Abstract
Abstract An impact messenger for submerged apparatus has an open condition for being placed on a guide wire in a closed condition for downward travel along the guide wire. A spring loaded locking pin locks the device in the closed condition and has an arresting pin portion protected by a shoulder and prevented from slipping off by the inner edge of one fin of two diametrical fins. The fins and grooves in the outer surface of the device facilitate handling and increase the stability and descent speed during the drop.
