Abstract: An automatic fishing device for pulling the fishing line upon fish strike to set the hook. It embodies a trigger member, a weight member, a trigger support, a fish line and a connector for attaching the weight member to the fishing line. The trigger member includes a weight support element and a fish line coupler. Parts of the weight support element can support the weight member but other parts of weight support element cannot support the weight member. The weight member can be connected to the fish line by the connector. The movement of fishing line caused by a fish strike rotates the trigger member to unload the initially supported weight member to drag the fishing line downward, effectively tightening the fishing line for setting the hook.
