If you're working canyons, seamounts, or deep channels where a standard transducer leaves you guessing, this is your tool.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProduct Summary:\u003c\/strong\u003e The R109C-LH is a thru-hull CHIRP transducer that delivers 117 kHz of total bandwidth from a single installation — covering everything from 38 kHz low-frequency work to 210 kHz high-frequency detail in one shot. You get 5 to 10 times more bottom detail and fish separation than conventional transducers, with depth capability to 10,000 feet. That means you'll spot individual baitfish, distinguish game fish from structure, and navigate deep water with confidence.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCHIRP Low Frequency (38–75 kHz)\u003c\/strong\u003e — sweeps across a full 38 kHz bandwidth at low frequencies — gives you superior depth penetration and bottom detection to 10,000 feet, ideal for deep offshore work.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCHIRP High Frequency (130–210 kHz)\u003c\/strong\u003e — sweeps across 80 kHz of high-frequency bandwidth — produces razor-sharp target separation so you distinguish between baitfish, game fish, and structure with precision.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e117 kHz Total Bandwidth From One Transducer\u003c\/strong\u003e — eliminates the need for multiple installations and multiple transducers — saves you money, installation time, and hull penetrations while giving you frequency flexibility your electronics demand.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdaptive Beamwidth\u003c\/strong\u003e — narrows from 19° to 10° at low frequency and 8° to 4° at high frequency — tighter beams mean sharper target definition and cleaner bottom signatures as you scan deeper or shallower water.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFast-Response Temperature Sensor\u003c\/strong\u003e — tracks water temperature in real time alongside depth data — helps you identify thermoclines and seasonal patterns without a separate sensor installation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUrethane Housing with High-Performance Fairing\u003c\/strong\u003e — engineered for thru-hull durability and minimal water flow resistance — ensures signal quality and reduces turbulence noise on boats running at speed.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecs \u0026amp; What's Included\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eCompatibility:\u003c\/strong\u003e This is a thru-hull transducer compatible with Airmar-ready fish finder heads and systems.
