I may be late to the party but I've just noticed OSA are now distributing another brand of thermal along with ATN. Seems they have "clip ons" and monoculars branded LIEMKE.
Don't know anything about them but good to see more competition. Quite a comprehensive list of options available to us mere ozzy's now. Makes the decision to spend lots of money that little bit more complicated.
Despite so many options now, our dreams of "affordable" thermal still seem a ways off.
Any average Joe's running some of the new stuff available feel free to chime in with your experience.
