A global positioning system (GPS) walkie talkie provides added functionality and versatility to the familiar uses of remote two-way communication. Using a GPS walkie talkie can not only keep the user in verbal contact with others, it also can help the user map out routes, locations, waypoints and destinations. Many models and variations are available, but typical GPS information consists of compass headings, current locations, speed, estimated travel time and even popular routes. Using downloaded maps, users are able to plot their own courses, speak to their companions miles away, transmit their exact location like a locator beacon and even speak to other radio users. Choosing the right device is a matter of understanding distance and power needs, field conditions, ease of portability and channel system requirements for your personal or organizational needs.
You can use a walkie talkie for numerous purposes, and your choice of a GPS walkie talkie should reflect your specific needs. Whether you are an outdoor enthusiast, game specialist, government worker or simply enjoy outdoor adventure in rural and urban environments, there is a device for you. The first consideration then is whether you intend to use the gadget for personal hobby, commercial or official use. Knowing the required distance capability allows a choice of the number of channels the GPS walkie talkie will be able to use. Keep in mind that some uses of walkie talkies might require a license from the government where you live.
It's important to determine the degree of accuracy of the GPS walkie talkie. Different models might include access to different varieties of maps which will affect your experience as the user. For some users, pointers to common public trails will suffice, and for others, precise land measurements might provide vital data. Further, the size, weight and heft of the unit might come into increasing relevance with time and distance traversed. How a unit feels in the store might differ from the way it feels after you spend hours or days carrying the device in the field.
You should choose the GPS walkie talkie that offers the best balance in individual performance and ergonomics. Consider whether you need a common water-resistant model or a fully waterproof model. Determine the number of waypoints the unit can access and whether they point to the next waypoints. Finally, combining a GPS and two-way radio saves the money of having to buy separate devices.
