Our Take on the Motorola RDU4100 RDX Business Series Two-Way UHF Radio (Black):

There is no denying that with 10 wireless channels, you will get exceptional audio quality. Further, the device possesses Wind noise reduction quality and the speaker magnetic field reduction feature, resulting in unmatchable audio transmission. For a fast-paced environment, you can program it via the in-built CPS that will auto-recognize select serial numbers, frequencies, and features.

These features, along with the water-resistant nature of the device, make it perfect for heavy-duty on-site work. Its die-cast metal chassis gives it its sturdy exterior.
