I'm looking at buying a new Magnetospeed chronograph and I was wondering if they can be used on other hunting/shooting equipment? Has anyone ever used one for a crossbow, shotgun or handgun? I have seen how they are supposed to mount on the rifle barrel, but could one possible mount it to a tri-pod (something?) and shoot over and close enough for the machine to read? I would like to have one, but just don't want to spend that kind of money just for rifles only. Thank you in advance with any helpful advice.
