RugGear, a manufacturer of rugged mobile devices, introduced the RG725, a device as flexible and quick to use as a walkie-talkie but with all the advantages of a smartphone, according to company officials. The product is built with push-to-talk oriented design for industrial users to boost communication and workflow efficiency in a variety of work situations. A large battery and an extra-loud, over-105-decibel front speaker perform well on noisy construction sites, say company officials.
