IP ratings explained
Ingress Protection (IP) ratings measure how resistant a device is against DUST and WATER.
IP ratings usually have two numbers:
How RESISTANT DOES TWO-WAY RADIOS NEED TO BE?
Radios with a very low level of water resistance, capable of resisting splashes of water. For users who want peace of mind but are not likely to use their radio outside very often.
Radios which can be fully immersed in water, suitable for any level of exposure to liquids including splashes, rainfall, jets and even significant periods completely underwater.
Radios which can withstand light or heavy rain. For users who need to use their walkie-talkie outside but are not likely to encounter bodies of water the radio could potentially fall into.
Radios programmed to use additional frequencies at sea. Often waterproof but only necessary for use on boats and other sea craft.
