Their new HI-5 hand unit is a follow-up to their iconic WCU-4 (which has officially been discontinued) and looks to have improved on every aspect from the previous model. Let’s take a look at what you can expect to find with the new HI-5 Hand Unit. 

Right out of the gate, the look and design of this new system are extremely ergonomical, sturdy, and was clearly built with focus pullers' actual needs in mind.

With everything that can and will go wrong on a film set, one of the few aspects that should be a seamless process is focus pulling. An already stressful job can prove to be even more stressful with faulty equipment, which is where the new HI-5 Hand Unit hopes to be your be-all-end-all solution to frequency issues, un-user friendly interfaces, and a personalized experience for anyone who uses it.

With the HI-5, perhaps the most impressive aspect of this new release is the inclusion of three swappable radio modules, the RF-EMIP, the RF-2400, and the RF-900 for different regions and frequency regulations and shooting situations.

So no matter where you are or how clear the frequency is you’re working with, having these separate modules will ensure a smooth shoot.

Together, they cover a multitude of shooting situations with a significantly improved, robust, and long-range radio link, while ensuring backwards compatibility with existing camera equipment. As technology evolves, even more modules can be added, making the Hi-5 a future-proof investment, able to accommodate future standards for on-set hardware communications.”
