The Humminbird HB2124 CHIRP Radar brings CHIRP pulse compression technology to a compact 21-inch solid-state dome, delivering sharp radar imaging across both close-quarters and extended ranges. Whether you're navigating low-visibility conditions, tracking nearby vessels, monitoring weather, or scanning for bird activity that signals gamefish below, this unit provides the situational awareness needed on the water. It connects via Ethernet to compatible networking HELIX and all ONIX chartplotter models.
