Hi FEENIX,
I've just bought the same model. I've never owned a GPS. I've always relied on a compass & maps. I get the concept of how a GPS unit works. But there are so many functions on the Oregon 560T, that I doubt if I'd use 25% of them.
There have been more than a few times in Wyoming, Utah, and Colorado where I became navagation-challenged: politically correct BS for lost. When such conditions arose, I sat down, drink water, get out my compass, and think. However, I can see the wisdom of having a GPS show me how to get my butt unlost.
I'll be hunting a different area of the same buck deer unit of Utah this year. While I'll still rely upon my compass for navigation, I am going to use my new GPS to precisely mark waypoints of where I'll hope to see HUGE bucks.
I bought a new SUV last year. The woman who sold it to me asked me about a navigation system. I told her that I can look at a map and figure out how to get to a location. Or I'll use my iPhone's iMaps. She smiled and told me that she didn't have a navigation system in her pickup. She used her iPhone.
