Pulsed Eddy Current Underwater Probes

See what’s really going on subsea

Eddyfi Technologies offers underwater Pulsed Eddy Current (PEC) probes specifically designed to detect corrosion hidden under marine growth or coatings. Measure remaining wall thickness without surface preparation in offshore applications such as risers, jetty piles, caissons, and underwater piping systems.


  • Tackle offshore applications
  • Go as deep as 100 m (330 ft)
  • Enjoy embedded control LEDs
  • Inspect components up to 100 mm (4 in) thick
  • Examine through marine growth up to 305 mm (12 in) deep
  • Choose 50 m (165 ft) or 100 m (330 ft) cable


Underwater probes can tackle offshore inspection applications, even through marine growth requiring no surface preparation. Eddyfi Technologies’ underwater PEC probes are watertight 100 m (330 ft) deep and feature a long cable. These probes are operated with the proven Lyft® PEC system.

The status LEDs embedded in the probes ensure better control and synchronization of the diver with the topside inspection team. Diver deployed inspectors can scan components as thick as 100 mm (4 in) as well as insulation and marine growth as thick as 300 mm (12 in).

At Eddyfi Technologies, we understand the critical importance of maintaining the integrity of underwater assets. That's why our underwater pulsed eddy current probes are designed and built to the highest standards of quality and reliability. With our advanced PEC inspection solutions, you can detect corrosion and defects in underwater structures quickly and accurately, ensuring the safety and longevity of your assets. Choose Eddyfi Technologies for the most advanced, effective, and dependable inspection solutions available for underwater environments.
