DESC: Boasting an ultra-clear long-distance range of up to 10 miles (depending on terrain and conditions), this pair of Cobra PR 3500-2 DX two-way radios is ideal for adventurous hikers, rescue workers, or even parents who need to keep tabs on their kids from several blocks away. Each radio comes equipped with 22 channels--eight GMRS (General Mobile Radio Service), seven FRS (Family Radio Service), and seven GMRS/FRS combo channels--on which to communicate, in addition to 38 privacy codes. All told, the channels and privacy codes combine to provide 836 "sub-channels," ensuring that conversations are always exclusive even in crowded areas. And should you accidentally lose contact with your group, you can easily scan the possible code combinations to learn which nearby channels are active, or scan for unused channels when the frequencies are packed.
