50 kHz Sonar frequencies Best depth penetration with lower resolution 83 kHz 200 kHz Low CHIRP Medium CHIRP High CHIRP Wider cone angle provides more bottom coverage and easy lure tracking Highest sensitivity and best target separation in shallow water Provides the best depth penetration with lower resolution images Better depth penetration than High CHIRP with minimal loss of target separation Better resolution in shallow water than Medium CHIRP Custom high Selects a custom single frequency from within High or Low frequency ranges to help reduce/eliminate interCustom medium ference from other CHIRP transducers Ping speed Controls the rate the transducer uses to send sonar waves into the water. Ping speed adjustments can help reduce interference from other transducers. When using fishing modes, ping speed settings are optimized for the selected fishing conditions, so in most cases, adjustments are not necessary. Sonar Operation | HOOK series 22
