chartplotter / fishfinder questions
I want a combo unit because it''s cheaper to buy the combo unit than to purchas a mapping GPS and a separate sounder. The depth sounders are all in the $200 range. The unit I will prbably buy, the Lowrance M68 S MAP, is $399, and has a color display, detailed maps with navaids, AND a depth sounder.
I figure the fish finder part will come in handy when I want to anchor.
What I don''t understand is why people spend $200 for just a depth finder when you can get a basic fishfinder for $100 or so.
