Does this work in areas where there is no cell service? I thought it doesn't but things might have changed by now. I remember some time ago a person wanted to use it off road whether it was fishing or hunting. Somebody mentioned that it does not work in areas of no cell service. Just curious!
On Back Country Navigator you down load maps when you have access to the internet. You can download topo, old B&W or updated aerial, combanation topo and aerial and others. Once you do it for the area you don't need cell or 3-4G service. I run my phone in airplane mode and the GPS will still work.
You can save a screenshot with what ever tracks and waypoints you have added to a map and send it as a text message or print it out. Also, when you make a waypoint you can use the camera on your phone to add a picture to the waypoint. I use this feature a lot to help me remember the spot I marked.
I bought it a few years ago when the app was $1.99. I know it's a few dollors more now. There is a free version also but I'm not sure what you get with that. They update the app regularly and if you sign up they send out a news letter (email) explaining whats new.
I used a Bushnell for a few years and Back Country Navigator does every thing the Bushnell does. Easy to use and cheaper.
