you have to have the dot turned down to the lowest setting when its dark,,,my Dad had one on his Ruger Redhawk for deer hunting,,,he went into his evening stand and set the brightness where he wanted it,,which is the smaller the dot the more you can see the target,,,but he was sitting there and dark was coming and he seen a buck coming in and he put the gun on his knees waiting for the buck to come into his shooting lane,,,well when the buck got in his shooting lane he looked thru the red dot and he couldnt see ANYTHING,,the brightness of the dot blacked out the whole tube,,so he learned from that and always checks it right before dark and sets the dial on the smallest it can be with out turning off
BUT we have never tried one out after dark with a red filtered coon light shining on the target like 6mm06 did
so it might just be the ticket,,,let us know because i am interested in the outcome,,i cant do it my self because my dad sold the gun/red dot right before he passed away so i dont have access to one
Thank you
