Must have

I bought this app a few weeks before a charter in St Pete. I was able to browse around the area and gain a comfort level from 500
Miles away. During the charter my phone spent a majority of the time sitting on top of the screen of the nice color chart plotter that was mounted on the boat. I found my phone was easier to read, much more responsive, and the screen was only a tiny bit smaller.
One added perk, I was posting pictures of my trip on Facebook in real time. With this being on my iPhone I was able to take screenshots of the app so I could show friends where we were and how fast we were going with just a couple of clicks.
Over all, very cool!
