I caved and went to a red dot when the bifocals wouldn't focus well enough for the fiber optic sights.
I like batteries in my flashlight and I grudgingly carry a cell phone to appease my wife.
But I generally shun battery powered gadgets for hunting. I don't want to look at life through a viewfinder, I'll keep my memories in my head, not on a computer.
If it has boobies, tires or batteries, sooner or later it's gonna cause you major frustration!
