The 1W Handheld UHF CB Radio will allow you to communicate between the 2 radios within a 7km range, great if you are 4WDing in a convoy, so you can warn those behind you of upcoming hazards and things to keep an eye on. You can use them as your primary means of communication, or just as a backup if you are out of reach of mobile coverage or if your devices are out of battery. They are also great to have in an emergency situation. If you are hiking or bushwalking within 3km of your campsite, you can radio for help if you have injured yourself. These hand-held radios are easy to use, and the hassle-free channel scan will ensure that you have access to up to 80 different channels, and also a FM radio so you can listen to music. You will love the backlit LCD display, which is perfect for night time conditions. It comes with a USB charger which is great for charging your batteries in your vehicle or caravan. The 1W Handheld UHF CB Radio would be a great addition to your camping, hiking, or boating trip, so you can have peace of mind knowing that help is only a radio call away.
