RE: Bushnell elite "firefly"
I've got one. Mine does not glow for anywhere near to 6 hours. As far as I can tell it glows for less than an hour after exposing it to the light from a flashlight. But that should be plenty long enough for shooting at dusk or dawn. I like it.
I was less impressed, however, with the rainguard coating on the lens. The lens on my 3200 Elite fogs up from my breath just like any other scope I've had. I guess I've got to be more careful not to breathe on the lens when I shoulder my rifles.
