Walkie-talkies have been the standard form of group communication for decades, but the 'Onyx' is a device that looks to help modernize the technology to make it more tech-friendly.
Instead of using a built-in radio connection, the 'Onyx' connects to your smartphone and uses a free app to connect with your team members. Rather than requiring conference calls or group chats to be utilized for group communication, the 'Onyx' allows everyone to stay connected in a constant manner.
The 'Onyx' can be clipped onto your clothing and works like a traditional walkie-talkie except with a series of modern connectivity functions. It uses your smartphone's data to send communications and will work with limitless range in comparison to walkie-talkies that only work within a certain area.
