Regardless, if you are in a region using 2 or more walkie-talkies operating on unlicensed bands, they will still function. Typically walkie-talkies include a channel selector for selecting a pre-agreed channel to operate on. This selector is either a button or dial. It is important to agree on a channel to use before splitting up your group and using the walkie-talkies. Some walkie talkies also include an AM/FM radio scanner, allowing the operator to quickly find and tune into a local radio station. Some even include NOAA weather radio receivers. | Regardless, if you are in a region using 2 or more walkie-talkies operating on unlicensed bands, they will still function.

When selecting a walkie-talkie it is good to ensure it has a high IPX water rating, a 'squelch' function (allows for 'cleaning' up a noisy signal to hear it better, good battery life and has at least 3W of power. Importantly, some walkie-talkies can only be charged in a special charging dock, and so if you choose a walkie-talkie of this sort it is important that it has removable batteries such that you can bring pre-charged batteries with you. If not, it is good to get walkie-talkies that take AA batteries, that you can recharge in a standard battery charger, one of which may include a portable solar charger. | When selecting a walkie-talkie it is good to ensure it has a high IPX water rating, is durable, has a 'squelch' function (allows for 'cleaning' up a noisy signal to hear it better), good battery life and has at least 3W of power.
