Intro to EOTech: How Holographic Sights Actually Work (Ad-free) (Patreon)

Holograms are pretty close to space magic, but today I will try to explain how they work in an understandable way. They have also proven surprisingly difficult to find commercial use for, but one program at the University of Michigan Ann Arbor led to the creation of EOTech to produce holographic weapon sights. So once we (hopefully) have a better understanding of how these sights work, we will look at how they differ from red dot sights, and why their specific pros and cons are.

I don't like it is soooo complicated but between a reddot and an eotech... holographic with typical 2 AA bats. something like an acss would be nice though.

The way I see holographic sights is simple. Theoretically they have genuine advantages over red dots and some time in the future may become universally better, but for the time being KISS wins out.

Well, anyone w/ serious astigmatism is going to choose the EOTech over any RDS.

Over 20 years ago when I bought my first AR, I put a EOTech on it and loved the sight. About 3 years later the sight seemed to not be as bright as it was when new. Then I found out the US government had taken EOTech to court over this issue and EOTech was now taking back the sight and would refund your purchase. I was happy that EOTech was taking back the sight but concerned that they never contacted me about the issue considering the high cost of the sight. Because of that concern I took my refund and bought a Sig red dot an 4x magnifier, which I still have and like.
