Turbo Jav practice javelin

Turbo Jav is the implement a coach hands to a child before a real javelin. It is moulded from shock-proof plastic, so it survives being thrown onto grass or tarmac by a group that has not yet learned to land a javelin point first, and it is safe enough for a school field.

The Vortex is catalogued alongside it for the same preparatory stage of javelin teaching.
