What i did I turned the SI Sensitivity offset to -7 and the white wave lines went off the screen. If i turn the SI sensitivity offset the opposite way to say 6 or 7 the white wave lines come very close to the central of the screen.
Looks like if I turn SI sensitivity offset to -7 it gos away.
Is that what the SI Sensitivity offset is for ? Because it worked BUT i will see what it really looks like on the water when I go out again.
