Casio has gone tough in the US with Verizon, launching a new Push to Talk  (PTT) handset geared towards those who like to beat their handset while they work.

Coming with "Military standard" ruggedness - a real term - the handset made by Casio will be called the Casio G'zOne Brigade and offer users a flip out QWERTY keyboard in a clamshell design, a 3.2-megapixel cameras and 3G connectivity.

That military standard (MIL-STD-810F) means you get water, shock, dust, vibration, humidity, salt fog, altitude, high temperature, low temperature and solar radiation resistance.

More appealing to small businesses will be Verizon's contacts feature that allows you to manage contacts on up to 50 handsets at the touch of the button, meaning your army of workers never have the excuse of not having the right number.

Keeping on the business front you will also be able to view Microsoft Word, Excel, and PowerPoint presentations as well as PDFs

Yet to be priced the handset is expected out in the US shortly.

Verizon also launched the Samsung Convoy, a more traditional clamshell rugged Push to Talk (PTT) device with military specifications. The Convoy will be available on 15 November.
