I often get asked about my CAT S61 phone, so here's a oneyear review.
The CAT S61 is an industrial phone. It's designed to withstand a harsh work environment and has features aimed specifically at engineering and construction. In a way it's a flagship phone, but more in a blue collar than a fashionista sense.

Besides the water and impact resilience it has a Flir Lepton thermal imaging camera, an air quality monitor that reacts to VOCs (Volatile Organic Compounds) like solvents, and a simple laser assisted measuring system that works in conjunction with the camera to estimate distances.
I've been using this for a year, and although the firmware has been a slightly rough ride it has done its job well.
I know you can get plugin thermal cameras, but have always felt that plugging solid items into the tiny charge connector on most phones runs the risk of damaging the connector if dropped.

The only niggle I have is that the main camera drops clumps of frames when used with other apps. That results in sudden jerks in the video. The supplied app is OK for general filming, but for YouTube stuff you really need to be able to lock things like exposure, focus and white balance, especially when doing bench style videos.

When I got this phone it was the most expensive one I'd ever bought. Although initially disappointed by the camera app compatibility issue (tried with and without AP2) it's still become a very useful daily carry phone. Especially with the built in thermal imaging camera. I'd actually feel a bit lost without it.

This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.
