This is our flagship product and a game-changer in tracking systems because of its unique features.

It is a compact, waterproof, wearable tracking device which will work anywhere in the world, because you put your own SIM card in it, and it is the only device of its kind specifically designed for 3G bandwidth (which includes 2G/GSM).

The Sentinel ST1 Tracker can be used in water. It can auto-start. It will keep signalling to get successful satellite capture. If cell reception isn’t good, it will store up your position data and send it as soon as possible–no data gaps.


LX Group will be developing the ST1 tracking device.

ST1 can be used whenever other smart devices are not practical or not permitted.
