Custom range menu NOTE: When using a custom range, you may not receive any digital depth readings, or you may receive incorrect depth information. 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. Frequency Controls the transducer frequency used by the unit. This unit supports three conventional sonar frequencies: 50kHz, 83kHz and 200kHz. 200 kHz has the highest sensitivity and best target discrimination in shallow water. 83 kHz offers a wider cone angle for more water coverage. 19 Sonar Operation | Elite-7

Frequency
Controls the transducer frequency
used by the unit. This unit supports
three conventional sonar frequencies:
50kHz,
83kHz and 200kHz.
200 kHz has the highest sensitivity and best target
discrimination in shallow water. 83 kHz offers a
wider cone angle for more water coverage.
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.
NOTE
:
When using a custom range, you
may not receive any digital depth read-
ings, or you may receive incorrect depth
information.
