I'm giving them options for their price point. also that ts19 is not a bad option for a 1k thermal. it's the best sub 1k thermal on the market. I mean you could purchase a pulsar 6,000 or a Ricoh for 10,000 - 20,000 but that's not the budget they stated. it's a great option for sub 100 yard thermal.
If you want the up-most authority on Night Vision and Thermals I would suggest:
https://www.youtube.com/@TheLateNightVisionShow/featured those two guys are the best online 'peeps' about those two technologies.
if you have questions, you can call them, and they will guide you.
if you are looking at Night Vision and/or Thermal look no further.
They are class acts. 100%
