I used to have an Eagle on my old humber that came with the boat when i bought it - i replaced it with a garmin plotter/sounder as i didnt have enough room for seperates - to be honest as far as fishfinding and bottom tracking went the eagle was a much better unit.
you can get the
Eagle Fish Easy 2 from
JGTech for £129 inc VAT and inc Delivery
Whatever you buy though - make sure you get one intended for salt water - some of the cheaper units only have low power transducers intended for lakes which will not work so well in salt water.
