I just recently brought a shark shield for diving and wondered if anyone has used them for windsurfing? One other thing I wanted to mention which I am slightly concerned about is last weekend I took my boat down to Margaret River for a spot of deep sea fishing. I was anchored off Point Naturalist reeling in the fish when I hooked a shark. Once I got it too the surface I realised it was a Port Jackson (1.2m). I remembered I had left the Shark Shield in the boat so thought what a great opportunity to do a few tests! To my girlfriends complete dismay I dropped it over the side expecting the shark to have some sort of reaction, but nothing. It just sat there smiling up at me. I did test it was working and received a tingling feeling in my hand. I have a huge respect for sharks so let him go. Next time I go out I’m going to try and catch another one and perform some further tests. I was expecting some server spasms. The device was aprox 4/5m away from the shark. I'll let you all know how I get on.

I found out the technology does not work on Wobbygongs, Carpets, Dog and Port Jacksons as they lack the Ampullae of Lorenzini sense that the wavw form works on.

In general it works on most free swimming sharks, not the bottom dwellers.

It works on the most dangerous sharks such as the Great White, Bulls, hammerheads, white Tip, Reefies Tigers that cause us the problems, also the larger the shark then the greater the deterrent factor.

Off diving tomorrow at Rotto!!

It was always about the Ampullae of Lorenzini that sense the wave form, upon sensation of the wave form the neuron's in the Ampullae potentiate, sending a signal to the amydala that a threat is imminent, causing the flight response!

Researchers have found that In humans electrical stimulation of the left lateral amygdala causes an extreme terror response, and that electrical stimulation of the right dorsal amygdala causes an extreme rage response, yes we are as primitive as sharks, how embarrassment!

For those interested the human fight/flight response works as follows:

firstly a perception of threat occurs via one of the senses, this is processed by both the the thalamus which sends a signal to the amygdala, and the amygdala itself which registers the threat, the amygdala in turn sends neural signals to the hypothalamus, and thalamus, that a threat has been detected, if arousal and neural firing is high, the hypothalamus shunts neural messages to the pituitary gland, which in turn sends a signal to the adrenal glands, dependent on the strength of the signal received by the adrenals, will determine the amount of adrenalin that is released into the blood stream causing the fight or flight response!

Can you tell I'm bored and underworked??

its kinda like slapping a shark in the face, after a while they'll stop fleeing and bite back so be careful how you use it.

Just went diving out at Rotto over the weekend. I have to admit it did give you a little more confidence while being in the water. You can really feel it work when you accidentally make contact with the electrode , gives you one hell of a boot! The units available at the moment are not practical for windsurfing but they are bringing a much smaller unit out which connects directly to the board, their about the size of a cell phone. How many windsurfers have ever been taken anyway!! Kite Surfers are way more at risk as all their really doing it trolling using yourself as bate!!!!!!

Comrade Hardie,

This amygdala you speak of, this is like what is found in aligator as well, yes ?
Like is seen on Adam Sandler movie 'The Waterboy' yes ?
This is what make aligator angry yes, like shark... not cause he has many teeth for brushing, no ?

I think with right amount of salt and vodka this amygdala from shark and aligator be good for eating, you want try, yes ?

My dear Kremmy babe, if you are referring to the reptilain brain, well sort of correct, but the amygdala is located in the Limbic System in humans which is referred to as the (mammalian brain), was only mucking around about the shark, but serious about the human fight/flight response! So not sure what you'd find in alligator or shark brains? Might be tastey tho, particularly the vodka bit!!!!!

pfft reef sharks arent dangerous... does anyone know wat range you can get with these. Coz i still like to see sharks when i dive, i just dont want to be eaten by one.

Oh yeh I saw a hammerhead in bunker bay on monday... like in the bay... it wasn't very big though, and my girlfriend screamed when I tried to go swimming with it.

FYI

I believe the new surfing unit should work very well for windsurfers. As you may be aware we will offer extra mounting plates for people that have a quiver of products.

We are reworking the antenna to make it smaller and thinner. The unit will mount right at the rear of your board with the antenna trailing a foot behind. If surfers can use it with the “cut-backs” etc. then I can’t see it causing any problems for windsurfers.

The only question is when you come off your board, the protection is with the board and not the rider. I have had discussions about this and am told this doesn’t happen too often and would not be a concern.

At this stage we are trying to obtain a 5hour battery run, I hope this is enough for you guys. Size is about the same as a cell phone.

Thanks again Dave.

As they say, there are lies, lies and pure statistics. Media hype is definitely alive and doing well in our day and age. If it sells an extra newspaper, magazine, or technological development it will definitely be worthy of mass hysteria or at least a favourable front page mention.

I am happy to put my faith in statistics and hope they are right when they say that the number of shark attacks are not increasing, however the reporting on such things are. This gives me some comfort when I am lying in the water far from shore while I attempt to recover my board and rig from a misjudged jump, gybe or an unexpected crash.

Admittedly I spend more time on or in the water than the average person, hence my chances of being attacked must be higher. However when I consider the number of people for example that were at the beach on Sunday - morning and afternoon, I then think of the thousands of beach-goers in a day times the number of days in a year and then think about the chance of getting attacked. Comforting...huh? If we all had such an innate fear of getting attacked I believe that sports like ours would be extinct.

Get out there, relax and take a very remote risk. A statistic shown on the media hyped telly the other day said that more than 200 people per year are killed around the world by dodgy toasters and less than 20 people per year are killed by sharks. Mental note...must stop eating toast.

Better still stay at home, get old and die in a state of mental and physical inablity to clean and look after yourself.

Was in thailand (Ko Tao)diving and snorkeling with these absolute peaceful fellows. was souroundet by them in sizes from baby to nearly my size 185 cm. could nearly touch them, but they dont like that. there was these little anoing fish who suck on the sharks and tryed it sometines on me. and they bite me many times. dont hurts much but it is not a nice feelin, when you swim with sharks and something bites you suddenly in the back.
I heard that sharks notice straight way, if you are nervous or relaged and nervousness makes them want to play their hunting games.
so stay relaxed, when you face a big white with open mouth next time.

heres my thoughts, as we all know, statistics like "you have more chance of choking on peanut butter than getting bitten by a shark" etc etc have no real relevance to us, but..... as I last went surfing with my 16yo daughter, this thought came to my head, (she by the way has seen a 4' shark under her out surfing and says she is now calmer about the whole thing now she has seen one and realises it basically is just a fish), so realistically, as a kiter or windsurfer or surfer, we have a much higher chance of drowning, but we never enter the water with that fear in our head! but we always enter the water thinking, yes THINKING about being eaten by a shark, kind of like the boogie man in the back yard when you were 8, if you think he is there, you will believe he is! so chill out, hit the water, remove the thought and have fun! and on the drive home dont think about the car crash you may have, or the peanut butter that may choke you! all thoughts oh by the way this is from a person that is scared ****less of the thought, but try to think with this mindset to make it a fun day out

16 y.o daughter hey ... hahaha jj m8
the way i see it is if ur just in the water for sport or something dont bother but if u are going to be in the water for multiple hours on end like commercial divers, proffesional surf photographers or what ever it may be a consideration but for us kiters, surfers windsurfers or what ever the chances are slim enought not to even worry about. ya should be more worried about how hard ur goin to hit the water after busting your next biggest trick..so get out there and have fun

Hi Guys
I'm a kitesurfer and bought a shark shield 12 months ago. The Freedom4 I think with 4 hours life.

Kiting with it is not a problem and I can't imaging it would be any different with a windsurfer. Occasionally my trailing foot might get a zap but I just adjust the angle of my feet slightly. Not a problem. It does **** me though when I'm laying back in the water about to do a water start and the little tail floats by my bum.

In terms of risk: measure it from the amount of time you spend floating in the water, not on your board. And how many swimmers spend their time 100m - 400m off shore floating around. Sharks probably only spend 5 minutes a day feeding and you've got to be pretty unlucky to be there at dinner time, but I for one feel a whole lot more secure having the shark shield than not. I wouldn't be out there doing stuff if I didn't have it.

I have to admit this is something I worry about, since I like to try a lot of new tricks and consequently spent quite a lot of time trolling about like a big lure. Also the area I usually kite is quite deep so probably would be some big boys around there somewhere.

I am seriously considering buying the freedom shark shield, cos I scare the crap out of myself every time my leg brushes something (usually Jellies, which sting, but at least they dont take my leg off I would only need turn it on when I come off the board, so wouldn't be running all the time, but it would certainly ease my mind. Has anyone else got one? How accessable is the on / off switch?

I have one... the switch is on the side of the unit... just stick ya finger in and move it... but i think u are ment to leave them on all the time to insure they work... The zap isnt that bad just comes as a bit of a shock sometimes... specially when u (diving) are down in a cave and it falls on ya leg

Given how kiting can chuck you about, I would be more scared of getting stung on the eyeball or on the nuts or that the thing would get wrapped in a line and sting you continuously (again on the eyeball or the nuts but anywhere would hurt in this scenario):P

Also can you sting your mates when you're wearing one. This might possibly lead me to buy one.

Oh and how come David Murray started the thread saying he bought one and then moved on into retailing them. No problem with pimping but don't like it dressed up as a forum. Hope you get stung on the nuts. :)

Would seem like a waste of money for kiting - I found once my foot straps are set up right I almost never loose my board when I fail trying a trick, I could imagine the chance of it hitting a nut in a backloop board off though - oichies!

wal269 what are you 12? You appear to have been interested in this topic otherwise you wouldn't have replied to it. I do not retail them, just thought being a windsurfer I'd pass on the information. Next time I'll keep it to myself. I brought one for Diving and was obviously interested in seeing if anyone had used them for windsurfing. So enough bitching. Tried mine windsurfing and totally in the way of things. [}:)]
