Abstract: A fishing diver is provided by a diving plane with a first releasable tripping device having a latched condition clamping the diving plane to the line such that upon trolling, the diver dives downwardly at an angle to the trolling line, and having a released condition unclamping the diving plane from the line. The diver includes a second tripping device associated with and engageable with the releasable first tripping device. The second tripping device has a latched condition engageable with the fishing line, and a released condition responsive to the strike of the fish on the lure for causing the first tripping device to reach its released condition and provides free sliding passage of the line through a guide structure on the diving plane. The fishing diver includes an indexing arrangement for the first and second tripping devices.
