The Caterpillar B30 is designed to be a tough phone made for whatever life throws at it. The tough outer casing is IP67 certified meaning it can withstand a drop onto concrete from 1.8 metres and it is dustproof and water resistant. These tough phone credentials make this the best phone for builders or for anyone that enjoys outdoor pursuits. The 2-inch display is bright and the keypad makes text creation easy. There is an MP3 player and a FM radio so you can enjoy music when out and about and there is a handy torch on board to help you find your way in the dark.
