Garmin AIRMAR 509LHW Thru-Hull Transducer
Description
The Garmin AIRMAR 509LHW is Garmin's best-performing, highest-power thru-hull transducer, delivering 2-3 kW of output across the most popular fishing frequencies: 28, 38, 50, and 200 kHz. Designed for serious offshore and deepwater anglers, it combines CHIRP Low (28-60 kHz) and CHIRP High Wide (150-250 kHz) technologies in a single, streamlined housing for unmatched versatility on the water.
The narrow low-frequency beam is purpose-built for deep water penetration and target separation, while the wide high-frequency beam excels in shallow water conditions - giving you clear, reliable sonar data across a full range of fishing environments. With a maximum depth capability of 6,000 feet and compatibility with a 0-25 degree deadrise range, this transducer is engineered for serious offshore fishing vessels that demand the absolute best in bottom tracking and fish-finding performance.
Key Features
- CHIRP Low (28-60 kHz) and CHIRP High Wide (150-250 kHz): Covers the most popular fishing frequencies in a single all-in-one thru-hull unit.
- 2-3 kW Power Output: Garmin's best-performing, highest-power transducer in its class for deep water penetration and crisp target separation.
- Maximum Depth of 6,000 ft.: Exceptional bottom tracking capability for offshore and deep water applications.
- Dual-Purpose Beam: Low frequency narrow beam (5-9 degrees) for deep water performance; High Wide frequency beam (11x23 degrees) for shallow water performance.
- 25-Degree Constant High Wide Beamwidth: Provides broad sonar coverage when scanning shallower water columns.
- 0-25 Degree Deadrise Compatibility: Fits a wide range of hull configurations for versatile installation across many vessel types.
- 39 ft. Cable Length: Generous cable run accommodates most helm-to-hull routing needs without extensions.

Why You'll Love It
The AIRMAR 509LHW represents the pinnacle of thru-hull sonar performance, trusted by serious anglers and professional captains who simply cannot afford to miss fish or lose bottom contact in demanding offshore conditions. Its dual CHIRP frequency coverage means you are equipped for virtually any fishing scenario - from deep canyon drops to nearshore structure - without swapping transducers or compromising signal quality. The robust 2-3 kW power rating ensures that even at extreme depths, your sonar returns are sharp and detailed. Built to withstand the rigors of saltwater and freshwater fishing alike, this transducer is a long-term investment in on-water performance. Whether you're targeting bluefin tuna in 1,000 feet of water or jigging structure in 50 feet, the 509LHW delivers the crisp, reliable sonar data that serious fishing demands.

FAQ
Which Garmin chartplotters and fish finders are compatible with the AIRMAR 509LHW?
The 509LHW is designed for use with compatible Garmin CHIRP-enabled chartplotters and fish finders. We recommend consulting the Garmin Transducer Selection Guide (available above) or contacting Garmin support with your specific sounder model to confirm compatibility before purchasing. Connection is via bare wire termination, so a compatible black box sounder or a unit with bare wire input is required.
What is the difference between CHIRP Low and CHIRP High Wide?
CHIRP Low (28-60 kHz) uses a narrow beam angle designed for deep water performance - it cuts through the water column with excellent target separation at depth. CHIRP High Wide (150-250 kHz) uses a broader beam angle (11x23 degrees) that is ideal for shallow water performance, providing wider coverage and detailed imaging at shallower depths. Together, they make the 509LHW an all-in-one solution for anglers who fish a wide range of depths and conditions.
What hull deadrise angles is the 509LHW designed for?
The 509LHW supports a deadrise angle range of 0-25 degrees, making it compatible with a broad variety of hull shapes commonly found on offshore fishing vessels, sportfishers, and center consoles. Always consult the included installation instructions and a qualified marine technician to ensure proper alignment and fairing for your specific hull.
Does the 509LHW measure water temperature?
Yes, the AIRMAR 509LHW includes built-in depth and temperature sensing, so you can monitor water temperature in addition to depth readings. It does not include a speed sensor.
Is professional installation required?
Thru-hull transducer installation involves cutting a hole in your boat's hull, which is a permanent modification that requires care and precision. Garmin strongly recommends having the transducer installed by a qualified marine technician. The kit includes installation instructions, but improper installation can cause water intrusion or damage to the vessel. Always follow the instructions carefully and consult a professional if you have any doubts.
