Show Notes

Lindsay Lyon is the CEO  of Ocean Guardian, a company that manufactures shark

deterrents! Can you really put a device on your surfboard or attached to your leg that will

stop a 15 foot Great White Shark from attacking you? Ocean Guardian claims to do just that

and have the evidence to prove it works! He has a small company down in Western Australia

where they manufacture a whole range of shark deterrent devices: for surfboards,

spearfishing and diving, boating and angling. In 2018 they changed their name in Ocean

Guardian to make a name that would stand out and prove itself to be trustworthy. There is a

ton of great footage HERE of the Ocean Guardian in action! They also have plans to make

the world's first electric shark barrier to make sharky beaches safer to swim in, protecting

humans and sharks! Ocean Guardian products are designed to reduce the risk of shark

attacks, letting you enjoy the ocean without fear.
