Description
Best in class sensitivity ensures crystal-clear communications in fringe areas and harsh environments while a compact form factor means the radio is suitable for a wide range of users.
The SDP750 offers a rich feature set including full-duplex calling, allowing for enhanced communications between office and field staff. Additional features include GPS, long battery life and Bluetooth to allow for the connection of additional wireless accessories.
The radio’s ability to allow the user to operate across a variety of network signature modes means it is not only a safe and future proof investment but also provides a cost-effective and flexible migration path for organisations managing the transition from analogue to DMR digital.
