SKU: AIRM265CLM21HB
MPN: M265C-LM-21HB
The Airmar M265C-LM-21HB 1kw Low Medium CHIRP transducer with Humminbird 21-pin cable delivers depth-only sonar performance built for anglers and boaters who demand reliable structure detection at mid-range and deeper water columns. This in-hull transducer integrates seamlessly with Humminbird fishfinders, eliminating the need for through-hull drilling and offering a cleaner installation path for both new builds and retrofits. Whether you're chasing walleye over structure, mapping basin transitions, or verifying bottom composition in lakes and reservoirs, this transducer bridges the gap between entry-level performance and professional-grade sonar clarity.
Operating at 1 kilowatt of continuous output power, the M265C-LM-21HB combines dual-frequency CHIRP technology across a low-frequency band (42–65 kHz) and medium-frequency band (85 kHz) to maximize bottom definition and target separation from shallow flats through deep open water. The low-frequency component penetrates thermoclines and suspended structure with authority, while the medium frequency sharpens resolution on hard targets—submerged timber, rock piles, and laydown wood become unmistakable on screen. CHIRP modulation spreads energy across a frequency range rather than a single pulse, reducing noise and improving signal-to-noise ratio in weedy or turbid conditions where standard narrowband sonar falls short.
The pre-assembled Humminbird 21-pin cable eliminates guesswork during installation and pairs directly with Humminbird units equipped with that connector standard, saving setup time and reducing wiring errors. At 15.2 lbs, the transducer is robust enough for tournament use yet compact enough for smaller center consoles and bay boats where weight and space are critical. This solution excels for anglers prioritizing depth capability and structural detail without the cost or installation complexity of through-hull transducers, making it ideal for rental boats, seasonal platforms, or anyone seeking plug-and-play sonar confidence.
