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.\n\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003cdiv class=\"custom-product-faq\"\u003e\n\u003cdetails\u003e\n\u003csummary\u003e\u003cstrong\u003eProduct Specifications\u003c\/strong\u003e\u003c\/summary\u003e\n\u003ctable border=\"1\"\u003e\n\u003ctbody\u003e\n  \u003ctr\u003e\n\u003cth\u003eTransducer Frequency\u003c\/th\u003e\n\u003ctd\u003eCHIRP Low (28-60 kHz) and CHIRP High Wide (150-250 kHz)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eTransducer Power\u003c\/th\u003e\n\u003ctd\u003e2-3 kW\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eBeamwidth - Low\u003c\/th\u003e\n\u003ctd\u003e5-9 degrees\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eBeamwidth - High Wide\u003c\/th\u003e\n\u003ctd\u003e11 x 23 degrees (constant 25 degrees)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eMaximum Depth\u003c\/th\u003e\n\u003ctd\u003e6,000 ft.\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eCable Length\u003c\/th\u003e\n\u003ctd\u003e39 ft.\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eDepth\/Speed\/Temperature\u003c\/th\u003e\n\u003ctd\u003eDepth and Temperature\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eConnector Type\u003c\/th\u003e\n\u003ctd\u003eBare Wires\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eSupported Deadrise\/Transom Angles\u003c\/th\u003e\n\u003ctd\u003e0-25 degrees\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eMount Type\u003c\/th\u003e\n\u003ctd\u003eThru-Hull\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003ePart Number\u003c\/th\u003e\n\u003ctd\u003e010-12187-20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/details\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFAQ\u003c\/h2\u003e\n\u003cdiv class=\"custom-product-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWhich Garmin chartplotters and fish finders are compatible with the AIRMAR 509LHW?\u003c\/summary\u003e\n    \u003cp class=\"faq-content\"\u003eThe 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.\u003c\/p\u003e\n  \u003c\/details\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWhat is the difference between CHIRP Low and CHIRP High Wide?\u003c\/summary\u003e\n    \u003cp class=\"faq-content\"\u003eCHIRP 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.\u003c\/p\u003e\n  \u003c\/details\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWhat hull deadrise angles is the 509LHW designed for?\u003c\/summary\u003e\n    \u003cp class=\"faq-content\"\u003eThe 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.
