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. 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.

==== 2-way communication guide ==== | |||
If you are needing to split up your group, pre-arrange a signals plan such that groups are not burning through batteries waiting for status updates throughout the period you are apart. That signals plan involves both agreeing on a channel and times or time-windows to be in contact. If the time is known to both parties throughout, specific times or windows of time can be agreed in advance. For instance, on a day long expedition beginning in the morning the expedition party may agree to send status updates at 10:30, noon, 14:30 and between 16:00 and 18:00 as expected range of arrival time. If clocks are not at hand for both parties, sun position will need to be used. | |||
In the event there is a basecamp or base with more than 1 other party working remotely, then all contact should go through basecamp rather than between parties directly. Important information is best written down first for clarity, and to minimise time spent using the handsets so preserving battery life. | |||
The ''RSVP'' guide for 2-way communication is good to adhere to. | |||
* '''R'''hythm - Speak at an even pace | |||
* '''S'''peed - Talk slowly | |||
* '''V'''olume - Speak softly | |||
* '''P'''itch - Speak at a higher pitch than normal and use the phonetic alphabet when spelling out names | |||
