we use those shark pod things when spear diving... works a treat. Not to keen on having one when surfing though.
was out a derdes the other day when a massive school of bait fish being worked by dolphins and birds moved right passed us, not 200 meter from where we were. I decided to get out of the water and wait for them to pass.
Seen it when diving how sharks like to hang around at the bottom of those bait balls... and I did not want to become another shark stat.
So be careful out there and be aware of whats in the water with you.
Keep on charging
