Patman- There are only two advantages of a crossbow over a vertical bow. 1- little practice needed. 2-far easier to understand how to shoot.
You can buy one, sight it in and hit the woods. It shoots no farther or faster than a compound. It is no more accurate. It is one heck of a lot heavier and clumsier. It is ideal for young folks and old folks and ones that are unable to pull a vertical. And.....they can get real expensive.
if I had a choice, I'd still be shooting a compound. I have no choice.
