I’m looking to pick up a thermal scope for critter control (hogs, coyotes, etc) and have a line on one of Sigs Echo units. Anyone with firsthand knowledge on these? I’m also looking at some of FLIRs offerings, but am leaning towards the Sig. Any advice/input would be appreciated. I’m no operator, but reliability and ruggedness are important, after all I’ll be using this outdoors and trecking around in the dark.
