Digital Camera World Verdict

This is a big, heavy-duty tool phone which packs night vision and thermal cameras into a body which will survive some serious violence. At the same time, it manages to compete with premium phones with a decent camera – especially for stills – and fast processor and screen.

This isn't the first Doogee rugged phone we've covered; the brand has established a great reputation producing almost indestructible handsets for what is a very competitive niche in the phone market. One where svelt design gives way to something that can withstand some serious drops.

People looking for the best rugged phone aren't always looking for the absolute top specs (not, of course, that they'd complain). Instead the term "toolphone" is common – a phone considered part of a toolkit while, perhaps, a smarter phone is the daily driver. In other words plenty of contractors want an on-site work phone that can cope with some roughness, and some might also have another handset.

Samsung Galaxy XCover Pro

If you don't need a thermal camera, the Samsung Galaxy XCover Pro is still rugged enough for the MIL-STD-810G spec. It might not match flagship specs (far from it) but it is a trusted brand and lighter, which might be a factor if you're carrying it as a tool phone.

CAT S62 Pro

if you're keen on the thermal camera, but want a smaller handset then the CAT S62 Pro might not be stuffed with the latest features (it dates from 2020), but it does boast a thermal camera from FLIR.
