Disclaimer: Limitless America loaned me their Sig ECHO3 so I could make this video. After I’d tried it out a bit, I pulled the owner aside and asked him if he wanted me to publish this, or just be like: “if you can’t say something nice, say nothing at all.” To their credit, Limitless America told me to be brutally honest.
If you find this video helpful, go to their website and buy a thermal rifle scope (not an ECHO) as a way to say thanks to them.
It might seem like I’m being mean-spirited, but this review is based on verifiable facts and I will screenshot everything for you. The specs on the Sig are bad, and my personal experience with this optic was not good. I know a lot of gun guys want to be unique and different, but if you’re spending 2,500 bucks up to 3,000 for a scope… maybe it’s not the time to be a special snowflake. It’s also not the time to be a just-as-good white knight defending the ECHO3…. Maybe if it was $1,300 -$1,500 it would be worth it. But don’t forget that the Sig is a lot more expensive than its competitors. Perhaps they overpriced it so at a glance you’d think it’s better… sadly that’s not the case. I’m really interested to see how this optic compares to the forthcoming Holosun thermal red dot.
Brace yourselves for the brutal truth: if you own an ECHO3, don’t ever look through an AGM Rattler TS25 384 core, because your friends will see you cry, hopefully it’ll be dark and you can blame allergies.

Sig ECHO3: Buyer Beware
The biggest YouTube review on the ECHO3 is from a large channel that is a paid shill for Optics Planet. The guy tells everyone that this optic is good-to-go and happily shares his discount code with the audience. If you listen carefully though, you’ll realize that this guy has only used cheap handheld monoculars, not other thermal scopes. So yeah, compared to an $800- handheld device that you can’t mount on a gun, the ECHO3 is cool. But, when you actually compare the Sig to other scopes like the AGM Rattler, the Sig becomes a sick joke. Other people who like the ECHO3 appear to be GWOT veterans who remember thermal tech from 10-15 years ago (cat’s butt nods meme). But, thermal technology has gotten WAY better (stonks meme) over the last few years.
I’m comparing this optic to competitors because value is always relative. Think about it, if you had a Mosin Nagant back in the revolutionary war you’d be amazing. But, is it really a top choice for the 21st century?

Closing thoughts:
While the form factor on the ECHO3 is kind of interesting and unique, the problem is that this scope costs a lot more while giving you a lot less performance.
I don’t have more footage with the ECHO3 because it only records for 30 seconds at a time and the image quality is so bad that you just want it to stop even sooner. If you bought this scope, I’m truly sorry. But, I just cannot morally recommend this scope. The only reason why it’s still listed for sale is probably because thermal optics are rare and opportunities to try them out side by side are extremely rare.
I hope the guys at Limitless America can forgive me for this: the owner is based, so go support them by ordering from them.
Thank You.
