We’ve been featuring water resistant smartphones here but the CAT S50 might just be the best rugged smartphone in the world with military grade protection against the elements.

Aside from being waterproof, impact resistant, dust proof and withstanding extreme temperatures, the CAT S50 also flaunts a 4.7-inch HD display and runs on a 1.2GHz Snapdragon 400 chip with 2GB RAM, 4G LTE access and pure Android 4.4 Kitkat OS!

By the way, we’re talking about Caterpillar – the company that makes tractors, loaders and other heavy machines as well as boots, helmets and other protective gears.

The CAT S50 is certified with the usual IP67 for resistance against water and dust. It is also a certified MIL-810G device which means it can withstand almost anything that you throw at it.

As CAT Phones puts it, the CAT S50 is a “flagship handset designed for outdoor sports enthusiasts and workers who demand both high-end performance and protection from the elements.”


A shock absorbent rubber encases each CAT S50 and a layer of Corning Gorilla Glass 3 makes its screen shatterproof! The touch screen also works even with a wet finger.

The CAT S50 also has an 8MP autofocus rear camera for snapping photos, good outdoor sound quality, 8GB onboard storage with a slot for a 64GB microSD card and up to 16 hours of up time.

There’s also a pre-installed CAT App Store which features hand-picked apps relevant to someone who’ll likely buy the CAT S50.

It is available in forest and slate colors for $499 or around ₱22,000 – not bad if you need a high end smartphone in a harsh environment.
