When using a dual frequency transducer, you can select a frequency for the
echo 150 Sonar screen when using a dual frequency transducer.
NOTE: The echo 100 operates only at 200 kHz.
You can show data from a 200 kHz sonar signal or data from a 77 kHz sonar
signal. The 200 kHz frequency shows better detail, has a narrower beam, and
is typically used in shallower waters. The 77 kHz frequency penetrates deep
water more effectively and has a wider beam, so it can be used to cover a
larger area.
1. From the Sonar screen, select MENU > Setup > Sonar > Frequency.
2. Select a frequency.
