An avid surfer on Cape Cod, Jim Papadonis has seen a great white shark, and all of the surfers he goes out with have also. Read More There was the time he saw one fully breach the water about 150 yards from where he was surfing. There was also the time a friend and fellow surfer had a shark chomp into his board just after he had rode a wave in.
Papadonis, along with the rest of his surfing group, all use shark repellents from Ocean Guardian, particularly one that attaches to their surfboards, he said.
Ocean Guardian devices, according to the company’s website, emit an “electrical field” which affects a shark’s short-range electrical receptors. The electrical field doesn’t harm sharks, and it doesn’t hurt other fish.
“Nobody really claims to be 100 percent effective but our view in this community is every little thing that we do is better than nothing,” Papadonis said.
The nonprofit is also looking at Ocean Guardian’s other technologies, which aren’t currently in use in this area, including one that attaches to a boat and creates a small shark-free swimming area around the vessel using the same electrical field technology the surfboard device does. There’s also a product that could create a larger swimming area with a buoy system.

I have always been fascinated by this. Back in WWII (and probably since then) they had some of the best minds working on it, and...they couldn’t solve it.
How to repel sharks. Seemed like after all that, a bang stick was the only sure way.
And even then.
The tourists probably taste better than the natives.
They should wear little bells. Hey, they repel grizzlies...
There’s a reason why “Charlie don’t surf”.
Orca scent will send the Whites racing for “cover”!
Just kill a few sharks
Put them in underwater cages
Let the smell and blood permeate the water area
Sharks can smell that miles away
Repeat as needed
“Sometimes that shark looks right at ya. Right into your eyes. And the thing about a shark is he’s got lifeless eyes. Black eyes. Like a doll’s eyes. When he comes at ya, he doesn’t even seem to be livin’… ’til he bites ya, and those black eyes roll over white and then… ah then you hear that terrible high-pitched screamin’. The ocean turns red, and despite all your poundin’ and your hollerin’ those sharks come in and… they rip you to pieces.”
Yep orca feed on the livers of white sharks and have learned how to immobilize the whitesharks be flipping them upside down with the orca’s tail- white sharks have learned to skedaddle when they see orcas if possible,
or they think something is killing the sharks in the area- so they scoot- Mythbbusters did a show with dead shark scent- it does work- but only for about 5 minutes unless you keep releasing some when they start to return-
You remember the details far better than I.
Sharks think? Who knew! ;)
OK instinctual reaction to what appears to them be other sharks ‘dying’ around them because of the smell. Animals do have fight or flight instincts, which react to certain situations. Whether thought is j volved or not I don’t know, they do seem capable of making decisions about what to do, but also go into complete purely instinctual reaction at times like during feeding frenzies
a Nancy Pelosi mask.
Hunger is the best sauce, and that may apply to certain sharks who will act differently than we want them to behave. -Tom
Don’t get me wrong, I know virtually nothing about sharks. I merely suppose that when they’re looking for food, they will put just about anything in their mouths. Shark flesh can’t taste that different from non-shark, and anyway, many animals eat their own kind.
What if the shark misinterprets “eau de cadavre” and proclaims “You killed my father! Prepare to die!”
If I had to buy a shark repellent, I think I’d go for a pod of killer whales.
there was a mythbusters show showing how they run for the hills when the scent is released- i dunno if they think or not- but i watched it, and they really took off fast-
yeah in the mythbusters show- they weren’t sure if other sharks would react the same- but speculatd that they would, as the stuff they used was synthetic i guess- and not a specific species of rotting shark-
