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 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

The Cat S60 tops its next-closest competitor, the Samsung Galaxy S7 Active , in almost every way. It's more durable, has a brighter screen, lasts longer on a charge and looks better. At $599, the S60 is cheaper, too. And that's before you even talk about its built-in thermal camera.

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

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

If you look for the most unique smartphones available in India at the moment, then the CAT S60 has to be right up there. This device does a lot of things, which other smartphones can't even dream about. But is that enough to woo customers, especially when you have a Rs 64,990 price tag

You will never ever worry about what happens to this phone if it takes a fall on the ground, or slips into the pool as you were checking the water's temperature; It is that kind of phone and just the looks of it gives you that kind of confidence, I did take the phone into a pool and could still use...

Perhaps I could say my CAT S60 was cursed or that little gremlins were living inside, but the fact is that one of the reasons I bought the phone, aside from FLIR, was the fact I could dive up to 5 meters in water. This allows me to go freely with my kids and play in water and take some nice videos.

FLIR camera

Does not perform as stated under specifications; Bad camera shots

Really rugged!, may need a little better resolution, but works excellent!

Have had this phone for about a year. A small screen that covers the part that I talk into came off. But that really hasn't impacted its use. It is still waterproof and works fine.

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

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...

One very tough rugged phone; Good performance levels; Built-in FLIR camera

Pretty hefty; Also pretty expensive; Small size of display could be problematic for some

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
