Most inexpensive waterproof radios you’ll find are actually splash proof, or “water resistant.” There’s nothing wrong with that as long as you understand the limitations. I mention it because when I’m reading waterproof portable radios reviews I see a fair amount of negative reviews based on the fact that a given radio won’t survive a direct stream of water, say from a shower head. They are fine, however, with light splashing in the shower or outside in a very light rain.
If you want a true waterproof portable radio, you need to be prepared to spend quite a bit more money than you would on the cheaper “water resistant” radios. The way to tell if a radio is truly water proof is to look for an IPxx, JIS, or NEMA rating. For example, here is a list of JIS ratings and what waterproofing level they correspond to:
- JIS 0 – no special degree of water protection
- JIS 1 – resistant to vertically dropping water
- JIS 2 – resistant to dripping water at an angle of up to 15 degrees from vertical
- JIS 3 – resistant to falling rain at an angle of up to 60 degrees
- JIS 4 – resistant to splashing water from any direction (“splash resistant”)
- JIS 5 – resistant to direct jetting water (“jet resistant”)
- JIS 6 – sealed against direct jetting water (“watertight”)
- JIS 7 – sealed against immersion at a depth of 1 meter for 30 minutes (“submersible”)
- JIS 8 – sealed against continuous submersion under pressure specified by the manufacturer (“submersible plus”)
It should be noted that the rain and splash protection provided by JIS 3 and JIS 4 are much greater than that provided by most of the less expensive waterproof portable radios you’ll find for sale. Unless rated otherwise, assume these less expensive radios fall somewhere between JIS 0 and JIS 1.
