features: Built-in fast-response water temperature sensor; Xducer ID® technology for automatic sonar tuning and transducer recognition.
Applications: Ideal for offshore sportfishing and commercial vessels targeting deep-water species like tuna, swordfish, or bottom fish in depths up to 8,000 ft.
Construction: Durable plastic housing with epoxy/urethane coating, designed for fiberglass, wood, or metal hulls. Fairing block ensures proper alignment and performance at high speeds.
