Buy the delux version with the vertical and horizontal adjustment marks. I had mine tuned in 6 shots. Easiest to tune and most reliable hunting rest on the market. After tuning mine properly I purposely shot the same arrow 150 times with absolutely no damage whatsoever to a Blazer vaned arrow. If you are worried about losing 1-3 fps because of this style rest then take off your string silencers and replace them with an STS and you will be actually faster with this setup.
