As a wideband CHIRP transducer it covers a broad frequency range rather than a single fixed frequency, giving sharper target separation and clearer bottom/fish detail than a traditional single-frequency transducer at the same power. This class of transducer is aimed at larger sportfishing and offshore boats that need serious sonar penetration and resolution at genuine depth and range - external mount with a fairing is the standard installation method for boats with moderate-to-steep hull deadrise where a flat transom or thru-hull mount wouldn't sit level. It's designed to pair with a compatible Garmin sonar module or CHIRP-capable chartplotter/black-box rather than working as a standalone unit. A fixed beam angle across its supported frequency range keeps sonar coverage consistent whether the unit is operating at its lower or higher CHIRP frequency band, avoiding the inconsistent coverage footprint that can come from a transducer whose beam shifts significantly between bands - a genuinely useful trait for a transducer expected to be switched between frequency ranges depending on target depth and species.
