So I went to the range today and pulled out my favorite AR and turned on the EOTech as usual and noticed the reticle was VERY dim... couldn't see it outside. Switched out the batteries with the spare lithium AA batteries and had the same issue. So, I get home and turn it on...and it works. However, it seems like the default brightness setting is more dim, although it can go fairly bright now. And, although the glass is perfect, there is a ring around the reticle where it dims. I took pics as I have no other way to describe it. Each pic is on the outside around it and you can see where it is dim. I will contact them on Monday, but has anyone ever experienced anything like this?

| Are you sure it is a genuine EO-Tech? They issued a warning a couple of years ago about counterfit sights from some country that starts with a "C". A hologram doesn't carry any charge whatsoever, and shouldn't need to be recharged. If I remember correctly, they have had some issues with the glass and the holographic film. I'd just give them a call and see what they say. |
| They have tremendous customer service. They will take care of you. I had a really old one finally have an issue like that and they paid shipping both ways and repaired it free, and got it done really , really fast. When it came back it look like they replaced it with a new one, but it was the same one. They did a great job fixing it and cleaning it up too. |

Non the less he did state that this should be done every 6 years to keep them dependable. In fact they seemed to be very vague with any details about what actually caused the dimming. |

Unfortunately, it is barely 2 years old. As such, I am very disappointed but will see what they say. At this rate, I am getting an average cost of almost $250 a year. And yes, it is absolutely a real EOTech purchased new. They're going to give you a new one. The have great CS. They will ask you to ship it to them, you will get a bran new replacement. Those dim spots are not normal, especially considering the location of the circle/dot |

Edit to say, IF, I need to be thinking about sending my EXPS back to Eotech every 6 years for a nitrogen "refilling", mine will be on the exchange shortly. As much as these things cost, it is beyond dumb if the darn thing need what I would consider to be critical service.
I will explore another Aimpoint or even just irons if this is the case. |

They'll fix it, like they fixed mine, but the fix is worse than original dimming.

Not exactly like that but i have seen them dim out. Eotechs lose their "charge" in the holographic lens. They need to be recharged every 6 years or so according to the Eotech rep that deals with my agency. Huh? Charge what? Isn't it just a low powered laser diode? Maybe some dirt is obstructing that area of the image. |

There have actually been a few reports of people whose reticule began dimming when viewed in certain portions of the the sight. I have started noticing it in my OPMOD EOTech. Mine exhibits dimming in the lower section of the sight, and in a narrow band in the middle of the left-third of the sight.
EOTechs are purged with an inert gas - it isn't bad information being passed. One reason that was given for reticule dimming is the nitrogen leaking from the sight. EOTech CS has confirmed that leaks do often result in lower overall brightness, although I don't know that it is the same reason that brightness might be spotty. I think that might be what Brutus2 is thinking of. They have to re-purge the device, and reseal it. I can see how one might say that they are "recharging" the nitrogen in the unit. I am getting ready to contact EOTech and see what they can do for me. Some people have reported getting their sight repaired for free, while others have indicated that they were charged for the service. I was going to just live with it, since it is minor at this point, but my sight is also exhibiting a weak detent on the elevation adjustment. So, off it will go. |

This is exactly what I was referring to. I didn't access to the email Eotech sent to my agency so I couldn't go into detail. Thanks for the clarification. |

I know that you are just trying to pass down what you believed was credible information, but it is false. There is no way no how, any degrading material that is installed or included in any Eotech product. Can you imagine if there was an optic produced that "ran out of gas" after so long? I realize that a Trijicon optic may need a tritium replacement after so long (they still work to aim with though), but so long as an Eotech has good batteries, they should be good to go. Quoted:

EOTech Optics, with fading holographic display (brightness) issues. The range staff contacted EOTech Company and were told by a customer representative that the gas inside the holographic display needed to be recharged. The representative also stated that this something that would need to be done every 5 to 6 years during the life of the optic. The optics manufactured in 2008 are still under warranty, therefore the service is covered. However, optic models from 2007 and older are no longer under warranty and would be charged $79.00 for any needed maintenance and to refill the holographic display with the required gas for the continued operation of the optic. The main concern is the potential for failure with the display during use by xxxxxxs in the field This is part of the email concerning dim Eotechs , I'm not saying that it is the cause, but the manufacturer thinks it is. |
Brutus2, as mad as I am to say it (because I can't believe something so "battle built" could be so weak), you might be correct after all. I do NOT want to be sending an optic back to the factory to be refilled by nitrogen because of some cheap seal gives way. If that's the way it is, I will go back to irons.

I would be angry if I had an Eotech. I made the initial inquiry here about 2 months ago because I had not heard of the problem . There is something to it after all but it may not be the cause of all the reticle problems. My motive never was to be right or wrong, was more intel gathering for safety purpose |

I've got a 14(or so) year old 512 that is still going strong. never had to send it in for any purge or work. The reticle is bright and no fade towards the border of the window what so ever.
I did have them send me a upgrade fix kit for the battery compartment about 4 yrs ago. It still worked but the battery spring came out with the battery. They did offer me a RMA if I didn't fell comfortable installing the new kit. But, I did it myself with no problem. Other than that I have been VERY happy with it and will never sell it. I have had it on: Colt 6920 (current) Colt SP1 SBR 556 Rem 870 12ga Springfield M1A MSAR STG556 F/A Colt SP1 conversion SKS paratrooper I trust this sight with my life! |
| I think it is just one of those things that, for whatever reason, only shows up on certain units. I know a lot of people, including people with dept. issued sights, who have never had an issue of any sort with their EOTech. Mine is on a range gun that has been tuned for minimal recoil. I don't bump it around in a car all day, or use it in crazy weather. Yet, I still ran into an issue. Just my luck! I would hope that if it were truly widespread, they would come up with a better solution than "send it in as needed". I don't think mine is more than three years old - certainly newer than five years. |

Nitrogen purge is leaking. Unfortunately the downside of EOtechs. I've had to send 2 553's in to get recharged. Free of charge. Some guys have to pay, not sure what my case was. Possibly because the 553 is their higher end model.. I don't know.
Only took about a week to get it back. If it's not under warranty just fill out another one on their website. It's what they told me to do anyway. 
I love eotech but this issue has me leaning more towards an aimpoint. Can't beat that battery life. ...or an ACOG..fuk batteries! |
