First time out hunting pigeons and dove's. Took a bad first turn, shot a few at the 30 yard setting with the mildot reticle, then turned the ABL on to range a pigeon on a power line, the ABL could not range "out of range error message and looping" . Tried everything I could to get out of the loop, turn off reboot, change options "no workie" as this blocked most of sceen/view. Called Utah air guns where I purchased the Crown Continuum and scope, they fixed me up, say ok to the error and quickly distance measer a shorter distance. This clears the loop. Otherwise the scope and ABL worked well with the balistic calculator being on from 20 to 73 yards. For fast action I set a medium range and used experience and the mildot reticle. As near as I can count 200 pests bit the cow poop. Now the scope-does it job but in bright sun can be a pain to see target and reticle "it's a computer screen" but away from sun or darker skies it is acceptable. Now its not in hight end glass class but I can pest with it and for night should be good.
