How do I locate a Camera Head or a Sonde?

Viewed 140 Times

You locate a camera head in the same way that you locate a Sonde:

  1. the Receiver’s blade has to be parallel to the camera head or sonde;
  2. the frequency on the Receiver has to match the camera or sonde’s own frequency;
  3. the SONDE ICON must show in your receiver’s display.

Typical frequencies for cameras or sondes are 512 Hz or 33 kHz. If your frequency does not show up in your Receiver’s display, then you may have to enable it through the Receiver’s Menu options. For more details on how to access the Receiver’s menus please refer to the Receiver’s User Guide or contact Eastcom for help.

Pinpointing the location of the camera or sonde is a two (2) step process, the Receiver’s “blade” has to be parallel to the camera/sonde, and in the PEAK mode.

STEP #1

Due to the shape of the signal that a camera or a sonde emits, you will be locating three (3) peaks spread out longitudinally along the path of the camera/sonde, the center peak being much stronger than the two outer peaks (which are also called “ghosts”).

STEP #2

After locating the center peak walking ALONG the path of the camera, you now need to start locating ACROSS the path. Move in one direction ACROSS and see if your bar-graph grows or falls. Follow the direction of growth until you find the absolute peak.

The camera or sonde will lay directly underneath the center peak response. Observe the DEPTH that your receiver indicates.

Please contact Eastcom if you have any questions or you need help in locating a camera or sonde.
