Why do you choose Radioddity GD-77S?
GD-77S is a series product of GD-77. "S" stands for "Standard". Without LCD screen, the newly added button makes it easy to switch between channels, and the voice prompt function helps you know all the frequency details. We also pre-programmed the channels of GMRS/PMR446 in the CPS so you can choose and easily use those frequencies. All these are to make a "standard" and easy operation radio which can turn on and use directly.
Up to 5KM (3 Miles) Talking Range
Although GD-77S is only 3CM in body thickness, the talking range can be as far as 5KM (3 Miles) under most circumstances. There are other factors that affect the range of a two-way radio too such as weather, exact frequency used, and obstructions.
