Worth it

I recently went out into the Inter Coastal Waterway on my jet ski not aware of how shallow the water is. I needed an app that would give detailed depth and this is fantastic. I like the tracking on it and the measuring tool. Very easy to read and clear with bright colors. The only way I could turn off the GPS when I was not using the app was by going to Settings to turn it off. Can you add a button to turn off the GPS so I do not use up my battery? Otherwise, this is well worth the new price.
