5.6 Completing a deployment
When you feel the Boretrak2 probe touch the end of the borehole, keep the steel cable tight so that the probe
remains upright with respect to the hole.
Tap Final Reading to take the final reading in the borehole.
The Final Offset controls appear.
Commonly, when the probe reaches the end of the hole, the last deployment interval does not equal the full, user-
defined Segment Length. In this case, while the probe is at the end of the hole, keep the cable taught and measure
the distance from the hole collar back along the cable to the next measurement point, i.e. the next interval / nodule
/ rod joint to which you would deploy if the hole were longer.
