Sonar Operation This unit supports two types of sonar: Conventional and DownScan. The features described in this section are for conventional sonar. Refer to the DownScan operation section for information on DownScan features. CHIRP A CHIRP (Compressed High Intensity Radar Pulse) transducer transmits a modulated pulse of all frequencies within the bandwidth of the selected transducer type. This results in better image quality, better target separation and greater depth penetration. This unit supports High CHIRP, Medium CHIRP and Low CHIRP, depending on the transducer. CHIRP can be used with Lowrance conventional sonar transducers. • 50/200 kHz (Low/High CHIRP) • 83/200 kHz (Medium/High CHIRP) To use CHIRP, select the desired CHIRP frequency from the Frequency menu.
