Sharper detail under the ice

Ice fishing demands clarity in a compact space. 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.

Two beams, one purpose

The 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.

  • 130–250 kHz frequency range supports flexible ice fishing performance
  • 15° beam for maximum detail; 21° beam for broader coverage
  • Target separation down to 0.75 in for clearer readings
  • Designed for HELIX CHIRP units in Ice Fishing mode, with exceptions for specific HELIX 12 CHIRP GPS models

Compatibility and setup

Designed to work with all HELIX CHIRP units in Ice Fishing mode, this transducer integrates into your winter gear with minimal fuss. It ships with an 8‑foot cable and a float to help position the transducer properly in the ice hole, so you can focus on the bite and the jig action.

  • Includes 8‑foot cable and float for proper ice hole positioning
  • Ready to pair with compatible HELIX CHIRP ice fishing units
  • Rugged build optimized for cold environments

Real-world use

In a quiet winter morning, you lower the line and watch clear, separate returns appear as you scan the hole. You can switch between beams to gauge depth and structure, and to evaluate the relation between your lure and nearby targets. The Dual Spectrum CHIRP setup offers possibilities for more informed jigging and lure presentation without promising specific results.
