HELMER LK 541 4G GPS locator
Reliable tracking for vehicles and valuables
A GPS locator is a compact device for carefully tracking cars, luggage, and other valuables. The HELMER LK 541 combines GPS localisation with GSM/GPRS/LTE mobile connectivity, letting you find its current location via SMS or conveniently online on a map through a web interface or mobile app. You can just as easily view its movement history. The device has a strong built-in magnet, so it can be discreetly attached to any metal surface. The online service itself is completely free for this locator – you only pay for the mobile data on the SIM card used. Data consumption is approximately 30MB per month.
