Soviet night vision monocle. The main difference between this model and the simpler and earlier PN-1 is a built-in ultraviolet flashlight with the ability to focus (turned on by a toggle switch). Aa batteries are inserted into the handle. Will be already inserted – as a gift Full factory set. You can also connect 12 volts to the car’s onboard network.. But you need to know the polarity (I have not tested it). Do not turn on by light with the cover removed – you can damage the electronics. Tested by me, works great. Time capsule – very few of these things have survived to our time in such a wonderful state. It will be a great gift for an antique lover or to add to your collection. If you have questions, ask me. I would be glad to answer all your question. You get what you see. Will be delivered to you as quickly as possible! ANY DEFECTS NOT MENTIONED BUT VISIBLE IN THE PICTURES WILL BE CONSIDERED AS DESCRIBED. PLEASE DO NOT FORGET TO GIVE YOUR FEEDBACK. YOUR FEEDBACK IS GREATLY APPRECIATED. Peaceful sky to you. And God bless you.
