6 Re-aligning
The gyro accuracy degrades over time after an alignment. You should carry out a re-alignment
as often as possible. For the very best accuracy, realign before each hole. A reasonable target
would be to align every three or four holes, but this will depend on the length of each deployment,
the required accuracy for your project and the practical realties of positioning the alignment jig
on your site.
Carry out a realignment between deployments, while you can see the
