i guess each to his own mike . all the gadgets sure compicate live. you might think of putting on a wind gauge maybe radar. then you wouldn`t acually have to see the animal. that would be to old school.
just a quick note, most clubs in the okanagan allow /encourage xbows at their 3d shoots. you shoot in your own class, no rangefinders allowed. this evens the playing field and means anyone can have fun. not all clubs have ribbons or prizes. just a day with people of like interest playing outdoors.
