Replacement for the DistoX2: A Project in Progress

The DistoX2 survey instrument has been key to accurate and efficient cave surveys. It was discontinued at the end of 2019; an electronics project was started to design a replacement. This ongoing project has investigated 19 digital compass MEMS sensors (Micro-Electro Mechanical System) and selected three devices to compare against the sensor used in the DistoX2. A turntable was designed to look into any non-linear behavior. This led to selecting a sensor for future development.
