Ive been shopping around for a while already and finally decided on Orion 4x. I will use it on my Remington to call coyotes in the back yard. I have not made any shot yet but I checked how it performed in the dark night with no moon. With IR on I could detect even small objects from 50 yards. This is enough for me so it is OK I did not buy Gen 2. Though, one day I will probably do it for other needs. By the way, Orion 4x comes with detachable infra red illuminator as included accessory.
