That statement is some bullcrap. It has a significant advantage over a bow (trad or compound), and anyone who is not being a fanboy will acknowledge that. At least be honest when you argue for the inclusion of crossbows.
Yeah - they are louder, heavier and clumsy - hugh advantages.
Also hear they position themselves on that fixed platform automaticaly with no movement and the deer always come in and pose at that exact spot.
The disadvantages are enough so I have no interest in one personaly, but support the right of all to use them.
