The B3 model is exclusively aimed at those filming with mobile devices with Lightning input using stabilisers or "selfie" sticks. The system is dedicated to Apple brand users (iPhone, iPad). The receiver and transmitter pair up easily only once, using the digital frequency (2.4 GHz) The systems range is 50 metres in free space between the receiver and transmitter. The components of the kit are compact devices that do not weigh down a smartphone or tablet, adding to the aesthetics in the design. The receiver ( RXDI ) is the smallest and lightest component of wireless systems produced on the global market. In size, it resembles an adult-sized finger and weighs just 11 grams. The RXDI is equipped with a certified Apple-branded input - the Lightning connector. The systems transmitter ( TX) has a built-in microphone with volume control on the side panel.
