While writing a review on the new 788ci HD DI combo by Humminbird, I found two images on the box that make absolutely no sense to me whatsoever.
Has Humminbird revolutionized the sound wave and it's properties as we know it?
In this image it appears as if the sound wave shoots out to the side (along. the surface of the water), then at a certain point it appears to take a 65 degree bend heading for the seabed.
In this image it appears as if DI has two beams, one straight down, and then another that runs out to the left, right AND down, like a curtain??
