Short answer: the TS004 Pro ($899) is the one to buy if you look beyond 100 yards: 384×288 instead of 256×192 and a 19 mm lens instead of 13 mm. The TS004 ($409.99 on sale) is the right call for the yard and the barn, with an even longer 11-hour battery. Both have a 1-year warranty.

What the numbers mean

Same family, same body logic: built-in 5,000 mAh battery, IP67, 32 GB, 800×600 OLED, five palettes and 1x to 8x zoom. The Pro has 2.25 times the pixels and a longer lens, so by our formula it reaches about 46% farther (950 m against 650 m) and shows more detail at every distance. TOPDON's own figures follow the same logic: 650 yd against 450 yd to detect a person.

The price nearly doubles, though, and at $899 the Pro meets stiffer competition: the RIX Pocket K3 at $799 on sale has the same sensor class with a 5-year warranty. The TS004 has no direct rival at $409.99; it is the cheapest thermal we compare.
