So I just got my EOTECH Tactical HDS, and one of those adjustable bi-level mounts to boot, so it would cowitness correctly. Boy was I excited.


This is the problem. Maybe its just me or something, but from the images that I have seen, on the websites n such, the 2D retcule looks sharp and distinct. When I turn this on (especially at default brightness) the circle and dot look mega "Hairy". I don't know how else to explain it, they look like their made from wool yarn! I have a el cheapo red dot sight that came off of an air pistol with just a dot in the center, and the image quality is the same as the $250 eotech!! It does look better if i peer through the rear sight aperature, but it's still grainy.

Is anybody elses like this? Should I send it back and save up for an aimpoint?! :confused: :cuss:

ShaiVong - the grainy look is a result of using a laser to project a hologram. The EOtech has to project a circle of fine dots because it uses a holographic projector instead of the reflective lens technology found on most red dots. This allows it to have a wider field of view and less peripheal clutter without a dark tinted lens (a la Reflex) as well as a brighter more useful reticle.

It isn't visually appealing; but it doesn't affect operation any. You should check the mount and look for parallax at the extreme left and right of the reticle though since I've seen both of those reported as problems with EOtech.

I like the EOtech and it is a very, very fast sight for close-in shooting; but I like the Aimpoint better for my own uses. Still, I'd try it out before you ditch it.

I had the same problem with mine,you will get adjusted to the fuzz.Now after a few montha of adjustment I love my Eotech.

You'll also want to dial down the brightness to the minimum you need for your lighting conditions. That helps with the "hairiness". It's not a bad system. Give it a chance.

[Jayman]

Yeah, I noted the "hairyness" but still found the EOTECH to be better than any other sighting system I have tried.

I have a hairy sight. Heh.

[ShaiVong]

Talked to an EOTech rep. I think its just my crappy eyesight. I have an astigmatism, which i think is what makes all the dots look streaky. Its MUCH worse without my glasses.

It does look better in higher ambient light.

It's probably spherical abberation, in your eye. Glasses and contacts are usually unable to compensate for this fully, if at all.

I have it too, the red-dot in red-dot sights have a halo of fuzz around them. Street lights at night are a mass of spots, but my brain dosen't "see" them. It just ignores them most of the time. But if I pay attention to the haloes, on the sights or night-driving, it takes awhile for my brain to re-train and ignore them. Until then I'm all :banghead:

The thinner and "pointier" the light source, like a laser dot, the easier it is to produce the halo since the halo is a certain number of degrees away from the light source's percieved edge. You don't see the fuzz on a big flat lit store sign close up because it covers 10-20 degrees of vision, and 1 degree of fuzz is infestimal, but a red-dot covering 1-3 MOA of a degree, 1 degree of fuzz can be maddening.

If you watch the haloes on oncoming car headlights, notice they become "smaller" as the car approaches? They're not though, the halo is still the same size across your field of vision, but the car headlamp is getting bigger. A red dot or holographic sight crosshairs never gets bigger or smaller in your field of view, so the halo seems "stuck".

Spherical abberation also causes color divergence and red seems to spread the furthest to the outside, and blue/violet the least.

The only real fix is to get a newer form of adaptive optic LASIK surgery called VISIX. It uses a computer read reference laser and it measures all optical mis-alignments in your eye, not just the basic focus and astigmatisim like glasses, contacts, and regular "old" LASIK does.

yeah, I have been thinking about this for some time, and I think that it is the only way to fix my funky eyeball problems. Now I just need to find the money :uhoh:

How much is the VISIX treatment going for now?

[hksw]

There is a reason that the EOTech (and other) red dot sights have multiple light intensity settings.

The default brightness when turned on is too bright for normal indoor use, turn it down.

I get the "hairness" only when focusing on the recticle (or still on the front site when cowitnessing), like you do with iron sights. When you focus on the target, like you should with a reddot, the recticle appears sharp and distint. Takes a little while to get used to, since most folks are (and should) be trained to focus on the front site.
