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. 

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 modules. Added to that, the batteries can be charged via the inbuilt solar panels.  Using inbuilt sensors, the TR55 can detect movement / vibration as well as if the tracker has been removed from the tracked object.

The TR55 operates on 4G and can operate in over 70 countries around the world. It 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.

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. 

How to build your perfect TR55:

  • Select how you want to power or charge your tracker. If you plan to use as a standalone tracker where there is no power supply, select the Charging Module. If you plan to power from a vehicle battery select Wiring Module
  • If you are using a Charging Module, you can extend the battery life by adding a Battery Module. You can add up to two battery modules and each module adds 3x the power of the TR55 base unit.
  • Finally, select your fixings. The TR55 can be screwed or bolted to the item you want to track. Alternatively for speed and ease we offer a Magnet Module which includes high power magnets, fixings and sensor shields to allow fixing to a metal surface.
