Optional Features

Optional Features in the Display Elements Menu include:

• Race Track and Watermark

This provides an additional, visual way to track the maximum

signal. If you are trying to trace a line by noticing its highest

Signal Strength level, Watermark serves as a visual aid.

• No-Signal Icon (Suppression)

• 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.

• Proximity Threshold Control

This helps to constrain the locating to a certain range from

the instrument. If the Measured Depth of the target is greater

than the user-selected threshold value, the Proximity Signal

will read zero. If the Measured Depth is less than the threshold

that has been set, the SR-20 will display a Proximity Signal

value. (Line Trace Mode only.)

Figure 33: Proximity reshold Control

When it is activated, the Proximity Threshold is controlled

by a long press (greater than ½ second) on the Up Key to

set a higher threshold, or by the Down Key to lower the

threshold.

The settings on the Proximity Threshold control the depth

thresholding of the Proximity Signal as follows.

(Lowest) Signal Strength mode. Moves Signal Strength to

screen center, map display suppressed, allows negative

depth to display. Audio signal reects Signal Strength.

m/3 m/10 m/30 m) Displays Proximity Threshold for

detections where Measured Depth is Xm or less.

(Highest) Wide-open Proximity Mode. No threshold, no

suppression, allows negative depth display.

The Proximity Threshold Control is particularly valuable if

you need to eliminate signals from outside a well-dened

distance for clarity.

• Signal Focus Control

The Signal Focus Control feature essentially acts something

like a magnifying glass on the signal. It reduces the sample

bandwidth of the signal that the receiver examines, and gives

a display based on a more sensitive read of the incoming

signals. The tradeo in using the Signal Focus Control setting

is that the display, while more precise, will update more slowly.

he 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.

Figure 34: Signal Focus Control

When it is selected on, the Signal Focus Control is changed

to narrower or wider settings using the Up (narrower) and

Down (wider) Keys.

Signal Focus Control is useful when you need to focus in on a

particular signal with detail.

• Sound Muting > 99’

This option enables the automatic muting of the sound

when the Measured Depth is greater than the setting of the

Proximity Threshold setting.

• Tracing Line Response

The Tracing Line distortion response checkbox sets the

sensitivity of the Target Line’s distortion display to low,

medium, or high, or disables it altogether. The higher the

setting, the more sensitive the “distortion cloud” around the

Tracing Line becomes.

If the distortion response is disabled, the Tracing Line will

become a single solid line.

• Frequencies Selection Control

Additional available frequencies on the Master Frequency

Menu can be added to the Main Menu list of available

frequencies by going to the Frequency Selection Control

sub-menu

and selecting the desired mode.

Highlight the category of the desired frequency (Figure 35).
