Well the benifit is if you buy a combo tag is it is good for bow or gun, you can usethe first one for a doe and the second for a buck if you are bow hunting or if you are only bowhunting you can use both for does only. gun you have to use the first as a any buck tag and the second as a 4 on one side or better. If you just purchase a bow tag you will only get one tag and then buy a gun tag you will only get one tag!! I hope that helps.. Walt
