The tool outputs standard survey data, such as recorded station depth, inclination, azimuth, gravity highside, magnetic toolface, temperature and more. The magnetometers have been calibrated with high precision and the tool will deliver a reading of the magnitude of the local magnetic field which can be used to detect anomalies in the local Earth magnetic field to identify survey stations of low quality.

Local magnetic declination and start coordinates can also be set directly in the handheld unit. The OD of the fully-integrated running gear is 35 mm and the system is supplied with three aluminum extension rods to allow the operator to get the gear through and away from the drill bit.
