I have one of the Loggy Transformer safety systems with no instructions. I hope this is not a dumb question, but I am unsure about the correct way to attach it to the tree. How does the "prusik" knot come into play? Does the carabiner go around the tree and then attach to the knot, or does the carabiner go through the prusik and back to attach on the waist belt? BTW: I sent 2 requests for information via their website and never heard back...needless to say, I am underwhelmed by their support. Figured I trust my buds here to help a brother out. Thanks!
