DTG-E2 is designed for borehole drilling, it has overcome the technical difficulty: low working temperature. Inertial devices are more adaptable and better applied in the drilling field than they are in aviation field due to its ability of working in poor conditions. The life of DTGs and its adaptation in temperature are specified, especially when it was used in higher temperature.
