Lowrance Elite-7 CHIRP Operation Manual - Page 23

Only frequencies supported by your transducer will appear on the Frequency menu. 50 kHz Sonar Frequencies Best depth penetration with lower resolution 83 kHz Wider cone angle provides more bottom coverage 200 kHz Highest sensitivity and best target separation in shallow water Low CHIRP Provides the best depth penetration with lower resolution images Better depth penetration Medium CHIRP than High CHIRP with minimal loss of target separation High CHIRP Better resolution in shallow water than Medium CHIRP 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 | Elite-5 & Elite-7 20
