The Watermark is a graphic representation of the highest Signal
Strength reached (in Sonde mode) or the highest Proximity Signal
level reached (in Line Tracing modes). It is "chased" by a solid
Level Pointer
which shows the current Signal Strength. If the
Signal Strength Level Pointer goes higher than the Watermark,
the Watermark moves up accordingly to show the new highest
level graphically. The Watermark, like the high-water ring in a
bathtub, shows the highest level reached.
This provides an additional, visual way to track the maximum sig-
nal. If you are trying to trace a line by noticing its highest Signal
Strength level, Watermark serves as a visual aid.
The Watermark and Race Track are a single option that is off
by default but can be set on in the Display Elements selection
menu.

No-Signal Icon (Suppression)
IF this feature is selected "on", when the SR-60 is not receiving
any meaningful signal on the selected frequency, it will display
a moving magnifying glass icon, indicating no signal is being
detected (Figure 55). The sound will also mute when no signal is
found. This reduces the confusion of trying to interpret the ran-
dom noise that some locators display in the absence of a signal.
Depth suppression – If the Measured Depth is greater
than the threshold depth (by default, 99'/30 m in Sonde
mode and 30'/10 m in Line Trace mode), the map is
suppressed, and the magnifying glass appears.
Noise suppression – If the signal is seen to be too noisy,
the map may also be suppressed.
Center Signal Strength Option
Selecting this option in the Menu Selection screen will force
the number representing Signal Strength to be displayed in the
center of the display area anytime when a Proximity Signal is not
available (Figure 56). This may occur when signal is weak. When
a Proximity Signal again becomes available, the Signal Strength
number returns to the lower right corner of the screen as usual.
(Line Trace Mode only).

Signal Focus Control
The Signal Focus Control feature essentially acts something like
a magnifying glass on the signal. It reduces the sample band-
width of the signal that the receiver examines, and gives a dis-
play based on a more sensitive read of the incoming signals.
The tradeoff in using the Signal Focus Control setting is that the
display, while more precise, will update more slowly. The Signal
Focus Control can be set at 4 Hz (wide), 2 Hz, 1 Hz, .5 Hz, and
.25 Hz (narrow). The narrower the selected bandwidth used, the
greater detection distance and precision the receiver will show,
but with a lower update rate of data on the display.
