I know there are a few posts like this, but I am looking for a spotter that is fairly light weight for backpack hunts. I don't really know what power or diameter I need, but I will be using it in central South Dakota and Western Kansas for the most parts but will use it in my future Elk and deer hunts further out west. I have some good 10x binos but need a good score to go with them.i don't want to spend anything over 600 or so and would like to be around 500 if possible. Any suggestions?
