HB2124 CHIRP RadarCompatible with select networking HELIX models and ONIX, Humminbird CHIRP Radar features CHIRP pulse compression, setting a new standard for compact solid state radar. It delivers superior RADAR imaging on both long and extremely short ranges. This translates to better situational awareness in low-visibility conditions and helps identify birds and floating obstacles for clues to where gamefish are located. You can also track weather and vessels with amazing definiton.
