No thanks. If riser isn't square with centershot it becomes useless. Plus, there will be some riser flex when shot. You don't need a tool to get it close, you can do that by eye by looking down through the cams. On a Hoyt, 13/16 " will get you very close as well. Great place to start tuning. sent from my samsung note 2
That tool was first available in the 80's I think. Not sure if it is still available. I think the laser devices have replaced it.
My sentiments mimic this. Eyeing up center shot is not a difficult task. Any tuning done past your intial setup will take care or centershot issues anyways. Sent from my ADR6350 using Tapatalk 2
x2 I don't think I've ever owned a bow that tuned dead center. Too many variables go into determining what the bow likes for a given arrow combination.
