Especially for self propeller howitzer DANA is designed panoramic telescope PG-1M-D M64 for connection with ZZ-73 M64.
The panoramic telescope PG-1M-D M64 is an optical instrument which serves for sighting for azimuth. As an periscopes instrument it enables a circular(panaromic) observation. As at such an observation the eyepiece of the panaromic telescope remains fixed, the gunner in relation to the weapon takes a strictly specified place at any position of aiming point.
Modification results in a more precise distribution of horizontal and vertical scale from the original 60-00 dc to 64-00 (NATO and USA standard). The original reticle in PG-1M M64 is replaced by new one with a modified horizontal and vertical axis.
