From SIG SAUER . . .

SIG SAUER Electro-Optics is pleased to introduce the ECHO3 Thermal Reflex Sight.  The ECHO3 is a direct view thermal sight, utilizing SIG SAUER BDX technology, with the capability to capture images and record video in eight different color palettes.

“The ECHO3 is an ultra-compact, lightweight direct-view thermal sight,” said Andy York, President, SIG SAUER Electro-Optics. “The innovative direct-view thermal display on the ECHO3 is a massive improvement over traditional eyepiece style thermals which induce eye fatigue and force the shooter to look through the sight.  The ECHO3 allows the shooter to sit back and view the thermal display and when targets are identified, the new BDX reticle technology allows for exact aiming solutions in real time.”

The SIG SAUER Electro-Optics ECHO3 is a compact thermal reflex style sight available in a 1-6x or 2-12x magnification, equipped with Ballistic Data Xchange (BDX 2.0), the ECHO3 can be used with 9 different onboard SmartBDC™ ballistic holdover reticles or it can be paired with any KILOBDX rangefinder. The ECHO3 features a motion activated MOTAC™ display that powers up when it senses motion with over 6 hours of continuous runtime, and offers video and image recording in eight color palettes, and six brightness settings. The ECHO3 Includes a quick disconnect mount, with an easy to adjust zoom lens with throw lever attachment.

    If only I had been born rich instead of so damn good looking.

    1. avatar John Boch says:

      My problem is that I’m smart as a horse and hung like Einstein.

      And that’s about a factor of ten outside of what I cannot afford. Well, I could afford the sight, but not the divorce that would follow.


      1. avatar Craig in IA says:

        Well, look at it this way: I just got a new gun for my wife. Pretty good trade considering her age…

      2. avatar StLPro2A says:

        In the long run, the divorce is an inexpensive investment in your future. It was that one last beer you bought before asking her to marry you that was expensive. Too soon old; too late smart.

    2. avatar Dave Huff says:

      The wife is buying me one of these for Christmas!

      1. avatar Country Boy says:

        well , you should be a real sport & tell her to buy us all one while she’s at it…….ROFL

  2. avatar Chief Arc Paid Wal Mart Shill says:

    Whatever. I can get the same quality optic at Wal Mart with an air soft optic with a bic lighter dick taped to it, all for about $29.95.

    1. avatar dph says:

      Dick tape? Sounds painful, but to each his own.

      1. avatar Felix says:

        It’s 18 1/2 minutes long.

        1. avatar Waylon says:

          That’s what I’ve read. Dick Tape is also supposed to be one of those “fire and forget” type of deals.

  3. avatar TP says:

    Was extremely excited reading the info just to have my hopes destroyed when I got to the MSRP.

    1. avatar Phil LA says:

      Yeah same here. Gotta say that the Dick Tape sounds more appealing.

      1. avatar Ron says:

        I too, like many here would like to know more about this Dick Tape. Primary uses, costs, best bargain ect…

  4. avatar Asdf says:

    320×240 for 3k+? There are better thermals out there.

  5. avatar bob says:

    Like reading the review of a Patriot Missile.

    I mean, I’m sold, but…..

  6. avatar Anymouse says:

    BDX seems kind of wasted if you don’t have an accompanying thermal range finder. You’d see your target in the sight but wouldn’t be able to see it in the range finder to calculate the drop. Does this mean one is in the works?

  7. avatar Excedrine says:

    $4K is actually on the “cheap” side for a thermal optic, relatively speaking, especially for a unit that’s comparatively small and lightweight. But with 320×240 resolution, I’ll pass.

  8. avatar rudukai13 says:

    The 1-6x range combined with infinite eye relief is something I’ve been waiting on for a long time. You’re looking at a screen anyway, there’s absolutely no reason we should be limited to the same narrow eye box problems associated with traditional glass scopes. This one might not be it, but low-power, variable-magnification, day/night thermal fusion scopes with unlimited eye relief are the future for hunting and combat optics systems. I’d just like to see more development of them on the tactical/combat side of things like the new Steiner CQT

  9. avatar Matt in Oklahoma says:

    If only the wife didn’t want heat and food this would be possible

  10. avatar former water walker says:

    Well that’s pretty nifty…

  11. avatar Cash Money says:

    Sig thermals suck. I have a trijicon reapIR, flir RS32 and the sig. while not in the same price ranges the sig is crap.

    Do yourself a favor and buy a trijicon or a pulsar and stay above 5k for best results.

    1. avatar neiowa says:

      Well aren’t we just the trust fund snowflake. Does mom make you come upstairs for meals?

  12. avatar David Bradford says:

    I’ve managed (so far) to be sensible and not toss my money away gambling on the lottery. After seeing the MSRP on this, I may have been provoked enough to do something stupid with the little money I do have. I want one!!!!

    1. avatar Ron says:

      I play the lottery occasionally… while the odds are astronomical, if the multiple universe theory is true, in some universe somewhere, I struck it big. You’re welcome rich me.

      1. avatar strych9 says:

        In the multiverse theory you win even if you don’t buy a ticket in this version of reality because in some other universes you do buy the ticket and in some of those you win.

        So that advertisement they run “You can’t win if you don’t play” is technically untrue… at least in some other universe…. if the multiverse theory is correct.

        1. avatar Dan in Detroit says:

          You may be technically correct, assuming that some version of you has bought a ticket and won. However, “No you can win if some you doesn’t play.” is not an easy tag line, would require too much background to understand, and be too open to erroneous interpretations.

  13. avatar D.J.U. says:

    Ok! Its small, compact along with a magnification factor. Image resolution really should be far better for the price. Not that I’m an expert, but electronics in this field are makeing a big leap, as I’m counting the 4k camera and screen image technology in this group. ( yea I know those things are not thermal), but at this price point the could have at least brought it up to at least a 720p level for visualization output.
    Still for the size, it’s still remarkable and I’m sure just the starting edge of being more compact. The real question is “will it take a licking and beating and still keep on ticking”.
    And for that price point will the warranty be able to hold up to real time.

  14. avatar Phil LA says:

    $3200? Who buys this stuff? I know the military but they aren’t shopping at Midway.

  15. avatar Echo5Bravo says:

    Ok. I’m confused. Doe this come WITH Dick Tape? Or is that some kinda option I have to get from Sig or Midway? If it does come with Dick Tape, whats the cost? (plus shipping and handling) What exactly are the tactical applications for/with Dick Tape? Are there any advantages or disadvantages vis-a-vis the thermal image when using Dick Tape? Is Dick Tape a NFA item? ie: destructive device, AOW, or some kind of barrel enhancement system.

    1. avatar Waylon says:

      I think if this comes with the Dick Tape it would be worth the cost. My cousins friend who uses Dick Tape on the regular says it turned his life around.

  16. avatar possum says:

    Do they make a mount for a HiPoint

  17. avatar Dude says:

    Save some of that development money for QA QC guys.

  18. avatar Libertarian says:

    If you want good (for an thermal cam) resulution white enough fps

    but still 4000 dollar arround in the 25 fps pro version

  19. avatar Ian says:

    What is with all the worthless clickbait ads on sites like this which should be the prime locations for quality content? It’s super low brow and makes you look fly by night shady.

  20. avatar Will Drider says:

    I bought the Echo 1 about to years ago. Worth every penny at $1300 street price. The only drawback with it is that it will illuminate the “shooters face” whereas an eyepiece with rubber booty doesn’t. I’m not sure if the same occures with the “Direct view” but an illuminated screen has to emit light.
