Tilted Sondes
If the Sonde is tilted, one Pole will move closer to the Sonde
and the other farther away.
If the Sonde is vertical what is seen on the screen is a single
Pole at the point of maximum Signal Strength. (The Ridgid
Floating Sonde is designed to have a single Pole "visible"
and is weighted to maintain the Sonde on a vertical axis.)
Maximizing the Signal Strength will still guide to the best
location for the Sonde.
Floating Sondes
Some Sondes are designed to be flushed or to drift down
a pipe pushed by water flow. The only guarantee of having
located a floating Sonde is maximizing the Signal Strength
and double checking that the signal falls away on every side
of the maximum signal location.

Measuring Depth (Sonde Mode)
The SR-20 calculates Measured Depth by comparing the
strength of the signal at the lower antenna to the upper
antenna. Measured Depth is approximate; it will usually
reflect the physical depth when the mast is held vertical and
the bottom antenna is touching the ground directly above
the signal source, assuming no distortion is present.
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 of the SR-20's display screen.
3. A Measured Depth reading can be forced by pressing
the Select Key during a locate.
4. Measured Depth will be accurate only if the signal is
undistorted.
Clipping (Sonde Mode)
Occasionally the Signal Strength will be strong enough that
the receiver will be unable to process the entire signal, a
condition known as "clipping". When this occurs, a warning
symbol
signal is particularly strong.
NOTE: Measured Depth Display is disabled under clipping
conditions.
