I am in the decission process of a hand held GPS and was concidering the Montana 650T. I hunt a lot and make trails on my property. Even I can get somewhat lost out in the tamarac swamp. I would like to make a map of my property with the trails and save. I see that the unit comes with a 100k topo loaded. I hear people talking about 24k maps that are better. Why would this be??? I am new to this hand held technology
