The maps are pricey but well worth the money the detail is incredible I found trails I didn't know existed. My Garmin has different profiles I use marine in my boat most lakes have depth profile lines good when going to an unfamiliar lake.
My first GPS showed blips with bread crumb trails now I can see my location on a Topo map easy to see the surrounding terrain.
