Summary: 

A large scale pinger trial was conducted and results showed a 49% decrease dolphin depredation rates when pingers were active. However the different pinger brands tried were not equally effective in reducing depredation. The AQUAmark 210 pingers had significant results, while Dukane Netmark 1000 and SaveWave Dolphinsaver High-impact did not have significant results. Profit per unit increased 9%.
