Auto vs Manual Range for fish details?

Hi

Is Manual Range/Shift functionality better to find fish details compared to Auto Range (including with bottom zoom)? Why? What is the technology behind that?

Thak you Daniel
 
Mazzuca,
Thank you for your inquiry.
Neither function is "better" as they both can be useful at different times and under different scenario's..

The manual range / shift functionality would allow you to zero in on one particular area of the water column (possibly where the target fish species are suspended off the bottom at a particular depth).
In auto range the sounder attempts to always depict the sea floor as the bottom depth changes. The bottom zoom is useful for closer inspection of the bottom & fish species that tend to stay close to the seafloor. For bottom fish you might find white line function helpful as well. This depicts the strongest signal (usually the bottom = burnt red color) as white so as to help separate it from other targets close to the bottom.
