with their electrical sensors so it scares the shark away. i grew up in california and surfing was part of life for many of the people and you are right, some of the worst days of weather in the world of the waves are big, they re going out to go surfing. sandra: it was an australian surfer that came up with this back in 2017, involved in three great right shark attacks and even lost a friend to one he got creative and came up with this. what i find interesting about it is they put this out there as well when they re talking about this idea is they say there is no fail-safe to this, nothing you can do that will absolutely guarantee the sharks are going to stay away from you. maybe not surfing with chum but it s an interesting idea and people that want to get injured. 2300 shark sightings. sandra: this is a growing issue. i wouldn t say problem.
