Features:

1）Center rod use imported material, high precision and wear proof:

2）Shell use super hard aluminums, protect instrument from damage on site work and prolong use life;

3）Pointer slider is outside ring structure, easy to adjust friction, and assure equal friction between pointer slider and axis. And assure the precision of instrument, compare with similar other brand product, it’s good precision, longer use life and better price.
