BTW, you may have saved yourself throwing money away. $2K for thermal isnt going to buy a whole lot. Better than the <$1K stuff but the better quality thermal and IR optics are going to start above $3K. Buy once, cry once.
Do you have experience with ATN Thor IV? say the largest objective, and highest power?
What is so much better it is worth the extra money, and how is it different, in terms of range, identification, etc?
