The Humminbird ICE Transducer with Dual Spectrum CHIRP Sonar is built to reveal subtle differences between fish, lure, and nearby structure across a versatile 130–250 kHz band. Choose a 15° beam for maximum detail in tight ice holes, or switch to a 21° beam to widen your sonar sweep when you need more coverage. This transducer pairs cleanly with compatible HELIX CHIRP units in Ice Fishing mode, making setup straightforward for winter outings.\u003c\/p\u003e\u003ch3\u003eTwo beams, one purpose\u003c\/h3\u003e\u003cp\u003eThe Dual Spectrum CHIRP system delivers precise returns with target separation down to three-quarters of an inch. That level of detail helps you distinguish a decisive bite from lure movement, even in cluttered water or at depth. You can interpret the sonar quickly to decide when to drop or raise your jig, based on what you see below the ice.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e130–250 kHz frequency range supports flexible ice fishing performance\u003c\/li\u003e\n\u003cli\u003e15° beam for maximum detail; 21° beam for broader coverage\u003c\/li\u003e\n\u003cli\u003eTarget separation down to 0.75 in for clearer readings\u003c\/li\u003e\n\u003cli\u003eDesigned for HELIX CHIRP units in Ice Fishing mode, with exceptions for specific HELIX 12 CHIRP GPS models\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCompatibility and setup\u003c\/h3\u003e\u003cp\u003eDesigned to work with all HELIX CHIRP units in Ice Fishing mode, this transducer integrates into your winter gear with minimal fuss.
