Zoom Range
Zoom Range is used to enlarge some certain depth segment, which is helpful for you to
see small details, fish signals and bottom structure. Your fishfinder has a wonderful
performance to see any depth segment with any scale. For example, if the current Depth
Range is 0~40m, by setting Zoom Range to 20~25m, you can see the sonar image of
the 20~25m depth segment with a 8x scale. And by setting it to 20~30m, you can see
the sonar image of the 20~30m depth segment with a 4x scale.
