See The 10 Best Walkie Talkies on Ezvid Wiki ►►
Fact #1. The biggest advantage that walkie talkies have over cell phones is that they do not require a cellular network. They have a range anywhere from 20 to 50 miles. So as long as two units are within range of each other, they can communicate together for no cost at all.
Fact #2. They are two-way radio transceivers. When you talk into one, your words are converted into radio waves and sent out. Anyone who is tuned to the same frequency will be able to instantaneously hear it. The main drawback is that that only one person can talk at a time. That is why people say "over" when they finish talking.
Fact #3. These are an ideal way to stay in touch with all the members of your party if you enjoy hiking or camping. People tend to hike or climb at their own pace, and in the wilderness there's an increased chance of getting lost. Plus, there is rarely cell phone service out in the woods. You can be in constant contact, while also allowing whoever is in front to provide updates of what to look out for on the path ahead.
Fact #4. If you need to stay in touch with your employees across a work site, these are the most reliable way to do so. Almost everyone has dealt with the frustration of trying to communicate an urgent message via phone or text. Arming employees with one alleviates that issue, while also allowing everyone in the group to stay on top of what's being said.
Fact #5. Walkie talkies were originally used by the U.S. Military during World War 2 for communication. The first radio transceiver to be widely nicknamed "Walkie-Talkie" was the backpacked SCR-300. It was created by an engineering team in 1940 at the Galvin Manufacturing Company. This company eventually became Motorola.
