SeekTech SR-60

Measuring Depth (Line Tracing Modes)

The SR-60 calculates Measured Depth by comparing the strength of the signal at the lower antenna to that at the upper antenna.

Measured Depth is measured correctly in an undistorted field when the bottom antenna is touching the ground directly above the signal source and the antenna mast is vertical.

1.To measure depth, place the locator on the ground, directly above the Sonde or the line.

2.Measured Depth will be shown in the lower left hand corner.

3.Measured Depth will be accurate only if the signal is undistorted and the antenna mast is held vertical.

Testing for the consistency of the Measured Depth reading can be done by raising the SR-60 a known distance (say, 12 inches (33 cm)) and observing whether the Measured Depth indicator increases by the same amount. Small variation is acceptable, but if the Measured Depth does not change, or changes drastically, it is an indication of a “distorted” field, or very low current on the line.

Push-Button Depth

Holding the Select Key will display a short count- down followed by a calculated depth report. This “Pushbutton Depth”, calculated on more signal samples, will be more precise than the running Depth indication.

Push-button Depth will generate a brief count-down screen followed by a calculation screen, which changes to a depth report screen when the calculation is complete.

Depth Warnings

NOTE: Exposing the utility is the only way to verify its existence, location, and depth.

Certain conditions make depth readings less precise or less reliable. When using Pushbutton Depth, a warning will appear when these conditions occur:

Motion of the SR-60 during sampling

Depth is varying greatly

Signal Strength is varying greatly.

Extreme offset between guidance line and tracing line (right or left).

Clipping (Signal too high). Averaged depth will be inaccurate.

Distortion level too high to read depth accurately
