i spent $50 on a used Eagle fish ID pro... which did the job with finding depth and learning how to use a FF.. but i cant wait to upgrade to something better.
the $100-$150 range is nice for a humminbird or a cuda, and it'll teach you alot about how to read what structure, fish, and bottom look like... but you'll be wanting to upgrade it asap after you realize that it isnt as good as you want.
