The EdgeTech 5112 Ropeless Fishing System was developed to eliminate vertical lines connecting a surface buoy to bottom fishing gear prior to retrieval. Using a reliable acoustic command and control system the 5112 can be deployed “like another lobster trap” but without the need for a surface rope and buoy. This specific system was designed from the ground up with the input of lobster fishermen with the intent of alleviating possible whale entanglement and other negative effects of seafloor-to-surface lines.
