Panoramic Periscope Sight PG-1M is designed to enable precise laying of artillery weapons in the vertical or horizontal plane during direct fire and from covered positions. The adjusting mechanism provides horizontal and vertical laying by the means of coarse and precise reading scales. In low visibility conditions such as smoke, snow or rain, the panoramic periscope sight is used along with a Gunner Collimator К-1 (optional). Specific scales for use with the collimator and side-corrections during direct fire are included in the set.
