Interview with Lyndsay Lyon from Ocean Guardian Today's interview is with Lyndsay Lyon from Ocean Guardian, originally and probably better known as SharkShield! They make a range of products that are designed to make ocean activities safer and to decrease the amount of shark attacks on humans. It works by creating an electrical field that surrounds the diver or surfer that causes a distinct and noticeable reaction in certain types of sharks (namely the ones we humans have trouble with, Great White, Bull Shark, Tiger Shark) and causes them to turn away. Now, making a product that aims to stop shark attacks is a big claim and needs to be backed up by solid evidence and rigorous testing. We had a ton of questions from our community asking the questions that everyone wants to know: Will this stop a Great White from biting me? How close do the sharks need to get for these products to work? Can I trust my life to this? If you are wondering at all about any of these questions, have a listen to this episode and it will answer all these and more! In the links below are several videos of these products being tested and you can see for yourself just how effective they are. Important times: 00:14 Intro 05:00 Hello Lyndsay!
