Features 1、The use of a fully shielded structure greatly suppresses electromagnetic clutter interference in the external environment and improves the dynamic range of the entire system. It is beneficial to improve the detection accuracy of the position. It is a veritable magnetic field probe. 2、The handle portion is also shielded, reducing the impact of the hand on the probe. 3、Increased thickness for improved hand comfort. 4、Wider bandwidth. InTheory, the frequency can be muchhigher than 7GHz, and the performances of 7G or above is unknown due to the limitations of the test equipment. 5、Made of fine quality materials with fine workmanship, sturdy and wear-resistant, perfect performances, easy to use.
