Attaching back pack straps to Summit Viper
I bought a Summit Viper SD climbing tree stand. As far as I'm concerned the instructions are terrible. Had a friend look at it yesterday and we could not figure out how to attach the backpack straps. The shoulder straps have buckles on the straps that hang down but the single strap where they join is a sewn closed loop is there a part missing. Any help would be appreciated. The umbilical strap was not in the box and I phoned Summit and they are shipping one right away. Just wish they had better parts diagram for each model.
Thank you Michael
