The color of the confidence circle also changes depending on the degree of confidence:
Green - Low distortion/high confidence.
Blue - Minor distortion/medium confidence, so please proceed with care.
Red - Excessive distortion/low confidence. Treat all data and measurements with caution.
7. Notice that vertical and horizontal distances from the target line are displayed.
1.43m
1.86m
These must not be mistaken for the distance diagonally to the target; such information is not displayed. The vertical distance
is the true depth from the bottom of the locator. The advantage of this is that the target's depth and position can be determined
without being directly over the target line. So, in the event of an obstruction at the measuring point, data can still be gathered by
placing the locator on one side of the target.
2.11.2 The Transverse Graph Screen
The Transverse Plot screen is used to analyze the field shape at a particular location, enabling the user to better feel for the
data's reliability.
Two plots are generated simultaneously.
• Peak response
• Null response
In non-distorted fields, the peak and null positions should coincide, and the shape of the fields should be symmetrical about the
centerline. The picture below shows a slightly distorted field.

Using the Transverse Graph Screen
To take a plot, first, locate the target using one of the other locate screens. Now select the Transverse screen by a long press of
the return button. Repeat this until the Transverse screen appears.
Position yourself to one side of the line such that the field markers are just on the screen. You will see that the lines automatically
remove themselves after a set period of a few seconds. Clear the screen by pressing the “ –” button. Now walk across the target
line at a steady pace until you are on the other side of the target line. Immediately press the “+” button to save the plot on the
screen.
It is still possible to walk back over the target, locating the line's position in the transverse screen while still retaining the saved
screen.
