As stated on the foreign resource Defense Blog, the Ukrainian military allegedly got into the hands of the Spider laser radiation detector used by the Russian army ("Spider"). Along with the previously received information about the intention of the Armed Forces of the Russian Federation to acquire this novelty, this indicates the beginning of equipping the troops engaged in the SVO with personal means of detecting snipers and drones.
The device weighing 150 g is placed on the helmet (or other parts of the ammunition) and recognizes laser radiation with a wavelength from 0.8 to 1.7 microns, in the range of which all known rangefinders, illuminators and designators work. When a threat is detected, the fighter is notified in three ways – voice with vibration (indicating the direction from which the danger comes – "left", "center", "right"), light (thanks to the LEDs located inside) and combined.
Two batteries allow the Spider to work for 12 hours at temperatures from -30 to +40 degrees.
Mainly, the "Spider" makes it possible to reduce the threat level from drones: UAVs activate laser rangefinders, which are part of the optical surveillance unit, when conducting reconnaissance. They are also used in sniper complexes.
