GW, I finally took the Montana 600 hunting last Friday and used it to mark some range monitoring sites today.
It's pretty easy to use, even for a tech ignorant cowhand.
The landowner chip is uber.
I'm not sure about the Oregon but if it is chip compatible(and cheaper) I would get that.
The Montana was on sale last winter otherwise I might have bought something else. Think it was $350 or 400.
