AO= Adjustable Scopes...like them when I hunt wood chucks but at night time for predator hunting you are probably going to miss a few critters because of them....Many times...your going to be calling and the reds, grays, coyotes, coon, and bobcat are going to like your music so well they are going to run right at you...OK 100 yards, 50 yards, 30 yards, 10 yards... OK now try to adjust and get the scope up all at the same time and kill the critter? Make sure when you buy a scope for nighttime hunting make it a non AO type scope...
UM....even deer hunting with them you could miss a buck of a lifetime? Unless you are sitting in thick stuff and have the AO set just where you need it when the deer appears....So I would use it deer hunting in thick stuff...Truly it's not as bad as night time predator hunting but again..Me thinks the AO is for varmints like chucks and crows and such...Could use it in the daytime if your sitting in wide open areas and have a chance to make adjustment prior to shots...Critters like predators...Most times they are moving and this alone makes the AO just not that good of a scope...
