ultra dot makes one too now
http://www.ultradotusa.com/ultradot_dist_blue_009.htmwhat you described is one of the things I am nervous about on the "auto sensing" units and what is pushing me towards the Ultradot with the 30mm tube. Having the ability to fine tune what I need for given light conditions. I am thinking more and more that the autosensing reflex are perhaps better suited to IPSC style shooting (and may get one for my 1911) where me and the target are likely in the same lighting.. now hunting, I may be in a blind, the deer/hog under a tree in shadows, whatever...
and the abiliy to dial in exactly what I want is appealing
leaning very heavily towards the matchdot with the 2, 4, 6 and 8 MOA dots
still pretty compact, more so than an aimpoint and more so than a scope...
and by all accounts, they stand up to heavy recoil fine
I am also thinking about using a leupold one piece base with the lowest turn in rings I can possibly get to keep it nice and tight
