This is C-pod Lite.

The C-pod Lite is a powerful GPS tracking device. The small unit is about the same size as a deck of cards, which makes it easy to hide, and it is perfect for tracking an outboard engine, a jet ski or any other valuable equipment.

A replaceable internal battery that will last for two years during normal* usage powers the C-pod Lite. The unit sends its position automatically every 6 hours and if it moves more than 50m (54yd) an alarm is triggered and the device will start sending its position every 5 min.
The alarm is sent via push notification, SMS and/or e-mail and the number of recipients is unlimited. The C-pod Lite has a built in SIM-card with global coverage.

*Normal usage is defined as the unit communicating four times during a 24 hours period.
