In the market for a new fish finder. Have $400 to $600 to spend. I will use it in Fresh water no deeper then 200FT. We use downriggers and would like to see the wieghts on screen, I like the color ones but I can live without. My old "new" humingbird shows fish in the garage, but I can't find them. Thats a little "Fishy". Would like to see bait fish like Cisco's in Fort Peck Res. in Montana. I see some Lowrance, Bottom Line, Raymarine, Si-tex and Furno on ebay. Its all overwelming. What do you suggest?
