View Full Version : Water Bottle Shark repellent???

I caught a part of a show on Animal Planet where some dude used a partially filled water bottle to scare sharks while diving. The bottle was about 3/4 full and had a few air bubbles. Whenever the shark would approach, he would rapidly squeeze the bottle and the shark would bolt. Anyone ever seen that before? It appeared to be pretty damn effective.

Maybe webers could finally get that shrimp boat dive done:D

BTW, the program is called Perfect Predators if you want to catch it next time it comes on.

Is it the noise from the bottle crunching and the liquid sloshing that scares it off? And to think that people buy shark shields for as much as they go for when all you need is a half-drank gatorade.

I saw this episode too and while it appeared to be effective, I just cannot BELIEVE that it is.

(Of course, please disregard the fact that I currently own a $500 SS and what a FOOL I'd be if my Zephyrhills Spring Water bottle was the perfect deterrent! :slap:)

I'm pretty sure I remember the annoucer explaining that the vibrations the crackling bottle (half-filled only with air and H2O) sent out under water "scared" the sharks off; much like the irritation that the SS casuses to the sharks' ampullae of lorenzini.

I'll also add that the divers who were filmed during this daring feat were neither hunters nor dragging around a stringer full of bloody fish.

I've got five bucks that says it would have been a different scenario if they'd brought lunch with them.

Yep, the guy seemed to think it was the sound that was f'n up the shark's sensory system. I caught the last fifteen seconds of that portion of the show and was amazed at how the shark would haul ass when he would crunch and slosh the water bottle. Think I'll throw one on a clip and try it out next time:D

I wonder what makes someone say "hmmm, I think I'll partially fill a water bottle and try to scare away sharks with it". I know that sure wouldn't have crossed my mind.

That was great!

He called it sensory overload to the shark's lateral line. Remember that sharks are attracted more to the vibrations of a distressed fish than they are to the scent of blood. Sharks are extremely sensitive to vibration, so the squeezing and crunching of a half filled water bottle sent super strong vibrations through the water and it hurt the sharks.

The same way if you were to walk up to me and I stuck one of those portable air horns in your face and pushed the button. Major sensory overload.

Ha!! Great example!!

Hell, if you did that I'd be more concerned about getting kicked in the nuts than hassled by a shark! ;)

Well, my sister Bunny protects me from nut kicking women (as well as men under 240 lbs.). :whistle:

I'll stick with the old reliable .223.

Getting eaten alive would be bad enough, but furiously crunching a plastic bottle would make me feel pretty f-ing stupid in those last few moments of life.

Think about it. When they pull your severed torso and tattered dive gear out of the water what do you want them to find? A bent shaft with a discharged powerhead or a crumpled plastic water bottle?

I'll take the former. :D
