How 512Hz Travels from Pipe to Surface

Emit
Cutaway pipe showing camera head emitting concentric 512Hz rings.

Propagate

Common Mistakes & How to Fix

Myth — EMI doesn’t matter
Myth — Depth is unlimited
Why Your 512Hz Locator Can’t Pick Up the Signal
If the sonde is on but your locator can’t detect it, walk through these checks.
1. Wrong Frequency Mode(Only for other brands,such as Rigid, because the frequency of Powerwill's locator is 512Hz)
Some multi-frequency locators can scan for 512Hz, 640Hz, 8kHz, and more. If your locator isn’t set to 512Hz, it simply won’t detect your camera head, because our sewer camera frequency is 512Hz.
✅Solution:
When you use other brands of locators with our power will sewer cameras, double-check that your locator is set to 512Hz mode.
2. Low Locator Battery
A weak battery may reduce sensitivity, range, and signal stability.
✅Solution:
Replace or recharge your locator’s batteries regularly. Avoid using partially depleted cells, especially in colder weather.
3. Improper Scanning Technique
Even with everything working, poor technique can cause failed detections. Moving too quickly, scanning too far above the ground, or skipping proper calibration can all lead to missed signals.
✅Solution:
Hold the locator close to the ground.
Sweep slowly and methodically. For more specific operation steps, please refer to the instruction manual or product details page.
Practice makes perfect—build a habit of slow, steady scanning.
4. Too Deep or Too Far
If the camera head is too deep underground or buried under dense material like wet clay, the signal can be weak or distorted. (Our 512Hz locator can receive the 512Hz transmission within 5 meters/16.4ft deep)
✅Solution:
Check the locator’s sensitivity settings.
Switch to a more sensitive model if necessary.
5. Electromagnetic Interference
Nearby power lines, metal structures, or even vehicles can interfere with low-frequency signals.
✅Solution:
Try to scan when the environment is free of large metallic or electrical sources. Move away from underground utilities or high-voltage areas if the signal seems unstable.
Preventative Tips to Avoid Future Issues
Test before the job:
Always test the transmitter and locator above ground before each job.
Keep components dry:
Even waterproof tools can fail if connectors or terminals stay wet.
Regular maintenance:
Wipe down the camera head and locator, and store them in padded, protective cases.
