Push the right arrow to Y for Yes, and push the execute button. You should now see that the Yaw Ref
number at the top of the screen matches the Yaw number at the bottom of the screen as shown here. The
Yaw Ref and Yaw are also graphically displayed by a dashed vertical line with an arrowhead and a long
rectangular box, respectively.

SST Remote Screen Showing New Reference Heading
NOTE: If possible, take a Ref Yaw reading at a different location along the borepath, and/or at
the exit location. This will allow you to determine an average Ref Yaw over the borepath
and possibly identify variations in the Yaw that could result in inaccurate readings.
When the SST transmitter’s Yaw does not match the Ref Yaw the tool icon will be to the left or right of the
dashed line and a corresponding number will display above the tool icon to indicate the number of
degrees that the SST is off line, as in the example shown below. In this case, the heading of the SST is
60.7° off of the reference heading, which means the tool needs to be steered left 60.7°.
