Cliff, I have both and now are older middle of the road models, Humminbird (9yrs old, triple beam) fixed too the boat and the Eagle (14yrs, single beam) is rigged as a portable. They both do what each model is supposed to with the only draw back on the Humminbird is with the transduser having a flat bottom sometimes at top speed I lose the bottom depth, may be on the new models the transduser has changed. Hope this helps...
