Observations
- THERMAL MASTER'S FLAGSHIP, ANDROID-ONLY, unlike the already-covered P2 Pro and P3, both of which come in iOS and Android versions. The same NETD as the P3 (35 mK, the best in the range according to the manufacturer's own comparison table), but without the electronics-repair-oriented macro lens that sets the P3 apart.
- A positioning that raises questions. Identical NETD to the P3 but a higher price according to the same comparison table, with no documented technical spec that justifies the gap beyond the lack of iOS compatibility.
- 15× digital zoom, identical to the entire already-covered P2 Pro and P3 range.
