How to use SeekTech SR-20 Utility Locator

The RIDGID SeekTech SR-20 is a utility line locator used to find and trace the paths of underground utility lines such as water, gas, and electrical lines. To use the RIDGID SeekTech SR-20, follow these steps:


Make sure the SR-20 is fully charged.
Familiarize yourself with the device and its components: receiver, display, and keypad.
Power on the receiver:

Press and hold the power button until the device turns on. The button is located on the keypad.
Select the frequency:

Use the keypad to choose the appropriate frequency for the utility line you're trying to locate. Common frequencies are 128 Hz, 1 kHz, 8 kHz, and 33 kHz. Consult the utility company or your specific situation to determine the best frequency to use.
Adjust the gain:

Gain is the sensitivity of the receiver. Adjust the gain using the up and down arrow keys on the keypad. Start with a higher gain setting and lower it as needed.
Hold the receiver correctly:

Hold the receiver vertically, with the antenna assembly pointing down, and the display facing towards you.
Start searching for the utility line:

Walk slowly and methodically in the area where you suspect the utility line is located. Keep an eye on the display, which will show signal strength and directional guidance. The signal strength bar will increase as you get closer to the utility line, and the directional arrows will guide you along the path.
Follow the utility line:

Once you have found the utility line, follow its path by walking in the direction indicated by the arrows on the display. As you walk, the display will show the estimated depth of the utility line. Periodically check the depth reading to ensure accuracy.
Mark the utility line's path:

Use marking paint or flags to mark the utility line's path on the ground as you trace it.
Power off the receiver:

Once you have completed your task, press and hold the power button to turn off the SR-20.
Remember that it is essential to follow all safety precautions and guidelines when using the RIDGID SeekTech SR-20. Always call your local utility companies to have them mark the utility lines before you begin any digging or excavation projects.
