First, as a surfer from southern California, I relate to the hesitation to enter hazardous waters. White sharks are a danger and an unmitigated kind of danger. I own a SharkBanz device which emits an electric signal deterring most sharks from an approach and attack. Yet this device is inconsequential on white sharks due to their hunting pattern which involves attacking from deeper waters at high speed, i.e. due to their ambush predation. Interestingly, the SharkBanz device originates from Australia, on the western coast of which are numerous white shark attacks. Of course, it doesn't help that the white shark is a protected species that is necessary to the ecosystem for "balance" according to the fishery experts, who, I might add, have the gall to discuss the benefits of white sharks on shows about their victims. Perhaps lifting the ban and increasing the technological edge could put us ocean-goers in a more advantageous position.

Yes, every time you are in the water. I know from observations that like me you are a fisherman. Whenever you have a lure in the water you can catch a fish but you never catch a fish out of the drink. Fish are predators and react using lateral lines as well as the other senses. It is possible the water clarity may play a roll in an attack so you could maybe reduce the odds when things are a bit more stirred up. They eat and swim and eat and try not to get eaten.Minnesota Nothern Pike or Muskies have been know to die when a smaller pike locks on the head of a larger pike and
It's curtains for both. https://www.google.com/imgres?imgurl=...
Regarding the talking heads on tv the time to question what they tell you is when they open their mouths.
If I kill a fish I eat it .If a shark kills me I would hope he would eat me dead is dead after all.
