I'm looking for another portable fish finder to take up to the Boundary Waters with me this year, anybody use one they would recommend?

For the past 2 years I've used the little wrist watch deal, in a word, they ****. They might work for pond fishing but in lakes the size and depth of Herrington, they have little application other than a depth finder. Plus they crap out after a few days because of the iron in the water up there.

The one I am looking at is the Eagle Cuda 168 Portable Fish Finder. Anybody else use this one? I've got a Cuda on my boat and it works OK for the money. I also looked at the Fishing Buddy, anybody use that one? I like the portablility of the Cuda over the Buddy plus the less obtrusive mounting bracket which will be helpful for 2 guys in a canoe with multiple rods, paddles, ect.

Any help is appreciated. Thanks, Ted
