EOTech's most popular holographic weapons sight, the Model 512 is perfect for people who want the best in close-quarters-combat speed and versatility but don't need night vision. The Model 512 sports a revolutionary sighting system based on advanced holographic technology. The design works by using laser light to illuminate a holographic pattern embedded in the heads-up display window. When the shooter looks through the window, he or she will see a virtual red image of a reticle pattern projected onto the target plane. Overall, the holographic sight improves target acquisition, boosts accuracy, and increases control over the shooting environment.
The Model 512 is built to last, with a rugged aluminum hood assembly and knobbed, tool-free mounting bolt. Other features include a 65 MOA circle reticle with a 1 MOA aiming dot; support for two 1.5-volt AA batteries (lithium or alkaline); unlimited eye relief; and 20 brightness settings. The Model 512 is compatible with 1-inch Picatinny or Weaver rails.

Great sight for the money,

This review is from: EOTech 512.A65/1 Tactical HOLOgraphic AA Batteries Weapon Sight (Sports)
I have used an EOTech 512 for several months now. I am not in the military or law enforcement. I am not an "operator" or whatever the current catchphrase is among the mall-ninja crowd. I am just a casual shooter. That being said, I do expect good performance out of the equipment that I buy. This model did not disappoint. I have found that it is simple to use, and accurate. It holds it's zero through long shooting sessions and banging around out in the boonies. I have yet to replace the batteries in mine, but I also don't leave it on when I am not using it. It has held up to the recoil of 7.62x39 and 6.8 SPC with no problems. I know, they aren't noted for their heavy recoil, but that is all I have used it on. The sight gives me faster target acquisition than an Aimpoint M3. But as others have noted, the battery life is nowhere near that of the Aimpoints. 600-1100 hours versus 5 years. In all truthfullness, that isn't as big of an issue for me. AA batteries are cheap and...Read more

The best and worst,

This review is from: EOTech 512.A65/1 Tactical HOLOgraphic AA Batteries Weapon Sight (Sports)
The HWS is a sweet design, the fact you can use it with a cracked or broken screen is very nice. And while I have yet to see one with a bullet hole through the glass I have used one with mud on it and it worked fine. The open design makes pick up feel very quick. I can make hits with the EOTech faster than with an Aimpoint at close range when using a timer.
All of that said there are some substantial downsides to EOTech's design. The first being battery life, the AA models say they run up 1100 hours with lithium batteries, which is closer to around 800 in my experience. The others have even more reduced run times. All models also have an auto shut off of either 4 or 8 hours. This is easy to circumvent by occasionally hitting the up or down arrow, but something that is a none issue with a modern Aimpoint. Because of the nature of the battery box recoil on certain weapons will sometimes cause the batteries to loose contact and the sight will shut down. My major problem with...Read more

Innovative reticle, uses common batteries, inconsistent quality,
June 1, 2010 Charlie (MI, USA) - See all my reviews
This review is from: EOTech 512.A65/1 Tactical HOLOgraphic AA Batteries Weapon Sight (Sports)
The 512 model (Rev F) is supposed to contain new parts that solve the short battery life issue, however my experience shows that the 512 still has problems with battery longevity. Using alkalines for storage, they will be completely dead within a year even if you don't use the sight. Meanwhile, my wall clocks and remote controls run the same alkalines for 3-5 years without needing a replacement. There is a significant amount of standby current draw with the 512, translation: it saps a LOT of juice even when it is shut off.
The 512 uses a pair of AA batteries, so you can run Lithium, NiMH rechargeable, or alkaline although you will get better life out of the Lithium or NiMH. There are lots of reports about EOTechs with corroding battery terminals, terminal springs that fail, and in my experience I found lots of debris behind the lens. EOTech's customer service is excellent and they replaced the sight without any problems. Some people have a fetish with batteries and will...Read more
