I've had the first of two Ares ETRs on a 40XB 22RF w/Krieger bbl for a week or so of shooting from 50yds out to 200. I was very impressed with the optical quality, the turrets have very distinct clicks, and I like the 'brown' finish, which is close enough to burnt bronze CeraKote that it shouldn't be hard to get a set of rings painted to match the scope's finish. After shooting the ETR on the 22RF, I moved it over to a 7-08 Improved 30* custom and did a fair amount of shooting with it on steel from 600yds. I really had no complaints, aside from the floating dot being a bit too small to suit my tastes. It'll not be distinct or maybe even visible in the 10x-12x range where I'd have the scope set for movers, although the open center of the reticle makes a good aiming point in that magnification range. The dot was fine while I was zeroing the scope on paper, but I'd noticed it being harder to see while shooting on the 22RF on steel at 50yds after a few hits had chipped a bit of white paint off the surface. But when shooting the 7-08 at 600, the dot was easier to see, as long as I had the scope up to 16x or higher. A couple of things to keep in mind here - 1. I've never looked through a Kahles with the SKMR3 reticle; would like to know how the size of its floating dot compares to the ETR's. 2. I'm going to be 67yrs old in a few days - my vision sure as heck isn't what it was 30yrs ago.
Overall, I'm pretty impressed with the ETR. Would I prefer it to another Cronus? No, I think the Cronus is a bit easier to get behind, and I still prefer the more distinct aiming point the crosshair presents, especially on the pre-BTR Cronus reticle, where it is VERY distinct, yet not so heavy as to cover up any of the small targets I've shot in 22RF precision rifle matches. I've shot a couple of 22RF PR matches with a new Cronus BTR, and even though its reticle is much finer than that of the pre-BTR, I still had no problems seeing the aiming point, regardless of the background. I did notice while shooting the oldest Cronus I have on a Bighorn TL2-SA Dasher on the same day that I had the 7-08/ETR out, it seemed that the ETR's glass was a tad bit brighter than that of the Cronus. Barely noticeable, and I'm not at all certain that I'd have the same impression on another dark overcast day like that one. But I've been hoping for the chance to compare the three Athlon scopes - Cronus BTR, pre-BTR Cronus, Ares ETR - to each other, as well as to a Gen III Kahles K624i, all in the same rather dark lighting conditions. Might get the chance later today - if it doesn't rain again.
