  1. Yes, this is a re-upload. I got married this past weekend and i didn't have time to produce something new, so instead we decided to fix this review up so that it's monetized.

    Yes I care about making money short and long term because I run a school house first and foremost and up until fairly recently YouTube videos have been a huge expense that cut away from my bottom line.

    No, I don't care if you have a problem with that and you can get bent if your anti capitalism nonsense insists that you voice that problem.

    Yes, the words thermal and night vision specifically are the reason why the first upload got demonetized.

    Also during the premier of this video, YouTube AI saw me manipulating my brn4 during a talking head section. During live streams you're not permitted to do so.

    And a video premier counts technically as a live stream complete with live chat, so the AI misinterpreted this and took down my video without giving me access to it.

    To deal with this I appealed that video because overturning the take down makes the AI treat you nicer in the future if you win rather than just deleting it, fixed that section and sent this video out in the intrest of time and staying on schedule…. it was monetized instantly….

    Yes all if this is stupid and annoying.

    No, I'm not going to go to another video distribution site because the audiences there are both incredibly small and even more idiotic than commenters on this site that swear that shit equipment is great because they don't shoot enough understand what real data looks like.

    Also, again, I'm not going to another video sharing site because i run a school first and foremost, greatest exposure possibility means more eyes see me and that means more people in classes…..

    Private or open enrollment…..

    YouTube while far less necessary to my overall success, gets me the most eyes by an enormous margin…. so no…. I'm not going to your favorite little jank ass site that's overrun by flat earth truthers.

    Lastly, and this is for the vast majority of you. Thank you guys so much for the kind words and support. I had a lot of class alumni that have been training with me for almost a decade at my wedding and it's been a great week in general.

    Take care y'all.

  2. After the passing of The Great Paul we lost a good no nonsense non McDonald's tier non gunbro guntuber and I appreciate it.

    I don't mind having fun and being entertaining but you get tired of the Disney tier quips of trying to be funny every 3 seconds.

    That being said, I'm glad you're here brother. A perfect balance of information and enough to keep the ADHD crowd entertained.

  6. The EoTech is the most beautiful optic I've ever looked through. It's 100x better and faster than using a red dot. Every time I pull out my AR with the EoTech on, it reminds me of how superior it is.

    The only huge con is the need to turn it on before use. I wish they'd just design an Auto-on feature, it would solve the problem. For home defense you have to remember to turn it on before going to sleep, if you're on patrol – turn it on before your shift. So then you have to add that into your routine on top of the battery dying. IT just sucks we can't have our cake and eat it.

  9. Wearing arrowheads 5” trainers while watching. 1 year now. Love it. I slip my leather kore belt in the loops and carry. Can even get away with no belt and tying. Expensive and polyester but reccomended

  13. I’m glad this video exists. I read the same sources, had the same responses to the criticisms, and had the same experiences with the Eotech, and so I came to the same conclusion as you.

    And I think it’s important that more people understand this optic and how good it really is

  15. Brother, I don't even know what parallax is, and I don't have NVGs. But I do have a slight astigmatism. So etched reticle prism optics and flashlights for me! I'm not poor anymore, but I still have a poor man's mentality. So paying $800ish for an optic is something I might pay for a 4x ACOG, but not an EOTech. My buddy has one, and I just don't care for it. Though I admit it works well with his magnifier.

    Commenting nonsense for the algorithm. Good luck man, and congrats on marriage.

  17. I would really like to see how this compares to a Romeo 9T. It's honestly the closest thing that can compare to this optic, overall. There was a guy on ARFCOM that was talking about using a graphene 16350 battery and having an aftermarket shroud made for the reticle that makes sense for something like this where you get the battery life you need but it has all the advantages of the Eo-Tech. Lasers have also become so more efficient that I definitely thing EoTech will come out with something in the next couple of years that will perform better than a holosun. I think the weight is a non-issue. Once again, the biggest downside is the battery life.

  20. Eotech and L3 separated after the US mil sued them for selling bogus optics. Eotech/L3 knew of the issues as far back as 2006 and continued selling defective optics to military and law enforcement personnel, a shitbag move from a shitbag company. They offered a "fix" in 2013 that didn't fix anything. In 2015 the FBI did their own testing and determined that Eotech optics still sucked balls. One specific result, at 122'F the zero shifts and never returns.

    The thermal drift has not been corrected.

    The moisture incursion has not been corrected.

    Delamination has not been corrected.

    Eotech lists the parallax as 4moa +/- an additional 3moa, for a total of up to 14moa across the optic. They also admit that at "extremes" of -40 or 122'f you can experience another 4 moa. So worst case, you grab your rifle from your hot car/trunk and your shots can be 11 moa(11 inches) off the mark at 100 yards. And left edge to right edge deviation can be 18moa…

    Parasitic battery drain has not be corrected.

    battery life is shit
    They're twice the weight of a T1 with mount
    Inferior water submersion rating

    The reticle is grossly over hyped. If you're reasonable competent with the 65MOA reticle or any optic, you can and will find a simple dot. Seeing as you should be looking at the TARGET and not the reticle, your mechanics with mounting the rifle and reps doing so are what make the difference, not the reticle design.

    An Eotech does nothing better (and many things worse) than an Aimpoint. All from a shitbag company who put profit ahead of user safety and product performance. If LARPing as an SF go fast ninjaSEALcommandoDeltaAssassin is your goal, buy one. If you have critical thinking skills, live in reality, and have integrity, buy something else.

  26. More minutia: The dot size not expanding under magnification is one of the things that can only be accomplished with a hologram, it's literally physically impossible to do it by any other method:

    That single dot isn't just not actually 1 MOA, it's not even .1 MOA. That teeny tiny area of space the light from the dot occupies is 10 microns wide.

    Why are you able to see something that small? It's due to the intense luminance of a laser. That quality can be exploited to emulate the focal character of a true point source of light. The physiological reason you can perceive anything that small at all is the same reason you are able to see stars with your naked eye. Oh God we have to talk about biology.

    Essentially, what happens is due to constant microscopic eyeball movement that the brain suppresses from being perceived by the self (Microsaccades), a tiny point source of light may pass over the fovea in the eye extremely fast over and over in such a fashion that multiple eye neurons are firing at nearly the exact same time which allows the eye to discern something actually is there, as if it's taking multiple samples of the same image. This is why the extreme luminance is crucial. The brain is both unable to derive a true size for the object or render the true size of it to the self even if it could perceive it because it is already below the human eye's minimal angular resolution which is why the eye movements are needed to accomplish it. The brain essentially goes:

    "Fuck it! I'm making the dot this size, it's the best I can do! I hate myself!"

    That is a generalization of the physiology involved, there is a hell of lot more going on in the eye and brain, the point was just to provide a useful perspective.

    It isn't that the eye can or cannot see it is there or not, it can certainly actually take in the visual information establishing something is there. It's just that dot size is the smallest contrast the brain will render for the conscious self to discern in it's attempt to define the scene before it with the visual information it received from the eye. God that sounds convoluted, I really am trying hard to make this digestable. At any rate, the dot is going to appear to be the size of the particular viewing eye's current minimum angular resolution at the time it is looking at it, most of the time that happens to be about 1/60th of 1° of an arcminute, which coincidentally is approximately 1 MOA. That can fluctuate depending on things like pupil dilation in different lighting conditions, impaired vision and such. It can get kind of confusing since we are trying to describe a discrete fixed width of something with figures that were intended for measuring angles and deviation.

    The reticle was created during the recording of the hologram by passing the collimated object beam through a reticle mask before interfering through the reference beam. At the center of the mask was a 10 micron wide hole. Because of how microscopically perfect a properly recorded hologram is, during playback the 10 micron wide center dot of the precollimated wavefront is reproduced with that same actual size. It actually will reproduce the wavefront of the reticle already collimated too because it was already collimated when it was recorded. It isn't that all holograms inherently produce collimated light, it's just that the reconstruction is so perfect if the recorded subject itself was collimated light than that quality of the wavefront will be preserved for playback.

    The center dot is for all practical purposes focused at infinity. Even if it was not already collimated, the only possible rate of divergence after passing through a hole so small is so narrow by the time it reaches the recording medium it ultimately will have had no effect for us and it will still be far too small for the brain to render it as anything smaller then it already does. The same is not true of the outer ring of the reticle though again they are pre-collimated when recorded with extremely low divergence as well. Only the dot is that small.

    Within the EOtech sight there is a "collimating reflector." However, this is not here to cause the reticle to be collimated since it is not necessary. Illuminating the reticle hologram from a pretty broad range of angles with the correct wavelength laser will always reconstruct the reticle already collimated regardless of the illuminating sources divergence or lack of divergence. The actual reason the beam is collimated within the optical train is to ensure the entire reticle hologram is illuminated so there are not spots where the reticle abruptly disappears for the user while also doing so without lighting up the interior of the sight. It also prevents spots of the the reticle appearing FAR brighter than other parts. The Vortex UH-1 uses a very different optical train, so much of this actually doesn't apply to it. The center dot perceived size stuff does though.

  27. I have astigmatism, especially in my right eye, which sucks as a right. Got an exps3-4 and a vortex uhg that are really nice, but both are very blurry to me. LEDs like my promethazine lp1 work better for me

  37. The Eotech is a pre recorded hologram, & they discovered at a particular time of day a slight shift was noticed, it ended up being a train near by that caused vibration, so they spent a shit load of money making a "train proof" special structure with essentially suspension system to combat that.. pretty cool

  39. Great review. I’ve ran an Eotech for years. My solution to having to possibly turn the optic on under stress is to run fixed back up irons that are 1/3 cowitnessed. So if it’s not on, I can shift to my irons with a half inch shift of my head.

  44. This is by far the best review on the internet.

    I’ll add my 2 cents. I lived in the mountains at the end of a road on acreage for years. We had chickens.

    I would often (every few months) wake up suddenly in the middle of the night, grab my rifle, and run outside to protect the chickens from coyotes, badgers, foxes, etc…

    So I had real world “Grab the rifle with the Eotech and try to finger the on button while half awake” experiences. SEVERAL times I had no reticle. The buttons are mushy and easy to not press all the way. I also ran a fixed front sight (as mentioned here).

    I switched to Aimpoint/Holosun always on RDS for this rifle role. Just as described in this review for others who grab and go.

    If you are using a rifle for “bumps in the night” you should consider having an always on red dot and backup sights. One less thing to worry about.

    I love the Eotech. Under Nods it is unparalleled. Fast acquisition, minimal parallax for awkward positions and magnified shooting. As said, this is the best “offensive” optic on the planet.

  47. I believe the reason Aimpoint achieved such impressive battery life is custom LEDs that are specifically sized for their optics making them much smaller and effecieng than standard LEDs. Another manufacturer buying off the shelf LEDs would have much worse battery life.
