The YB3i - Permanent installation tracking system, with backup battery.


The YB3i Two-Way Messenger is a truly global communication device and tracking system.


It is a permanently installed unit which uses the Iridium satellite network to transmit your messages, and your location, from anywhere in the World.


The picture shows the unit mounted on a rail using the optional Rokk Mount, which can be purchased separately


After purchasing a YB3i unit you will need to activate it online and purchase credits before the unit will operate.
