BrickHouse Security resident Security Specialist Gina Mobilio takes a look at the Spark Nano. This is the world's smallest and most powerful GPS real-time tracking device available that's water resistant, battery powered, and completely covert. Use it for gps vehicle tracking, or tracking an employee or family member. With unlimited tracking, this super sensitive GPS tracker will continually track even in low reception areas where other GPS trackers fail.
