Move the camera guy five feet higher or lower.
I still firmly believe that a compound bow that was not intentionally engineered to be used with any device will not perform to it's full capabilities.
The engineers at Hoyt, Bowtech, Mathews, G5, Bear, PSE, and so on were provided a set of specifications and requirements, and they engineered their compound bows to meet or exceed those requirements. When you take any piece of technology outside of their specified functionality, you are just asking for problems.
If you can afford $5000 cameras, you can afford multiple stands, crossbows, or whatever else you need to do your thing, and remain within the parameters of which the equipment was designed for. A DrawLoc may work, but if you ever spoke to the guy who actually designed that bow, I'll bet he'd just shake his head. They weren't considering that in all of those computer models and simulations that will occur before actually making those components. They were assuming a human being would draw and hold the bow.
A closed mind keeps the truth out
