Like the old saying with rifles.

"Buy the best rifle you can afford & a scope that cost a bit more than you can easy afford."

Same thing with Xbows really, for top shelf performance. You can put a $70 scope on a 2K crossbow & I'll shoot fair......or put a 2K scope on a $400 crossbow & get pretty decent results.

Best of course is about a 3.5K set up that rocks in any & all conditions. But who can afford that.......LOL.......
