The REFLEX GYRO™ is a complete downhole surveying instrument capable of surveying in all environments, magnetic and non-magnetic. With proven reliability and accuracy, it utilises a digital surface referenced MEMS-gyro.

Survey data, once brought to the surface, can be transferred from the on-board memory to the field PC via a high-speed bluetooth connection. The full set of data readings can be processed using the advanced REFLEX GMIT5™ navigation software, where users can tabulate, plot and export data into various formats for enhanced decision making.
