I have a bicycle bag attached to the rear bracket, and when riding over bumps, holes on the trails I noticed, actually heard, the bag and the binos banging around. I have the Steiner Peregrine XPs and even though they are built tough, and in a padded case, should I place them objective lens down, lying flat to the back, lying flat on the focus knb, or with the ocular facing down. I would hate to find out later that I had placed them incorrectly.
