No, the FoxPro Patriot Digital Caller is not waterproof. We say it is splash proof. If you are caught in a light rain, there is little need to worry. If you need to use the caller in a driving rain, it is best to place it into a plastic zip lock "baggy" to keep out the rain. This has virtually no effect on the sound or volume. If the caller gets very wet, wipe it off as soon as you can. You should also unscrew the speaker to dry out any water that gets inside the caller.
