This gadget here is called the Discover GPS Speaker Microphone. Now what would we use a GPS device with built-in speaker for?
EF Johnson Technologies had a smart idea of building this handheld device with GPS functionalities and the possibility to communicate with the other members of your team via the speakerphone.
It can transmit and receive location information, text messages when you can’t speak because others would hear you, an tracking details for the others in your team.
The applicability is clearly undercover field missions.

Specifications include a 120 x 160-pixel monochrome LCD display with backlight, Push To Talk, support for both analog and digital channels, compatibility with the EFJohnson 5100 ES P25 portable radios, transmission encryption, as well as dust- and water-proof design.

Discover GPS Speaker Microphone shows and records location, temperature, altitude, direction of travel, speed and even estimated time of arrival.

"Our new GPS offering is more than just an accessory - it is a complete GPS location solution,” said Michael Jalbert, president and chief executive officer of EF Johnson Technologies. “ The real time location of personnel can be transmitted to other group members or back to a central location. This data can be used in conjunction with compatible mapping and tracking software to provide new information beneficial for maximum efficiency and safety of personnel.”
