Due to an increase in shark bite incidents globally, it is becoming increasingly important to develop safe methods of deterring sharks. Here, I investigated the deterrent effect of two commercially available electric deterrents (Shark ShieldTM and ESDS™) and two magnets (ceramic and rare-earth). The Shark ShieldTM proved to be the most effective at deterring sharks, while the presence of the ESDSTM and the two magnets had little effect on shark behaviour. These results emphasise the species specific nature of electrosensory deterrents, and serve to highlight the importance of rigorous scientific testing of commercially available shark deterrent devices.
