I understand the concept of "run what you brung", but unfortunately think it must be limited and controlled. Example: if a traditional shooter brought his bow straight from hunting in the woods to compete your argument says he should be allowed to compete. But what if he had hash marks up the bow which he could use in the woods to aid him at different ranges? Should he be allowed the implimentation of a system not approved of in the rules of competition? I don't really see it as any different as the bino's. I simply can not see how you can allow the possibility of 1 range finding devise and not others. The ability to see the target better is not problematic for anyone, but the ability to rangefind is. I don't see how you get past that.
