cavity probe

Cavity probe’s signal resistance is small , it can improve the accuracy of orientation. Mud flow area is the large , thus it increase the displacement, and lower cycle pressure, improve the ability of the mud return sand. There is special damping devices in the cabin, which make a better shock absorption effect ,so that it protect cavity probe against shocks effectively, and extend the working life of probe. It is easy to dismantle and install , which save times. The working life of cavity probe is pretty long.
