Oyster Cellular Long-Life Battery GPS Tracker

The Oyster is a compact, rugged GPS tracking device that has been designed for tracking containers, trailers, skip bins, and other assets where super-long battery life is required without sacrificing the frequency of updates and performance.

By utilising the latest technology, the Oyster can operate in ultra-low power modes, and with an incredible battery life of up to 5 years the Oyster Cellular can be attached to assets and tracked without needing to change batteries. The Oyster has built-in antennas for GPS reception and for cellular communication, a 3D accelerometer, a high-performance GPS that can track both GPS and GLONASS satellites simultaneously and flash memory for storing non-volatile information.
