Frank:
I tried to check the factory draw length on the Cam and 1/2 as I stated. I then realized that this was impossible since the tag and box is marked with a draw length range.
I did go back to do some more testing on the Spiral Cam and 1/2. First, the 29" specified draw length measures 29 3/4" when pulled hard against the wall (which is the way this bow should be shot). When pulling until the draw stop just touches the cable (I use a drawing machine to get very precise), I got 29 5/8" (1/8" less).
The bow cam set at the #1 post setting. I moved the post to the #4 setting and it was then 3/8" shorter and had less let-off. You won't get 1/2" as you mentioned because you are starting at a number and moving 3 spaces (1/8" for each space makes 3/8"
. I did check the let-off at it's highest setting and could only get 61% effective (not AMO) at the factory setting (which was the highest). The Cam and 1/2 did get the advertised 75% let-off; but, it was also effective and not AMO. Most companies bend this rule so I don't find it offensive. My equipment for doing this test is probably not as sophisticated as that which they have at the factory. If you plugged a 5% error possibility factor into these let-off numbers, they would be close - but they're not AMO!
And one thing I want to make perfectly clear, all this is typical data for 98% of the bow companies in the market today, including the other top players out there. You have to also keep in mind that I'm testing 'production' equipment. Hoyt is just using the best data they can obtain to meet the advertising ploy that has become a standard of the general market by Ad Execs over the past 10 years.
