DIGITAL MATTER Oyster3 GPS Tracker 4G / LTE-M / NB-IoT / LTC battery support

Built for extreme longevity and rugged deployments, the Oyster3 4G from DIGITAL MATTER stands apart from typical GPS trackers with its support for Lithium Thionyl Chloride (LTC) batteries, enabling up to a decade of field life on three AA cells. Unlike rechargeable-only devices, this tracker thrives in remote, unattended installations where power access is limited or non-existent. Its IP67-rated enclosure, advanced GNSS engine, and dual-mode cellular connectivity make it a dependable choice for asset, fleet, and equipment monitoring across harsh environments.

Highlights

• 4G LTE-M / NB-IoT connectivity with 2G fallback for broad network coverage
• Powered by 3 x AA LTC batteries for up to 10 years of operation (configurable)
• Multi-constellation GNSS: GPS, GLONASS, Galileo, BeiDou, QZSS, SBAS with A-GPS
• Rugged IP67 housing in ABS/polycarbonate, operating from -30°C to +60°C
• Built-in 3-axis accelerometer and temperature sensor for tamper, impact, and environment monitoring
• Large internal memory for up to 50,000 records, with over-the-air firmware updates

In daily use

Deploy the Oyster3 4G on trailers, generators, containers, or any high-value asset that must be tracked for years without battery swaps. The accelerometer enables motion-based reporting, so the tracker can sleep between events to conserve power, then wake instantly on movement or impact. Geofencing alerts keep you informed of unauthorized use, while the temperature sensor helps monitor cold-chain or equipment conditions. With screw, cable tie, or optional magnetic mounting, installation is flexible and secure. Configuration and firmware updates are performed remotely via FOTA, minimizing site visits.
