Based on our limited time with the Cat S60, we're not too sure whether it'll be poplar with the general public. Its bulky form factor may be off-putting for some, and the addition of a thermal camera may not be enough to persuade a consumer to buy the smartphone - sure it's a cool addition, but we're not completely convinced that it's more than a gimmick. With that being said, if you're in an industry that requires the use of a thermal camera or if you're prone to breaking your smartphone then it's an ideal option. We'll give a more thorough verdict once we get a sample back to the PC Advisor towers!

Owning a smartphone means you're also privy to the very particular fear of dropping that smartphone. And many of us go different lengths to mitigate this problem. Some of us slap our phones in big, fat, protective cases. Others are like me - we lie to ourselves and pretend we'll be fine without one.

Very rugged; Thermal camera is fun and useful; Good standard camera

Mediocre screen; Expensive; Hefty design; Thermal camera app is sluggish

The Cat S60 is thick and hefty with an unapologetically industrial design. In addition to being a tough SOB that can endure 6-foot drops and the most waterproof phone made to date, it also has one thing no other phone possesses: a built-in thermal imaging camera.

The Cat S60's durable build is impressive, but its appeal is limited to those who can make good use of its built-in thermal imaging camera.

The Cat S60 features a built-in thermal imaging camera; It can consistently survive 6 foot drops onto concrete and can take a 16 foot dunking into water; It has an expandable microSD card slot and loud front-facing speakers.

It's significantly thicker and heavier than other smartphones; The thermal imaging feature while cool and fun, is mostly useless aside from some specific cases.

I must admit, I am far from the target customer for the Cat S60 ($599 unlocked), a rough-and-tumble phone made for people like contractors, firefighters and military personnel. After all, I spend most of my workday sitting on an ergonomically padded chair in a climate-controlled building while...

Great battery life; Unique built-in thermal imaging feature; Attractive; durable design; Superbright screen

Mediocre performance; Lackluster low-light photos; No 802.11 ac Wi-Fi

The Cat S60's spec sheet reads more like a superhero's vital statistics on paper, and the military-grade protection, strong angular looks and the ability to identify heat signatures make it a thing of wonder.

Thermal imaging; hard as nails build quality; long-lasting battery; genuinely useful apps

Medium-powered; screen only HD; gimmicky Underwater mode; high price; niche appeal

Most smartphones are too fragile for job sites. They break when they're dropped, or crap out when submerged in water. The Cat S60 is different. It's designed to take a ton of punishment and continue to operate.

The Cat S60 is not for everyone. Without the very clever thermal imaging camera all you're left with is an unspectacular, albeit rugged, phone.

Medium-powered; lowly HD resolution screen; gimmicky Underwater mode; high price; niche appeal

The CAT S60 is one of the most interesting smartphones I've tested this year. Featuring a rugged, near-indestructible chassis, the S60 is the first phone I've seen with a built-in thermal imaging sensor.

It gives you Predator vision; Rugged; close to unbreakable design; Near untouched Android OS

CPU could be faster; Regular camera is slow

Sometimes, one standout feature in a smartphone can help it pull ahead of the crowd and become an almost instant classic. Caterpillar's Cat S60 smartphone almost manages to accomplish that feat thanks to a unique feature, a heat sensor, that transformed it into the world's first thermal imaging...

The S60 really is the smartphone version of Gordon Freeman's HEV suit. It ticks every box that will suit a hard outdoor life, and doesn't seriously skimp out on hardware to make that happen.

Better thermal vision than the Predator; Properly rugged; will survive a real beating; Battery life for days

Won't win any style awards; Overkill for most people; Costs as much as a flagship phone
