Abstract: A fish hook setting device having a housing with longitudinal passage, a collet shaft slideably received within the longitudinal passage of the housing, a trigger assembly comprising a trigger rod slideably received within the collet shaft and a collet, and a biasing member engaged with the collet shaft. When the device is in a cocked state, the biasing member is compressed, and when the device is in an un-cocked state, the biasing member is decompressed. When a fish bites on the bait of the hook, the device is triggered from the cocked state to the un-cocked state as the trigger rod and the collet shaft are forced upwards by the biasing member to set the hook into the mouth of the fish.
