I have a decent pair of 10x 42 Nikon binoculars that serve me well. I am looking to purchase something stronger for on a tripod at my house where it is not uncommon to see deer, elk, coyotes, eagles, hawks, etc. I would like to keep the budget around $300, but don't want to be disappointed. A few that I am considering are the Nikon Aculon 10-22x50, Nikon Monarch 5 20x50, Celestron Skymaster 20x80 and Vortex Optics HD 20x56. Any reviews/recommendations would be greatly appreciated.
