TuningEasyCue Lifebuoy, making life-saving equipment usable. Rescue equipment is supposed to save lives, but what happens when it’s too complicated to use in time?

In emergencies, the clock doesn’t tick — it roars. Within five minutes, lives can be lost or saved, and every second spent fumbling with gear is a second too long. The harsh truth? Most traditional rescue tools take around three minutes just to deploy. They’re heavy. They’re confusing. And unless you’re trained, they’re nearly useless.

Developed with one clear mission, make rescue intuitive, TCE throws out the rulebook on overengineered life-saving gear. Instead of complexity, it’s built on instinct. No levers, no latches, no guesswork. Just grab, throw, and spin — and you’re already in action. The core idea behind TCE is simple: in high-stress moments, people don’t think, they react. So the equipment must match that reflex.

TuningEasyCue uses a natural, throwing-based motion that people instinctively understand. No tutorials needed. No strength required. In tests, it performed in under half the time of traditional rescue tools — without compromising effectiveness. TCE requires just 25% of the effort needed for existing equipment, that means children, seniors, or anyone under pressure can use it, and use it well.
