I use the see-thru caps on all my scopes as I have a terrible time with anything that isn't fastened... however, my loss is your gain and if you are up in the high-country of Colorado and find one of the many bikinis I have lost up there -- you are WELCOME!

Anyway, they work for me and are better for quick target acquisition than anything else I have found.
