EOTech makes holographic weapon sights, the company that invented the technology and remains its defining name. Founded in 1995 in Michigan and grown out of the Environmental Research Institute of Michigan's work in holography and heads-up displays, EOTech (short for Electro Optics) solved the engineering problems that made a holographic firearm sight practical and introduced the first one at the 1996 SHOT Show. Its sights were later adopted by U.S. special operations and the Marine Corps for close-quarters use, cementing a reputation built on a genuinely different approach to aiming.

The lineup centers on holographic weapon sights like the EXPS and XPS series, paired with magnifiers for reaching past close range, along with the brand's VUDU line of magnified riflescopes. EOTech also produces night vision and laser aiming products for professional users.

What sets a holographic sight apart is how the reticle is formed. Rather than reflecting an LED off a lens like a red dot, a holographic sight reconstructs a laser-lit hologram of the reticle within the window, which keeps the aiming point true even if the window is partially obstructed or cracked, and allows more complex reticles like EOTech's ring-and-dot pattern. That reticle supports fast target acquisition up close while the center dot serves precision at distance, and pairing a sight with a flip-to-side magnifier extends its useful range. The trade is battery life and cost against a red dot, which is why buyers weigh the holographic advantages against their needs.

Pair a sight with a weapon light for low-light capability, mount the rifle with a sling, and compare red dot options across the optics category.
