A rugged Android smartphone which can be bought unlocked for
Wi-Fi only synchronization, the Brigadier is a budget friendly option that
will also weather drops, water, and the elements. The Brigadier is one
of the toughest phones on the market with a scratch proof and crack
resistent Sapphire Shield Display and Military Standard 810G protection
against dust, shock, vibration, temperature extremes, low pressure,
solar radiation, salt fog, humidity, blowing rain and water immersion.
