The Bulldog TR55 GPS Tracker is the ultimate in versatility and adaptability and lends itself to virtually any tracking requirement. The modular design means you build a tracker to meet your exacting needs. Want a tracker with over 5 year battery life? No problem. Want a tracker that can charge itself? Of course, the TR55 does that. Want a tracker that can operate in over 55 countries around the world? The TR55 has you covered.

At the heart of the TR55 is a modular design that allows it to be used as a standalone tracker using high powered magnets, if required, for a quick deployment wireless tracking solution. Or for those looking for a hard wired solution in the most demanding situations, simply attach the wiring module and wire into a vehicle power supply.

For those situations where a long battery life is important, the TR55 battery capacity can be increased by 600% by adding on additional battery packs. Added to that, the batteries can be charged via the inbuilt solar panels.  Using inbuilt sensors, the TR35 can detect movement / vibration as well as if the tracker has been removed from the tracked object.

We believe the TR55 is the one of most rugged and durable trackers available and with over 5 years stand by time is hard to match.

The TR55 is fully compatible with our tracking service and can be monitored via our tracking site or through our smart phone app which feature location information and offers push notifications of important events.

The Bulldog TR55 is IP66 rated meaning it can be used in the most demanding environment and is widely used by haulage companies on containers, trailer rental businesses and those looking for a quick deployment tracker that can handle the most demanding conditions.

The TR55 can be used to alert you via our TR03 tracking platform which offers the ability to track and report using a range of variables such as geofencing, speed, travel time, mileage and many more.

As a tracker the TR55 is an exceptional choice and rapid installation allows it to be used in anything from plant and machinery through to tracking shipping containers. In wireless mode, the internal GPS antenna and no external wiring means it can be hidden virtually anywhere on the tracked object.

Unlike almost every other tracker where you need to buy additional wire's, SIM cards, gizmo's or gadgets to get up and running, the Bulldog TR55 has been designed with you in mind and includes everything needed to be tracking in no time.

As with all Bulldog Trackers, we ensure that it is simple to use and provide full and detailed solutions together with our great after care.
