Pros :
- A nice device for reaching somewhere danger / dirty / not accessible, like the box culvert / pipework. For construction works, all new built pipework are required to do the CCTV inspection, as well as for those pipes required to be abandoned, this is a powerful device to enhancing safety and efficiency.
- Also, this device can go to some danger area like somewhere on fire, to let the firefighter knows clearly the situation inside.
Cons :
- None at all, great hunt.
