Frequency (Change Transducer Frequency)
(Dual-Frequency Transducers only)

A dual-frequency transducer operates with both 200 kHz and 50 kHz.
The 200 kHz frequency has a 12

° cone angle and the 50 kHz frequency

has a 35

° cone angle.

The default frequency is 200 kHz, which is best for use in shallow water
(about 300 feet or less). This frequency is the best choice for about 80
percent of the fresh and salt water sport fishing applications. When you
get into very deep salt water, 300 to 500 feet or deeper, the 50 kHz fre-
quency is the best choice.
