TDR10-X-340 Product Information



Wildlife Computers Time-Depth Recorders (TDR) are data-archiving tags designed for tracking fine-scale movements of marine animals. A TDR10 is a cost-effective tag that works best on animals that can be captured twice such as pinnipeds, sea turtles, and penguins.


The TDR10 tags come in a variety of shapes with a variety of sensor options for gathering sample data including depth, temperature, light, wet/dry, acceleration, and stomach temperature (using the stomach temperature pill linked to a TDR). TDR10 tags can also come equipped with Fastloc® GPS. Fastloc acquires highly accurate locations in under a second.

Recovery Options for TDR Tags

    • Payload Recovery Device—a great way to recover data with minimal effort and disturbance. From over 200 m away, the Payload Recovery Device will detach from the animal with a radio command.
    • Float Packages—if you cannot recapture your animal another option is to attach the TDR10 to a float package that will release from the animal and then recovered. For example, a suction cup attachment on a cetacean. A SPOT tag, like our Asset Recovery tag, can be used to assist in finding the float package.
    • Asset Recovery Tag—A SPOT tag can be attached to the animal in order to locate it, recapture it, and recover the TDR10. This tag can also be incorporated into a float package that holds the TDR10.
