I run Navionics Platinum+ chip in my gps and it is a great peace of mind in an unfamiliar area. Don't for get to update your chart card as a TON of updates are put out everyday. I am constantly reporting and logging my sonar charts in hopes of not only helping me but improving my maps and helping others out through updates. Also, I just got a new card, the nav+ regions. It comes pre loaded with all the navigational charts and sonar charts (1ft contours fishing charts). No computer geek tech needed. Easy! I just thought I would throw that out there. Very affordable card as well, which is key when you are me and need to save as much $ as possible to make the wife happy.
