Point '4. Humminbird Options' describes that RM needs to be able to determine the speed of sound in water in order to locate track-points correctly within the Humminbird sonar view.
Does this option only applies for the sonar view or also for the calculated depths?
Is it usefull to select this option when using a Lowrance unit?
Thanks,
Sam
