I received my Argos yesterday while I was out boating. Despite a tiring day in the sun I swapped out the Helix for it and went out for a quick sight in. Two shots at 10 yards to make sure I was on paper, then a few more at 25 to zero it in. I zero at 25 since most of my shooting is between 15 and 35 yards. The first thing I noticed is the eye box on the Argos is more forgiving, eye relief was about the same between the two scopes, maybe 1/4 inch difference. What surprised me was how much clearer and crisper the Argo glass was. A much brighter view and very crisp. I'm not saying the Helix was bad, in fact I thought it was pretty good until I looked through the Argos.
This is my first FFP scope but it doesn't really matter since I usually aim for the eyes or right between the eyes on rabbits and squirrels so use 18 or 24x the vast majority of the time.
I'm glad I took the time sighting it in because early evening, about 15 minutes after I finished, my neighbor invited me and the wife over for a holiday drink and to exterminate the squirrels attacking his bird feeders and seat cushions. Within minutes I took out four that were between 25 and 35 yards out, All dropped in their tracks with head shots,
