Does anybody have any first hand experience using an Centra Collimator Spy.
Im looking to add additional vertical adjustment to my Centra Duplex Vario as Ive been having some issues with my sight image and after alot of trial and error and thanks to you guys (https://targettalk.org/viewtopic.php?t=65562) I have finally found that my issue can be resolved with an Centra Collimator Spy.
Just wanted to see first if there worth while before I place an order.
Thanks.
