Animal and telemetry data are priceless but recovering that data can be challenging. A payload recovery device is the best way to recover your data with minimal effort and disturbance to the animal. Designed for pinnipeds, the PRD-RP (Payload Recovery Device-Remote Pinniped) can survive onshore abuse and depths up to 2,000 meters. There are many ways to find the device including Argos locations, a strobe light, or a UHF beacon. The PRD-RP can be used multiple times so the same valuable payload can be used again right away. The PRD-RP is the only commercially available release system suitable for deployments on seals, sea lions, and fur seals. As a bonus, there are no shipping restrictions with the device, unlike other squib-style release mechanisms.



  • Remote release—radio triggered release from over 200 meters.
  • On-demand—the researcher initiates the release.
  • Rugged—can withstand the abuse of large animals on the rookery.
  • Multi-use—field refurbishment allows for multiple deployments.
  • Recovery aids—Argos locations, UHF radio beacon, and strobe light.
  • Generic payload platform—any device can be carried, limited only by size.
  • Pressure rated—can survive up to 2,000 meters.
  • Shippable—no shipping restrictions.
