5.5.1 Frequency (kHz)
The Sonic 2024/2022 operates on a user selectable frequency, from 200 kHz to 400 kHz, in 10 kHz
steps. The operating frequency can be changed on the fly; there is no need to stop recording data,
go offline, or load any firmware. The operating frequency is selected via the drop down menu next
to Frequency (kHz).

The optional UHR upgrade enables the sonar to operate at 700 kHz for Ultra High Resolution. If this
option is installed, there will be the added 700 kHz frequency, after 400, in the available frequency
list. If the upgrade is not installed there will be no listing of this frequency.
