isCOMPASS
Based on modern MEMS technology The
isCompass is a magnetic multishot instrument for borehole surveying
based on modern MEMS technology. It is fully integrated in its own
brass running gear, requiring little set-up in the field. Wireless
in operation, the tool utilizes infrared communication with a
rugged handheld field computer. isCompass is powered by standard C
battery cells and will operate for more than 100 hours on seven
batteries, which can be changed by the operator. Data is
transferred from the handheld control unit to another computer
using a standard USB memory. The system can be run in both single
and multishot modes.

isCompass specifications 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.
isCompass - control and processing The
isCompass is delivered with a rugged handheld computer, the Nautiz
X5, running Windows Mobile 6.1. All operations and downloaded data
are processed by the computer and can be viewed directly on the
handheld device. Quality measurements of survey stations are also
provided.
Multishot or Singleshot option The
isCompass is available in multishot and singleshot versions.
