i had a tube sight and just recently switched from one..... i always shot with both eyes... it's just something you have to get used to..... if you see double sight then use the one on the left if you shoot right and visa versa if you shoot left.... my groups are a lil tighter and i get "the whole picture" so it's easier to hone in on the target... In all it just takes a lil practice and gettin used to......
