Does anyone looking have one of these units, Lowrance HDS 5 w/Navionics, if so would you share a consumer report about it. I think the price is about $700give or take. Is it user friendly, are the features, Navionics, dual beam, WP saving and so on worth the cost? What kind of transducer do you have and mounte how/where? How is the screen, out in the sun or at night? Any thing else you can share will be greatly appreciated.
