Now that nearly everyone has a cell phone, why does anyone need a walkie-talkie? Well, there are actually many scenarios where walkie-talkies offer an advantage over cell phones.

A walkie-talkie, or two-way radio, can be an essential tool in industries involving on-site coordination—such as construction, warehouse work, security, event planning, and live performance. If you are communicating with multiple people who are spread out around a property, you don’t want to have to set up a conference call or contact each person individually on the phone.

A long-range two-way radio is also useful for more leisurely activities, like exploring the outdoors with friends. In fact, it can be important gear for off-the-grid activities. You might want a set of 2-way radios when rock climbing in areas where communicating visually or verbally is a challenge. If you’re taking your electric bike on a group cycling tour, walkie-talkies can help you all stay in touch as you ride.

To get the most out of your walkie-talkie, start by choosing the best two-way radio for your activities. When shopping, consider the number of channels available and the radio’s range. The more channel options you have, the more you can avoid channels with interference, and long-range 2-way radios can create a powerful signal for many miles. Keep in mind, of course, that certain materials and obstructions can get in the way of transmission and receiving no matter how strong the signal.

You may also want to consider additional features that can help you make the most of your new walkie-talkies. A water-resistant walkie-talkies may be the best walkie-talkie for certain environments, especially if you are choosing a marine radio for use on a boat. Walkie-talkies with built-in GPS can also help you identify the locations of all users more easily.

Finally, ensure you have portable power banks for charging, along with other useful two-way radio accessories.
