LED-indicator transmitter sonde, abrasion-proof, that emits a 512 Hz signal detectable with any compatible locator to identify the transmitter position underground. The flashing LED confirms the sonde is transmitting. Its seamless injection-moulded design provides greater resistance to impacts, and its waterproof abrasion-proof coating prevents rust and corrosion, extending its service life. Includes two replaceable connectors that allow it to be coupled to drum machines or sectional cables, providing versatility for locating underground pipes.
