One thing that people consistently ask me for are good military surplus binoculars. They have more uses than military applications, such as bird watching, hunting, or just admiring nature from afar.
These are built very tough, and are encased in a heavy duty rubber coating to provide some resistance to moisture. I inspect each pair to make sure the glass is crystal clear and free of cracks and such. The rubber may have some dirt/discoloration from use, but all are inspected for functionality, and you will receive a complete and functional pair. It was VERY hard for me to not hoard them all due to the quality. Most I've seen are dated in the late 1970s. Sources have said these were used up until the early 2000s. I can definitely see why.
These apparently have an Infrared filter that is engaged by a small lever on the left monocular. This flips the filter in to view. I have no idea how this works yet, but that's what sources all corroborate its function is. Just another added bonus I guess right?
The photo of the trees was taken pointing at 1000 yards from where I was standing. These are really high quality, and are WAY more affordable than a modern day equivalent. Don't wait too long before these are sold out forever!
