Sonar
Custom Range — Upper and Lower Limits
(Advanced Mode only)
Used to select the upper limit and lower limit of
a section of the water column. That allows you to
view a section of the water column that does not
include the water surface.
Upper and lower limits must be at least 6.5 ft (2m)
apart.
Frequency
Controls the transducer frequency used by the
unit. This unit supports two frequencies: 200kHz
and 83kHz.
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 (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.
When using fishing modes, ping speed settings are
optimized for the selected fishing conditions, so in
most cases, adjustments are not necessary.
