Advantages and disadvantages of using GPS trackers with metal and plastic shell

When purchasing GPS trackers, it is common to see that some suppliers provide devices with plastic shells and metal shells. Some customers can’t help wondering what is the difference between these two kinds of GPS trackers, and which is better and which is worse?


In general, the GPS tracker with metal shell is wear-resistant, heat-resistant and flame-retardan, and its external antenna signal is good, but the device is relatively heavy, which will increase the transportation cost. While the GPS tracker with plastic shell is cold resistant, small in size, light in weight, and well sealed, but easily deformed at high temperatures.


GPS tracker with metal shell, for metal shielding signal reason, can only use external antenna to acquire strong signal, which virtually increased the cost of the product for adding the extra accessories, and because of the metal material is relatively heavier, the international transport cost is higher, but in the high temperature regions, the users had to compromise the cost, and choose the heat-resisting and flame-retardant metal shell in case the device is deformed by high temperature.

If the signal and the ambient temperature are stable, there is no difference in the function and operation between these two kinds of device. Most of users would prefer the GPS tracker with plastic shell, not only because it can be hidden well in vehicle, but also can save much cost in accessories and freight. In addition, the plastic shell can be made waterproof and used in some projects that need it to be placed exposed.


Again, it depends on where your device needs to be used to select the appropriate one based on the characteristics of the shell materials, or you can ask the supplier to recommend the best GPS tracker for you.
