OK all I can say is "Armasight" and "FLIR" however FLIR has now ownership of Armasight. Doesn't matter, large selection and a quality product. Be advised.......you get what you pay for. I have a "Spark Core" and a "Vampire Core"

Both I can say are excellent tools. If I paid that kind of money and was not happy I would be bitchin up a storm. I wasn't happy with the 1st mono I got so they took it back no questions and sent me a spark, waaaaaay much better. If you lived closer I'd let you view them yourself.

Just go for thermal..........take the plunge and you'll never look back, he, he.......
