This unit features robust **2 kW Traditional Sonar** with simultaneous **Low-CHIRP (38–75 kHz)** and **Mid-CHIRP (80–130 kHz)** operation. It reaches maximum depths up to **6,000 feet (1,830 meters)**, providing the power to penetrate deep columns (Low-CHIRP) and the precision to distinguish individual targets (Mid-CHIRP). This bare-wire unit is designed for permanent thru-hull installation with a fairing block.\u003c\/p\u003e\n\u003chr style=\"border-top: 2px solid #1D7CAF; margin: 25px 0;\"\u003e\n\u003ch2 style=\"color: #000000; font-size: 1.5em; margin-top: 30px;\"\u003e2 KW POWER FOR DEPTH AND DETAIL\u003c\/h2\u003e\n\u003cp\u003eThe R109LM is a dual-element transducer, balancing the immense depth capabilities of Low-CHIRP with the high-resolution detail of Mid-CHIRP across two optimized beams.\u003c\/p\u003e\n\u003cdiv style=\"margin: 20px 0;\"\u003e\n\u003ch3 style=\"color: #000000; border-left: 3px solid #1D7CAF; padding-left: 10px;\"\u003eKEY SONAR \u0026amp; PERFORMANCE FEATURES\u003c\/h3\u003e\n\u003cul style=\"list-style-type: none; padding-left: 0;\"\u003e\n\u003cli style=\"margin-bottom: 10px; border-bottom: 1px dashed #EEEEEE; padding-bottom: 5px;\"\u003e\n\u003cstrong style=\"color: #333333;\"\u003eExtreme Depth:\u003c\/strong\u003e **2 kW power output** and Low-CHIRP (38–75 kHz) band provide reliable signal return down to **6,000 ft**.\u003c\/li\u003e\n\u003cli style=\"margin-bottom: 10px; border-bottom: 1px dashed #EEEEEE; padding-bottom: 5px;\"\u003e\n\u003cstrong style=\"color: #333333;\"\u003eMid-CHIRP Resolution:\u003c\/strong\u003e The 80–130 kHz band offers superior detail and target separation across wide beamwidths (13°–18°).\u003c\/li\u003e\n\u003cli style=\"margin-bottom: 10px; border-bottom: 1px dashed #EEEEEE; padding-bottom: 5px;\"\u003e\n\u003cstrong style=\"color: #333333;\"\u003eTarget Clarity:\u003c\/strong\u003e Resolution is so precise it's possible to distinguish between individual baitfish, game fish, and underwater structures.\u003c\/li\u003e\n\u003cli style=\"margin-bottom: 10px;\"\u003e\n\u003cstrong style=\"color: #333333;\"\u003eWide Deadrise Support:\u003c\/strong\u003e Supports hull deadrise angles from **0 to 25 degrees** (requires fairing block for correction).\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003ch2 style=\"color: #000000; font-size: 1.5em; margin-top: 30px;\"\u003eCONNECTIVITY AND INTEGRATION\u003c\/h2\u003e\n\u003cp\u003eThe R109LM is a heavy-duty, bare-wire sensor built for high-power, permanent integration into the Garmin Marine Network via a suitable black box.\u003c\/p\u003e\n\u003cul style=\"list-style-type: disc; padding-left: 20px;\"\u003e\n\u003cli\u003e**Bare Wire Connection:** This transducer is supplied with **bare wires** (no connector), requiring expert termination to a compatible **2 kW CHIRP sonar module** (e.g., GSD 26\/28 [1]).\u003c\/li\u003e\n\u003cli\u003e**Housing:** Designed for fiberglass, wood, or metal hulls.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv style=\"margin-top: 30px; padding: 15px; border-left: 5px solid #1D7CAF; background-color: #f0f4f8; color: #333333;\"\u003e\n\u003ch3 style=\"color: #1d7caf; margin-top: 0; font-size: 1.2em;\"\u003eInverell Boating Centre Expert Note:\u003c\/h3\u003e\n\u003cp style=\"margin-bottom: 0;\"\u003eThe AIRMAR R109LM is a professional 2 kW transducer (Traditional CHIRP only) optimized for both deep-water penetration and mid-range target identification.
