M4 Pro Extended Battery Case is perfect for long-term GPS tracking without continuous charging of your Spytec GPS GL300 Tracker. Based on 60-second updates and normal usage, the caseâ€s battery holds up to two-month charge, so you can spend more time tracking and less time charging.
Weatherproof, crushproof, and impervious to dust and liquids, the M4 can be submerged under one meter of water for up to 30 minutes, (in accordance with IP67 testing parameters) so you can track whatever you need wherever it is.
Featuring industrial-strength magnets, the M4 securely anchors your tracker to the underside of any vehicle or metal surface.
Measuring less than six inches long, the M4 Pro Case is discrete and covert.
Specifically designed for use with the GL300 (sold separately), the M4 Pro Case and does not require any modifications to connect with the unit.
