PT9 C-PROOF
The legacy underwater locator beacon.

Established for years under hardest operating conditions.
The PT9 C-PROOF is a 30-day underwater locator beacon, which has been developed for installation on protective data capsules attached to voyage data recorder systems. The PT9 C-PROOF has been designed to send a locating signal for at least 30 days in case of being activated by water immersion.
The PT9 C-PROOF is the legacy beacon in the market for almost two decades.
The beacon consists of materials and coatings which have proved themselves in practice, having been exposed to the rough conditions on deck of a ship for years. It does not only have corrosion protected components as coatings and contact areas; but is also equipped with a patented, intelligent activation.
