- Large buildings or exterior scanning
The FLIR One Pro excels in interpretable imaging thanks to FLIR’s MSX technology, which overlays crisp edge detail onto thermal images. This makes it much easier to identify:
- Electrical components
- Structural features
- Pipes and ducts
- Machinery outlines
Both support video recording, multiple palettes, temperature measurements, and high/low alerts.
🧰 Build and Design
The FLIR One Pro is rugged and features an adjustable-height connector (USB-C or Lightning), allowing use with protective phone cases. It also has its own internal battery, so it doesn’t drain your phone.
The Seek Compact Pro is extremely compact and lightweight, weighing less than half of the FLIR. The manual focus ring allows sharp imaging at various ranges — a major advantage for precision work.
Both are pocket-sized, durable, and field-ready.
