5.5 Bluetooth connection
When the Boretrak2 probe starts a survey, there is a live Bluetooth link between the probe and the tablet. While the
live link is retained, data is ‘silently’ downloaded from the probe to the tablet, approximately every thirty seconds.
Soon after the probe enters the borehole this link will probably be lost as the Bluetooth signal cannot pass through
rock.
With the link broken, the Disconnect button automatically changes to Reconnect. The live Heading and
Inclination display disappears.
Continue with the deployment as before.
