Do I have to leave the Ocean Guardian (Shark Shield) switched on all the time?

Yes, when in the water you should have your Ocean Guardian turned on all the time.




According to the International Shark Attack File of the Ichthyology Department of the Florida Museum of Natural History (see, 52.3% of shark attack victims did not see the shark prior to attack.




Therefore, do not wait to turn the unit on, like all predators, surprise is a key success factor in a attack which is why sprays etc. are of little to no benefit.




Ensure the unit is turned off when you are exiting the water. However, the unit must be switched off when inside a shark cage or in any other confined areas such as wrecks or caves. Also see “When should I turn on the Ocean Guardian.”
