Sea Lion Locator Beacon Housing (2010)

A group that uses captive California Sea Lions operating freely in a lagoon that is connected to the ocean needed to be able to track individual animals by use of a tracking device. The device uses GPS to determine its position (on the surface, not underwater) and transmits that position back to the handler.

The housing was made out of 1.5-inch PVC pipe with an acrylic door that is attached to a Nylon harness on the animal. The PVC door uses a single o-ring bore seal and employs a string closure.
