6.2 The Sighting Scope
A sighting scope (739870) is available as an optional accessory for
alignment of the axes and second day setups.
The scope is magnetically mounted to the top of the housing and once
aligned has a repeatable accuracy of approximately ± 0.2°.
Alignment of the
crosshairs
If using the scope for reference or second day setup, use the raised
sights on the top of the laser to align your Rugby to a second control
point.
The scope is roughly aligned at the factory. If a more precise alignment
is desired, first align the Rugby to a second control point using the proce-
dure for Precise Alignment of the Axes found in this manual.
