Notes on rescue equipment and technology
Plain-language write-ups on the tools used in technical rescue — how they work, where they fall short, and what changed in recent years.

Microbolometers, gain modes and the classic mistakes: reading glass as a window, and water as a wall.
-
Drones in search and rescue: what works and what doesn't
Thermal payloads, search patterns, battery maths and the reasons a drone rarely replaces boots on the ground.

Rope rescue systems: mechanical advantage without the myths
Why a 3:1 is rarely a real 3:1, how two-rope systems are built, and what the "whistle test" is for.
