I have never carried them for turkey hunting. You don't need them.
I have a good pair of binoculars in every vehicle which I own, and always carry a pair which is dependent on what I'm hunting. For turkey hunting I carry a pair of lightweight 10x25 Leupold's in my vest and for deer hunting 10x42 Carson's or 10x50's. Over the years, binoculars have been instrumental in killing several good deer and gobblers. Until you become proficient in hunting with binoculars you won't know what your missing. A good pair of binoculars will really help you pick up movement and detail in dark woods by amplifying the available light and allowing you to see into the shadows.
