Spend the cash once for quality and you will save yourself thousands over the years. Wish I did that a long time ago. Only brands I can comment on. Nikon Monarchs, 10x40, good glass, weather proof but little bulky if you hike miles a day.They stay in the truck. Swarovski... CL 10x30, best glass Ive ever owned. Light weight, sumbersible water proof (dont ask) all around great binos's. I get eye fatigue with the Nikons, not with the Swaro's.
