12.3.1.6 Linear Time Gain
As described in Section 12.2.6: P.73, the weak signals must be amplified or “gained” to see them
on the display. The Gain button described in Section 12.2.6: P.73 can be set to a value from 1 to
9 depending on the amount of gain required (1 is lowest gain, 9 is highest gain).
on the display. The Gain button described in Section 12.2.6: P.73 can be set to a value from 1 to
9 depending on the amount of gain required (1 is lowest gain, 9 is highest gain).
There is also a second level of gain available to the user and that is the Linear Gain setting. The
default Linear Gain setting of 2.0 is usually adequate for most ground conditions, however, if
advanced users find that they are surveying in areas where high Gain button settings are always
required to see data, it may be advantageous to increase the Linear Gain setting. Conversely, if
the user finds that low Gain button values work to see the data, it may be useful to decrease the
Linear Gain setting.

For the experienced user, the setting indicates the gain increases per nanosecond.
The Linear Gain setting can vary from 0.0 to 5.0 in steps of 0.5.
12.3.1.7 Position Units
This is the setting for the position units used by the odometer. The available options are:
1) metres (default)
2) feet
