The first digit always indicates the level of protection from dust ingress, while the latter signifies the level of protection from water. The majority of protected devices on the market right now are only resistant to either of the two elements, and not foolproof, but not the M2 Aqua.
Kyocera Brigadier that we reviewed just recently, is also similarly resistant to the element, so do keep that in mind.For one, its IP6X certification indicates that it is completely dust tight, and the IPX5/X8 part means that it's not only resistant to water jets (projected by a 6.3 mm nozzle), but also waterproof for "over" 30 minutes when submerged in water (up to 1 meter).
