-1.1kg and it works from 20cm near to infinity 🙂

Used is a Takumar SMC.

I have a PN-1 night vision device here from the Soviet Union; despite being equipped with a V2-A tube, it offers no more brightness than my naked eye and detects infrared light poorly—or barely at all. My PN-3 (Gen 0) unit, on the other hand, makes everything appear extremely bright when using infrared illumination. Is the tube in this unit simply past its prime, or is the voltage from the power converter incorrect?

I mean its YOUNGER than my PN 3 .
