Off-Time Tracking System: GPS + Logger

Model: GL-50-S & GL-50-BT

Overview

We provide an economic tracking method, the off-time GPS tracking system. This powerful GPS logger is embedded with SIRFIII GPS receivers and a non-volatile 8Mb memory, which allow 100,000 logs. It uses 3xAAA batteries and 2 power modes, the active mode and power-saving mode, are programmable by the utility supplied. While GL-50-S uses USB to navigate and download the logged data, GL-50-BT uses Bluetooth.
