1, more real measurement data, solved many traditional positioning cannot solve the problem;

2, provide convenient eccentricity compensation program, function more complete.

3, the reflector (target) in the precision components, one-time factory calibration, without calibration on a regular basis; Easy to use and maintenance;

4, no cable drag and drop the worry, no charge, no replacement battery trouble, no signal don't get troubles;

5, target disk without electronic components, more stable, low failure rate, long service life;

6, without obliquity sensor, has nothing to do with gravity, easy to other additional equipment requirement;

7, measure with the chassis height completely unrelated, easily measure low chassis of the vehicle;

8, easy maintenance.
