SIG’s ECHO1 and ECHO1 B Thermal Reflex Sights What’s the Difference?

SIG has really been shaking up the optics scene lately with its line of SIG ECHO1, Romeo, Tango and Whiskey optics.  These are serious optics and the ECHO1 and ECHO1 B Thermal Reflex Sights are no exception.

With the introduction of the ECHO1 and now the ECHO1 B, we felt it might be helpful to lay out some of the features and explain the difference between the two models.

First, lets clarify the difference between the two:

The ECHO1 is the full meal deal and and comes with the Romeo1 micro reflex optic mounting hardware! It also comes with a protective cover and the data cable.

So why would you want the data cable? Well we will go into that below……

The ECHO1 B is the same thermal optic but it doesn’t come with the protective cover, data cable and the Romeo1 mounting base.  It does come with the standard notch sight though for when things get up close and personal.  You better practice your hold over a lot though because otherwise we would literally pay money to watch that go down lol.

Think headline “Angry wild pig takes out man in MAGA hat“.

So, which one should you buy?  Well we personally think you should buy the ECHO1 and here is why…..

  1.  As a friend mentioned recently, walking around with a thermal sight on your weapon is not going to provide the full picture!  Night vision intensifiers and regular glass optics rely on light reflecting off surfaces to paint the picture.  Thermal is a digital reflection of temperatures and if that coffee table is the same temperature as the floor then you are going to hit the coffee table.  Same with the hot wheels on the wood floor.   So what does this have to do with the SIG ECHO1 and ECHO1 B? Well as we stated above you can piggy back a SIG ROMEO1 on the SIG ECHO1, thus giving yourself a very viable red dot alternative to the thermal solution.
  2. The data cable…….. The SIG ECHO1 has some GREAT features including the ability to take pictures and wait for it……… design AND SHARE your own reticles! SIG has an online app for accomplishing this and detailed instructions. we will add the link below.

The SIG ECHO1 and ECHO1 B are essentially the same optic beyond the differences in included hardware etc.  Here are some more of the details taken from the product page over at Megiddo Tactical Group (MTGtactical.com)
