I'm a big believer that every toolbox needs at least one thermal camera. They might seem gimmicky, but the ability to see hotspots in vehicles or electronics, or where heat is escaping your home (or drafts leaking in!) can be an invaluable when diagnosing issues.

Problem is, a lot of thermal cameras are expensive, and they are often specific to either iPhone or Android, so if you switch platforms, you'll need a different camera. The new Thermal Master P1 solves both these issues with an affordable thermal camera that works for both platforms.
The tech specs for this unit are strong: the camera has a native resolution of 160 × 120 pixels with a 25Hz refresh rate that's upscaled to 320 × 240 by Thermal Master's proprietary X³ algorithm to offer pin-sharp images. The camera has a range of -4°F to 1,112°F (-20°C to 600°C) and an accuracy of ±3.6°F, making it perfect for a wide range of applications, from insulation inspections and HVAC system diagnostics, to automotive troubleshooting.
While the camera features a USB-C port,allowing it to work with Android smartphones and the latest iPhones, I've tested it on an older Lightning iPhone with an adapter and it works fine.

The P1 is super small and super light, measuring 2.32 × 1.06 × 0.68 inches (59 × 27 × 17.2 mm) and weighing only 0.62 oz (17 g), so you can attach it to your phone and it doesn't add much in the way of bulk or weight.

That lightness is double-edged. As thermal cameras go, this one feels plasticky and cheap in the hand, and I doubt it would take too much abuse or exposure to the elements, but this is a camera built to a piece -- a sub-$150 price point at that. Thermal Master have high-specced cameras -- such as the P2 or the P3 -- but these are cameras in the $190 to $300 price range. They have greater accuracy, and are built tougher, but at a price.

The P1 also comes with a zippered protective case, a 50cm extension cable, and a quick start guide to get you up and running (setting up literally consists of downloading the Temp Master app -- iOS and Android -- and plugging the camera in).
ZDNET's buying advice
Yes, there are better thermal cameras that the Thermal Master P1, but I challenge you to find one that's better for the $130 price tag. The ±3.6°F accuracy is great for all but the most high-precision of work, and I've found it to be more than good enough to spot a faulty and overheating capacitor on a circuit board.
This is a great thermal camera for someone who isn't going to be using it every day or taking it out into the field with them. For the $130, this is also perfect for the avid DIYer that wants all the cool gear, but doesn't want to spend hundreds of dollars.
