I have a tall outdoorsman bino adapter. Bought the tall thinking I'd eventually get some bigger glass (15x56 binos) that would necessitate the talls. Instead, I went with a spotter so I don't foresee getting bigger binos. Not looking to sell and take a loss only to have to buy a short adapter. The tall works, just a little big and bulky for my needs. Willing to trade straight up if anyone is looking to go from a short to tall adapter.
