A sonde is a miniature transmitter that is battery operated and omits a specific frequency your locator will receive. A sonde gives the ability to locate nonmetallic pipe. A sonde goes in the pipe and transmits a signal.

vLoc3-Cam Locator

The vLoc3-Cam is the easiest to use sonde and camera locator on the market today. The omni-directional antenna array allows for approaching the sonde from any position. Simple to decipher, directional arrows direct the user through the bright colour LCD display to the accurate location and depth of the sonde or camera.  The sonde is displayed as a picture on the display for ease of identification.  This new technology with its two sets of 3D antennas provides consistently accurate results with the simplest interface available on the market.

The vLoc3-Cam includes multiple sonde frequencies making it compatible with the major push cameras and crawler cameras on the market. The Pushrod Trace mode shows a second display geared for tracing the path of the pushrod deployed in the pipe or tracing pipes with an optional portable transmitter. 

The vLoc3-Cam comes with two Passive locate modes of Power and Radio which will detect the presence of live power lines, CATV, telephone and some metallic pipes which radiate 50/60 Hz from nearby or overhead power lines. For active locating, with the use of a portable transmitter, the vLoc3-Cam comes with an 83.1kHz frequency for tracing the pushrod. This frequency is also ideal for water and gas utilities which generally are larger pipes with bell housings and gaskets as well as locating ungrounded small diameter drop wires and inducing signals through the soil, onto services when direct connecting is not an option.
