I just purchased the Navionics Platinum Plus for California and Oregon. Should arrive by end of next week. I am curious if anyone has any experience using this software. I have a Lowrance HDS-5 which I will be inserting the "chip" into. I have a fishing friend who has this and works great for bottom fishing, no more "fishing" to find good structure. A little concerned that my 5" screen may not be big enough to really utilize the software. Any feedback, tips, lessons learned, from using this software would be greatly appreciated.
