Most aren't aware of the huge parallax advantage since EOTech does not publish competitive data. Being a DOD contractor they tend to operate differently but if you look at which optics are awarded to the tip of the spear door kickers, there is a lot of the reason. If you look at local agencies, they are more often than not, divided. Patrol rifles usually get Aimpoint/MRO but SWAT wants EOTech. Notice the pattern.All reasonable... But you just don't see them at the highest levels of competition often. Wonder why that is?
And I do think a lot of people are turned off by the size/weight and the fact that the holographic laser requires much more power to run. Many that shoot comps also use it as a defense weapon and there is certainly something to be said for being able to leave your optic on for 5 years in that case instead of worrying about every ounce of speed and parallax mitigation. Plus a better three gun optic would be a LPVO because of the distances.
I have/had about every kind of optic and all of them have their strengths for different scenarios but if speed is the number one priority it will always be EOTech. (unless something proves faster)
If you want to check the big delta in parallax compared to a red dot, mount a EOTech behind or in front of a red dot on your rail and run one of the optics reticle to meet the other. Aim at a spot on a close wall and move your head back and forth. The difference will be clear. They exhibit less parallax across a window that is significantly larger, it's quite a feat. There is a technological advantage that a holographic sight has in this particular regard.
