Lowrance Mark-5x Pro Operation Manual - Page 16

Sonar Frequency Controls the transducer frequency used by the unit. This unit supports two frequencies: 200kHz and 83kHz. When using fishing modes, ping speed settings are optimized for the selected fishing conditions, so in most cases, adjustments are not necessary. 200 kHz has the highest sensitivity and best target discrimination in shallow water. 83 kHz offers a wider cone angle for more water coverage. The Mark 5X only supports the 200kHz transducer frequency. Sonar Options Accesses sonar display settings and configuration options. Ping Speed (Advanced Mode only) Controls the rate the transducer uses to send sonar waves into the water. Ping speed adjustments can help reduce interference from other transducers. Split Zoom and Split Flasher Switches the sonar display from full screen sonar to a split screen view. Frequency menu Split Zoom 14 Split Flasher
