long viewing distance and high quality of image, which was confirmed during operation of the sight installed in the tank in various seasons and in various climate and terrain conditions;
small dimensions, which enable the sight to be installed in newly-manufactured vehicles , as well as in vehicles being upgraded;
modular design (thermal camera, micro-monitor, control panel, display screen, head mirror control panel);
simplicity and ease of operation;
reliability.
