No cons




From the first sight you know that this phone is tough: it is constructed with an aluminum-reinforced frame and meets military-grade standards such as Spec 810G rating. And it's also IP68 dust and water resistant, and can survive 1.8-meter drops on concrete.But this phone not just about its super-tough construction: it has three awesome super powers. The first one is a FLIR thermal imaging camera. Additionally, the Cat S61 features an innovative Volatile Organic Compound (VOC) sensor. Last, but not least, the Cat S61 features... lasers! A tiny laser beam comes out of the back of the phone and can measure things of up to 10 meters distance.

    • IP certified:

      IP certified - The IP code indicates the degree of protection against dust and water. The first number represents dust protection, while the second represents water protection. In IP67, for example, 6 means a completely dust-tight device, while 7 means the device can stay immersed in up to 1 meter of water for up to 30 minutes. In IP68, a higher level of water protection is expected, but exact numbers aren't specified: both depth and continuance are specified by the manufacturer on per device basis.

  • Technology:

    Technology - There are two main screen technologies currently used in phones and tablets: LCD and AMOLED. The former usually features a light source and liquid crystals, while the latter is based on organic light-emitting diodes. Newer LCD variations like IPS-LCD and Super-LCD allow for very accurate color reproduction and very wide viewing angles, where no significant image quality loss is observed. Current AMOLED screens differ in such a way that they can exhibit much more saturated colors (sometimes too much) and incredibly high contrast levels, which is due to black color being completely black in AMOLED displays.
