can anyone give me an opinion of this unit. i live in northwest louisiana and i need to make sure that the local lakes i fish are included on this unit. is there anyway i can check tomake sure before i take the plunge. i checked the Under Construction website and couldn't find a list of lakes covered. i don't think this unit is compatible with a "chip" so if it is not on the internal memory of this unit, i am not gonna pull the trigger.

any help will be appreciated. i got some bass pro gift cards that are dying to be spent.
