KiwiSat® Fin Tag Series

Low power transmitters afford small size for lightweight deployments

The KiwiSat® 202 fin-mount is designed for short to medium term monitoring of released rehabilitated or refloated stranded cetaceans.

Models with optional DIVE sensing send data on the most recent dives whilst maximising the number of transmissions.

At a Cetacean Tag Design workshop hosted by the Office of Naval Research and the Marine Mammal Commission, the single pin mounting was considered to be the least invasive for this type of monitoring. Combined with minimal frontal area this attachment has proved to be a success.

One model is fitted with a VHF transmitter in addition to the Argos transmitter to allow the researcher to locate and visually monitor the study animal at sea.


  • Wet/dry sensor, flexible scheduling and haul-out mode
  • Local area tracking with built in VHF transmitter (K2F 172B only)
  • DIVE sensing
  • Product Application Examples

    Our range of fin tags are ideal for monitoring the location of sharks, dolphins and porpoises as well as monitoring post stranding survival of large cetaceans. The KiwiSat® K2F 176D fin-mount is primarily intended for tracking sharks.
