How NOCATCH works
A wave-powered green light that clips onto fishing nets.
Meet the light
It clips onto the net line with a screw cap at each end. The lens points out so turtles, sharks and rays see the net in time.
1
Waves power it
A magnet slides through a coil every time the net moves. No battery.
Waves rock the deviceClipped to the net, it never stops moving

It blinks with the sea
Each wave charges it up, and the light flashes green.
Each wave makes a pulse of electricityfirst one way, then the other

Turtles see the net
They swim around it. Fish don't react, so the catch stays the same.
