I have read quite a bit about this and quite honestly, there's a lot of
info out there. I plan to fish offshore - 40% , inshore - 55% and some
lake - 5%. I live in central Florida. I would like something that
looks below the boat as well as range outside of the boat.

The boat is 18' 6" CC. I would like something fairly inexpensive, and
of good quality. I don't need tons of bells and whistles, however, it
will be on this boat for at least 3-5 years.

TIA!
