Digital Camera World Verdict

These days there are a lot of tiny thermal cameras that plug into phones, but Xinfrared has done a good job of making this perfect for wildlife trackers and hunters, while still potentially having use around the home. The mount is a bit odd, but certainly versatile, and a phone-side heat scope helps find animals.

Thermal monoculars are a great way to spot wildlife, whether you're tracking it or hunting it. Traditionally these have come in the form of a monocular or a gunsight, but the X2 is built around a small phone attachment and some accessories you can build to suit you.

Many DIY-ers have discovered the benefits of compact thermal cameras which work as phone attachments. Some are in our best thermal cameras list and their principal benefit for plumbing, motoring, or electronics work is their low cost. Now that price advantage is available for hunters – though Xinfrared has had to solve a few problems, hence the other accessories.
