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.
Different tag models offer different data products.

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.
The TDR10 is configurable with a wide variety of sensors. Fastloc® GPS is available on several configurations.
