All this talk about sharks!

I'm wondering what there is out there that can protect me and or my loved ones? Short of a bang stick (which I would like to carry), what's out there?

What about this? Snake oil?

Do Shark Repellents Actually Work?

I've found that bringing a dive camera greatly reduces the chances that I'll actually see a shark. Maybe invest in an old gopro?

A well used knife might be useful according to lore...

Indeed. So you can stab your buddy and swim away as fast as possible.

This guy swam directly overhead. He/she didn't care for my bubbles.

It seems that the shark did a hard and fast movement to avoid your bubbles. It's hard to see in the video because the image is almost out of the screen.
