What "problems" are you talking about?

I did notice one thing with the Guardian that freaked me out. While I was shooting one day the first shot made some metal on metal noise. It sounded as if the cam had broke or something. As you can imagine I was very worried. Upon further inspection I noticed the bolts on the limb attachment were loose. A couple of quick turns and it was all back to normal. Now before I shoot I always make certian I check them out. They haven't come loose since, but I check it just to verify.
