The Sig Sauer ECHO R Series Thermal Scope is a variable power thermal optic that resembles a traditional rifle scope. With 12 hours of runtime, you can stay out all night finding and chasing game. The high resolution sensor will clearly show you your target and the built-in BDX technology allows you to connect this scope to your other BDX enabled Sig optics to give you ballistic readings and other important data needed to make an accurate shot.
