When your boat is at the bottom of a 30 feet + water crest.
the radar waves reflect back and you have no idea what is on the other side
of the crest?
You can monitor a blitz on you screen and all of a sudden it disappears as
your boat is going down the crest. Avoiding collision with floating debris
require more than a technique and electronic.

True, when the waves are not higher that your radar's random antenna.
