Electronic shark repellent

[Jules22]

Hi guys does anyone know if these shark repellents work and if so which ones are best ?? Thanks

I used these when in school for diving on Tangalooma (worst danger there was the wobbies:):)) I turned one off, dove next to one on the bottom and turned it on and it took off quite quickly so I can say they work for the small ones at least. Only annoying thing is if the antenna touches you or anyone else they get a nice zap. This was a few years ago so they may have fixed this.

There is one out, we used it up north, it doesn't work continuously, but intermittently give out a decent blast and anything teethy around would get a warning or sensory override and high tail away.
