Seek Thermal

Thermal-imaging devices are a hot subject these days. Problem is, some can set a hunter back $3,000 or so. But Seek Thermal's XR smartphone-compatible thermal camera (used in conjunction with a proprietary app) can help anyone track and find a wounded animal after last light for a tenth of the price of some other units. The camera itself is hardly bigger than a box of matches, and when needed it quickly attaches to an iOS or Android phone via the charging slot. SRP: $299. (thermal.com)
