Prime Day on Amazon has seen a bunch of these on sale for increasingly appealing prices. Lemme ask y'all a couple quick questions: 1. "Golf" vs "hunting' rangefinders--is there really a difference? Are any of you hunting with a golf rangefinder? Does it work ok? 2. Has anyone tried one of these $70-80 jobs? Gogogo, Anyork, etc? Is it really worth it to plunk down $1-200 more for a Vortex or some such?
