80 Type five-use military compass
This model is newly designed one. It can be used for measuring orientation, distance, pitch angle, mileage and map coordinate.
The Luminious marks ensure orientation and pitch measurements at night.
Specifications:
The orientatin graduation
Outer circle: 60-00mil system;
Per unit: 00-20 mil
Inner circle: 360 degree system;
Per unit: 2°
Accuracy: ±00-10mil or ±1°
Distance finder
There are two ways to estimate distance, i.e, proportional finder is composed of PROPORTINAL-RULE and SIGHT with a ratio of 10:1. The mil finder is made up of MIL RULE and SIGHT.
Accuracy: 5%
