When shopping for GPS speedometers, it's important to think ahead and consider your intended application. These devices are unique because of their ability to draw data from a satellite, eliminating the need for complicated integration with your particular vehicle. Some models will cost more because they're waterproof, such as the Eling 3-3/8", which may not be worth the added cost if you never plan to expose it to the elements. But if you plan to attach this to a motorcycle, boat or off-road vehicle, you definitely want to invest in the added protection.
Charging capability is another key aspect with these devices. Many of the options designed for motorcycles or ATVs, like the Eling 3-3/8", Eling Waterproof 3-3/8" and ATACH 3-3/8" will require hard wiring to the vehicle's existing electrical system, while most of the variations intended for cars will draw power from a USB connector through the built-in cigarette lighter socket. Most of these options include all necessary power cables, but not all. Before purchasing, be sure to inspect your vehicle and figure out which charging style will be most suitable for your needs.
Also, mounting style should a critical feature of your purchase choice. Depending on what type of vehicle you would like to use this instrument with, you may be better off selecting one style over another. This list includes a range of models that are ideal for motorcycles, bicycles, cars and marine applications.
