kinda new to the whole holo sights thing, and just wondering what the big difference was between the different eotech models.

i know some are water resistant, night vision capable, etc., but as far as the lower 510/511/512 models vs. the 550's, is there a difference????

just checking out prices on stealbay for a used sight, but confused because of the different 511s and 12s that im seeing that i cant seem to find any information about on eotech's website.

tried the search function here too, but came up with nothing.

please inform me, and enlighten a newb to holo sights. thanks

510s are good to 10 feet

511 = No night vision compatability, uses N battery, 4 inches
512 = No night vision compatability, uses AA battery, 5 inches

550s are good to 33 feet

551=NV compatible, uses N battery 4 inches
552=NV compatible, uses AA battery, 5 inches

Hope that helps

510, 511, 512 etc... last digit = difference is in battery-type...

51x vs 55x... difference is that 51x is not-NV (night-vision) compatible.... 55x is.... they got a NV button, which ultra-dim the reticle.... so you only be able to see the reticle thru a NV-scope (theoretically)

5xx.__ ... after the dot means the different reticle type.... a65 = 1MOA center dot + a 65MOA ring

they now have many different reticles... including some with BDC(bullet-drop-compensator)

recticle, night vision compatability, water proofing.

I have a 551 that is night vision compatable for $300. I only used it for less than 10 hours. Let me know.

on the 510 series watch out, theres reticles for less than lethal weapons and one with a single red dot, double check to make sure you are getting the reticle you are lookin for,

here is my eotech with the standard reticle for example

The reticle in the picture is ".a65"

"reticles for less than lethal weapons and one with a single red dot" <- those are ".d1"

So, know what you are ordering when you are ordering one. Some of the newer reticles are VERY VERY cool...

".AR223"

".XR308" for .308
http://www.swfa.com/images/eotech_xr308_popup.jpg

".XR500" for .50 BMG
http://www.swfa.com/images/eotech_xr500_popup.jpg

There are quite a couple more that is in their catalog, yet I couldn't find them online.

Personally, I can understand the usefulness of the AR223 0-300, 400, 500, 600 reticle.... but I can never imagine using an EOTech on a .308 to engage a 1.2k meter target(why 6, 9, 1.2k)... nor an EOTech on a 50cal to engage a 2k meter target(1k, 1.5k, 2k)....

sounds good, leaning towards a 511, but wondering if theres a difference with the ones with the "old" buttons or new ones.

thanks for all the quick responses.

New buttons (557s) are on the side, old buttons are in the back... so you can still easily manipulate them if you have a magnifier flipped down.

Your eyes are playing tricks with your brain. When using the EOTech, don't focus your eye on the reticle, focus on the target, then the reticle will becomes "clear" and "crisp".

That's funny. I just bought a 512 and when i turned it on it was just one fuzzy red dot. At first I thought it was defective, but then I found out why on EoTech's online troubleshooting guide. It stated that if you are nearsighted you will require your corrrective lenses in order to see the reticle correctly. Threw on one contact and what do you know, reticle as clear as day.

:oops:

I've been reading that even a 511 or 512 is fine with NV as the brightness adjustment is plenty to get it dim enough to use it with NVG.

Anyone personally tried this?

You do need the NV model to dim down enough.
The dimmest settings on non-NV bloom out looking through night vision.

I think bullet drop reticle for 308 and 50 BMGs were meant to be mounted in 1919 or M2HB's.

It would make sense that way.
