Gentlemen,
A lot of stressing over the wrong beam angle! The horizontal beam angle may be 4degrees, but the vertical beam width is probably around 25 degrees. What that means is the radar has a narrow beam with for separating channel markers or pilings on the water. The 25 degree beam angle will not separate a boat from a UFO if they're on the same relative bearing and ones on the surface and one is hovering at 100 feet. The 1 degree down angle at rest is fine. It will give best performance compromise between cruising to the fishing grounds and keeping a watchful eye out while checking the sounder for structure. Just my.02, BuzzCutt
