We are affiliated with the Payfinder gas detector. Payfinder increases the accuracy of data, safety on location, reliability of the hardware and usability for the geologist. With the patented all in one design and inertial bypass filtration system, Payfinder has been able to reduce the overall size of the unit, reduced the "in system" lag time, reduce gas dilution with a low volume filtration design, and therefore increase the accuracy of data particularly under fast paced drilling conditions. This provides better data resolution to help clients avoid bypassed payzones, more readily see connection gases, pick fracture points and steer horizontal drills to maximum production output.
