Those are some good pictures! I recieved my Leafriver DC-1BU yesterday and the hand viewer. Cabellas has sent me a bag which has been opened and the Strap is missing, but Leafriver is sending me a Strap and aInstructional Video. The video Cabellas sent had been used and it's scratched bad. Waiting to set it up!
