Electronic Single-Shot Survey Tool
With fully integrated accelerometers and magnetic sensors, the Electronic Single-Shot (ESS) Survey Tool is designed to collect digital directional survey data that can be read and analysed using the rugged handheld device to output attitude parameters.
When employing GPS technology, borehole trajectory measurement can be conducted within a designated time and location range by activating a specific probe, further improving data accuracy and reliability.
