Walkie Talkies are 2-way radios/communicator that present a great way to keep in constant touch with members of your party, whether on an outdoor adventure, vacation, road trip or at a crowded shopping mall or amusement park. With the ability to talk, hear and ring other radios within range, they are a lot like having a short-range cell phone - except without the usage fees and contracts. This wrist watch style radio allows communication with an amazing range up to 1.5 Miles in clear outdoor setting. Or, for indoors, it can also be used like a wireless intercom in and around the home to call someone out in the yard or on the far side of the house. For business, this radio can be used within offices or warehouses for easy communication between staffs. The Omnizel EZ-Talk series includes a rare feature of 38 Group CTCSS Sub Codes for obtaining clear signals in over 800 ways. Omnizel also includes a better and more reliable 3.7V Lithium-Ion rechargeable battery with a standard AC charger included. This radio will work with ANY OTHER compatible standard FRS radios/devices.
