I have a Maxzone. Has cross hairs for 20-50yards. Some guys prefer the red dot style, but I like to have the multiple cross hairs. Same idea as a compound bow sight. As long as you can judge the range to your target, your all set.
I'm now using a TenPoint Pro-View scope on my Phoenix. So far I've shot two does this season since installing it, and it has worked well for me. It has illuminated dots (red or green) at each crosshair that you can shoot with or without being turned on. It's calibrated for a 300 fps arrow, and I've got the 3 crosshairs sighted for 15-25-35 yards.
I have 3 xbows w/ a V-zone on each, do I get 3 votes? lol. I think the V-zone is the very best for an xbow as there is no hold over required. I like being able to take long shots at rabbits or yotes, something I couldn't do as well w/ any other sight.
Varizone. Easy to tune, it allows 5 aim points with exactly 10 yards (or meters if you decrease the ring nut speed) between them. This is very important.

Varizone...On an Exomax I think you could stick a squirrel to a tree at 50 yards with it...Have been tempted to try this but don't want to bust a bolt on the tree.
If I could only have one weapon...it would be an Exomax!
