A very simple rescue tool.
It assists to contact in difficult access situations. It enables a reach contact to be achieved. It saves time & reduces risk as the alternative maybe to put someone in the water to make contact.
It could be the element that makes the difference between a successful outcome or having to abandon a rescue.
The Krab Stick simply converts a karabiner into a hook by wedging in the gate. On contact the force applied releases the Krab Stick thus closing the gate & securing the contact.
