Bottom discrimination provides detailed information about knowing the make-up of the seabed, categorizing it into four different categories; “Rocks”, “Gravel”, “Sand” and “Mud”. The make-up of the seabed can be tremendously helpful information when looking for fishing grounds, as well as for finding good anchoring spots.
Bottom composition can be displayed in one of two modes:
The standard graphic display mode shows the most probable bottom composition by graphic or four colours
The probability display mode shows the most probable bottom composition in graph form
Bottom Discrimination is available on:
