I've been following this thread and watching for an actual GPS recommendation based on what others use. Last year I used the Navionics App on my iPad and it worked well. I wanted to add a fixed mount GPS to supplement the iPad. I heard some new units provide dock to dock routing and some from other lake users (Not on Winni) were touting LakeVue. And before 30 people reccomend a paper map, I have and use my trusty Bizer... lol
