Non organic ways to attract sharks

" The two scientist discovered that when they pulsed very low frequency sounds below 60 hertz in a rapid but irregular pattern, The sounds consistently attracted sharks such as bulls, tigers, lemons,and hammerheads."......................."Experiments in the ocean ocean have shown that randomly pulsed low frequency sounds can attract sharks from as far away as four hundred yards or about a quarter mile. "

Pg 111 " The Shark Chronicles" John A Musick and Beverly McMillan

This method sounds great, Multi directional "E-chumming" that places like Hawaii where shark chumming is now illegal can use to still attract these animals.

Here is the Idive300 its meant to play the ipod underwater to depths of 300'. The speakers are pretty loud, Put it in some steal cage as protection, and here come the sharks

Has any one tired non-organic methods? I've heard about crunching water bottles , but have had no luck

I doubt those puny little speakers could put out

The water bottle trick usually works if the sharks (or jacks, or groupers) are already relatively close.

Can you tell us more about the Water bottle trick, Eric?

Scubaboard had a thread on the water bottle trick:
