Believe it or not, I use one of those metal pear shaped shower curtain hangers.
I needed something in which to safely secure my binos and at the same time use one hand in order to pick up and put back my binos while holding my bow. Luckily, my belt has holes in it so I could attach the hanger securley so it doesn't move and fall off. It works great and it's cheap!!
The chest harness is good too. It all depends on your preference.
