The Latitude 150 walkie-talkies from Binatone provide free communication over a vast distance of 3 kilometres (1.8 miles). There are 8 transmitting channels to choose from for maximum communication and a scan function allows a search for others using the same channel. An LED display screen indicates the channel being used. The Binatone walkie-talkies sound a confirmation beep to indicate when others are ready to talk. The Latitude 150s have adjustable volume controls and a low battery warning; they also include an LED signal strength indicator. The Binatone walkie-talkies have an ergonomic, compact design featuring a moulded grip and belt clip for ease of use and transport. The Latitude 150 includes a charging dock to reduce the consumption of new batteries.
