Ocean Guardian

Ocean Guardian is the manufacturer of Shark Shield shark repellent devices. The Ocean Guardian electronic devices create an electromagnetic field to deter shark attacks and are used by surfers, scuba divers, snorkelers, spearfishers, ocean kayak fishers, swimming areas off boats and for ocean fishing. It is considered one of the few electrical devices on the market that has performed independent trials to determine its effectiveness at deterring shark attacks, Whilst it is noted the Shark Shield technology does not work in all situations, modelling research from Flinders University in 2021 indicated that the proper use of personal electronic deterrents is an effective way to prevent future deaths and injuries, and estimated that these devices could save up to 1063 Australian lives along the coastline over 50 years.
