I think that is an excellent introductory video. His delivery was flawless, crisp clear voice and he clearly understood this crossbow.
The 70 -100 yard range dots get progressively off to where at 80 yards, the crossbow is shooting over 5” high if properly sighted in for 20-60. So, his high hits @ 70 were not his fault.
When he shoots various broadheads, he’ll likely be in shock. The only differences will be slight vertical impact differences due to incurred drag when spinning more surface area of some BHs causes a lityle more drop.
