Broadhead tuning?

how do you spin test em without one of those rotater things? do you just put the tip of the BH on a table or somethin and spin it?

 

Yea. I just spin them on something. It is so obvious when something isn't straight.

 

Spin test your broadhead on the palm of your hand, A Thunderhead is a hard broadhead to tune, there are too many options on broadheads . I shoot a 100 gr.Muzzy and T-3 ,broadheads, they shoot the same, I do shoot about 100 times a week during off season and about 150-200 times a week during hunting season, I would practice alot ,before trying to adjust anything, go to a pro shop let them check your set up, everything has to be right when shooting a fixed head where as a mechanical you can get away with alot.
