Crew Chief - H42 Spotter Headset and Rugged Handheld Radio Package is tailor-made for Crew Chiefs and spotters focusing on clear communications for NASCAR and IMSA circle track and road racing crew chiefs and spotters. The product pairs H42 headset with a handheld radio. The digital 16-channel RDH is an excellent choice for ultra-clear communication. Alternatively, there's the popular dual band R1 offering both digital and analog operation. For sound clarity and reliability, RDH16 with digital technology for ultra-clear communication is recommended. Being digital, it still allows analog mode for compatibility with standard analog radios. The R1 offers UHF and VHF operation. You can choose from three kit options: Single Radio, Dual Radio and Single Radio with Nitro Bee X. Features include an easy setup, a headset volume knob, a dynamic noise cancelling mic, UHF and VHF operation, radio accessories, and a button lock. The package includes an RDH16 UHF or R1 Dual Band Digital/Analog Handheld Radio, an H42 Behind the Head Headset, a Radio-to-Headset Coil Cord. The radio works with all VHF/UHF business band radios operating on the same frequencies, as well as digital radios using the DMR platform.
