Frank,
Iirc, a Patrol lists for $6,500 and IR Defense does not have a new one out. But IR D has had the best view through their thermals since their 12 micron 640 core came out, three years ago.
Taco, I don't disagree, but for a guy looking to equip himself now with thermal's now the 12 micron 640 Q14 at $4k is very attractive, and at $2k so is the 320 version.
