Used, on a riser to be more comfortable when using. These go for around 2500$ new. Extremely neat technology. These can be used both during the day and at night time, to see heat signatures whenever. I have actually used it to track animals from the heat of their paw prints on the ground.
I tried getting a picture of the dog with my phone through the lens, however for whatever reason, the phone camera does not want to pick up correctly. The green line over the dog, is my phone's camera for some reason.
