You must first understand the purpose of using the walkie talkie, such as for leisure / recreational purpose or for commercial purpose.
Leisure walkie talkies are ideal for recreational purposes such as when trekking, cycling or camping. That means you would not require the frequent use of the walkie talkies. You may wish to consider purchasing a license free walkie talkie as the equipment are more affordable.
Commercial walkie talkies have a much broader range for communicating, extending up to 18km. These aren’t intended for hobby use, rather they’re meant for businesses or commercial activity.
You may consider purchase either the Analog or Digital walkie talkie, depending on your budget and type of usage, such as whether could you require text messaging or just plain 2-way group communication.
