Usable, with no restrictions.

People follow each other on the road all the time, whether it’s just down the street or halfway across the country. If you’re just following someone to a local restaurant, you probably don’t need to be in constant contact. However, if you’re following someone on a long road trip, having a set of two-way radios can definitely help.

However, most people don’t just have a set of two-way radios on hand. You’ll probably have to pick up a pair before your big trip. If you haven’t purchased two-way radios before, there are probably some things you should look out for when making the big purchase.

Two-way radios can get expensive in a hurry if you’re not careful, so the first thing you’ll want to do is try and shop online at websites like Pebble.com. Heading to your local electronics store may be quicker than ordering products online, but you can save as much as 60 percent on the price of two-way radios just by shopping online.

Also, when looking for two-way radios, you’re going to want to make sure your radios have maximum distance. Most standard two-way radios will reach up to about two miles, which should be a fine distance between you and your convoy counterpart.

Another thing you want to make sure your two-way radios have is multiple channels. It’s likely that there are going to be other people on the road, especially truckers, that are using certain frequencies. You want to make sure you can adjust the channel or the frequency on your two-way radios, so your conversation isn’t met with interference.

Obtaining a pair of two-way radios can be a definite benefit if you’re taking a cross-country trip. You’ll be able to stay in constant communication with the people in your convoy, allowing you to make pit stops together and plan for the trip ahead.

Since so many people have cell phones, you may wonder why two-way radios have not disappeared from the shelves of electronics stores. The truth is that even in an age where portable communication has gone high tech, less recent innovations such as two way radios can be quite useful in certain situations.

These hand-held, wireless communication devices, known in bygone days as walkie-talkies, often work well in environments where cell phones do not. Two-way radios do not depend on the proximity of a cell phone tower to facilitate a signal. Thus, many outdoor recreationists rely on radio communication in remote terrain where there is either no cell tower or cellular signals are blocked by rocky outcroppings.

Families that are traveling in two or more vehicles, or people who caravan on long-range treks, can more easily use two-way radios to keep in touch. To operate a radio, all you need to do is press the talk button, and others whose radios are set to the same frequency can reply in the same way, allowing you to keep your eyes on the road.

The more obvious advantage to using radio communication over cell phones is that once you have purchased the units, you pay nothing additional for unlimited use.

One drawback of two-way radios is that these units are limited in their reach. Many have a range between 30 and 35 miles under optimum conditions. Another concern is that any radios tuned to the same frequency allow strangers to listen in or over-talk your communications. However, most two-way units offer many frequencies, so this problem has a simple solution: just have everyone in your communication network switch to another frequency.

Some two way radios have more features that add value to the devices. You can set your radio to emit an SOS signal in case of emergencies so that others can find you. Some radios have different animal calls you can select as your signature signal when calling another radio. If you are in a situation where silence is essential, such as in a hunting blind, you can set your radio to vibrate should another person call you at an inconvenient time.
