Excellent advice already given. Power is your primary consideration... my Humminbird is 8000 watts and resolves things very well, several orders of magnitude better than my old crappy Eagle.
I went with a different model Humminbird that has 5 different transducer "beams" shooting out in a fan under the boat. Because of this, its able to detect fish within a specific beam and show it properly in relation ship to the boat, as well as idenify the depth under each beam, and draw it out in true 3d. It works well and I'm happy with it, the downside though is that when stationary you are only reading a "slice" of the water column below you. Its fine for trolling though. A larger single beam cone will show you any fish within a radius below the boat.
I also like GPS capabilities and use them alot more than I first thought I would.
