Well, with so many shark deterrents on the market it is hard to choose one that you can feel confident with. Obviously if you are spending upwards of a $100 or more it is necessary to compare the pros and cons of all the available products on the market.
So in order to be able to help you we at Shark Bio Barrier have listed all the most popular and well advertised shark deterrents to make it easier for you to make an educated decision. Hopefully our competitors won’t get too upset with our findings. And remember that there is no foolproof shark deterrent on the market today or the US navy would be using it along with all the other navies and coast guards around the world.
Number One, is the “shark banz” which is quite popular and is all over the internet. It consists of rare earth magnets encased in a plastic wrist band that can also be worn on the ankle. The shark banz themselves are quite colorful which is a drawback in itself because a shark’s food item being fish is also colorful! But the company is appealing to the human to buy the product and not the shark that needs to be deterred. The shark banz claim is that the powerful rare earth magnets will disrupt the shark’s electric sensory organs and confuse it which is an interesting theory but impossible to recreate all the time. Also there is a video of a shark actually eating a shark banz so if it was attached to a hand that might pose a serious problem for the wearer.
The disclaimers on their website pretty much indicate that a lawyer was in the room with the web designer. The magnetic waves can and will disrupt a shark’s electric sensory organ but the shark can and will learn that the magnetic waves aren’t a threat after repeated encounters and will learn to disregard them. Since the product is shipped out of Amazon I can only assume that their product is made in China and Amazon does their fulfillment. Another thing to consider is that all rare earth magnets are not made the same and are not equal in their magnetic properties and their ability to retain their magnetic properties over time.
Number Two, is “shark shield” which is an electronic device made in three different models. According to their website as stated and copied for your benefit, “Shark Shield consists of two electrodes which, when both are submerged, emit a three-dimensional electronic field that surrounds the user. When a shark comes within a few meters of the Shark Shield, the strong electronic pulses emitted by the device cause the shark to experience muscle spasms. This does not harm the shark in any way, but merely causes it to experience a high level of discomfort. From testing, the closer the shark is to the Shark Shield field, the more spasms occur in the sharks’ snouts, which results in it turning away from the electronic field, thereby protecting the user”.
Great claim but the shark can and will learn that this field will not hurt it and maybe the shark will become more agitated because of its effects on its electric sensory organs. And all the models for the surfer, skin diver and scuba diver are very expensive. Not only that is one thing that they overlook and refuse to mention and that is the corrosive effects of salt water. If it is electronic with stuff that can malfunction when wet then it will eventually fail and is the company after a couple of years going to replace it free of charge? Not likely! And going back to the US Navy again this product is not being used by them because they obviously feel the reliability is suspect.
Number Three, is the “shark shocker” which also uses rare earth magnets to deter sharks. It comes in a wrist band that contains the powerful magnets described “as five rare earth neodymium magnets” according to their website. There are different grades of this type of magnet and I am assuming again that this product is made in China. Same claims as the shark banz with little real hard evidence that this product will work to effectively deter sharks when the sharks are exposed to it more than once…
Number Four, is the “shark stopper” which is an acoustical device that is designed to repel sharks. It sends out an acoustical blend of sounds along with the sound of Orcas which are killer whales and supposedly the sharks will hear the sounds and disperse. It is all well and good if the sharks in question have ever dealt with killer whales because these types of whales are only found in the Pacific Ocean. Sharks around the world do not have the experience of dealing Orcas therefore will not react to the Orcas acoustical noise. Besides the fact this is an electronic devise that will eventually fail in salt water. This is a very expensive product and how durable it is, is a question all consumers should ask before purchasing it and will the sharks learn that the sounds won’t hurt them and thus the product will be rendered ineffective!
Number Five, is “shark repulsion technologies” which is a cream that is rubbed on the skin to ward off sharks. The main ingredient is cupric acetate mixed with cupric sulphate,cupric acetate, propylene glycol, methylisothiazolinone, triethanolamine, sodium salt of methylparaben, sodium salt of diaminetetraacetic acid, complex emulsifier, crylate copolymer and water.This sounds like something I wouldn’t want to ever rub on my skin especially when considering that cupric acetate is a toxic substance and it has been proven inconclusive by the US Navy in preventing shark attacks years many years ago.
Number Six, this product is called “shark ban” and is a sunscreen that supposedly not only repels harmful UV rays it also deters sharks from biting you. The purported science is that the semio chemicals that are in the product will deter sharks. It’s your call but the claims are a bit too much to take seriously. The problem I see is that the semio chemicals are encapsulated in the lotion which makes it difficult for the sharks to detect the chemical from a distance which means it has to be very close to you to be able to detect the necronome which are extracts of dead shark decayed flesh. The semio chemical which consists of necronomes has been effectively tested against reef sharks and small bulls but not real man eaters!
Number Seven, is “shark tec” which is an aerosol can containing necronomes that supposedly repel sharks. It is comprised of dead shark semio-chemicals which are extracts of putrefied shark flesh and it appears to repel live sharks. When activated the aerosol can disperses the chemical and creates a cloud. Their research seems to be focused on reef sharks and small bull sharks and seemed to work for a while according to their test results. These type of sharks do not really pose a true threat to humans and testing needs to be directed towards the true predators such as adult bull sharks, tiger sharks, ocean white tips and of course the Great White which are known to be ambush predators meaning that you will not be aware of the shark until its too late. Another issue to consider is prevalent water currents, depth of the water, feeding frenzy behavior and other factors that make the shark a very unpredictable predator. The other thing to consider is where the necronomes come from which are dead sharks flesh. How are these sharks harvested and how many are needed to maintain the production of the essential chemical extract. It seems counter productive to have to kill sharks to collect a chemical extract to repel them!
Number Eight, is chillax surf wax which is a beeswax based wax that is infused with essential oils which includes eucalyptus, chilli, cloves, cayenne pepper, neem, tea tree oil, citronella and coconut oil. The theory is that if you don’t smell like a shark then it won’t see you as a food item. The issue might be the fact that the essential oils are encased in beeswax which may affect their release into the water. Good concept but where does the surf wax go? Bottom of the board or on top? If it is used as a regular type of surf wax then the answer is on top which means that the essential oils can’t be dispersed or detected by sharks.
Number Nine, is the “shark bio barrier” which is a liquid compound consisting of over forty essential oils and a passive magnetic mineral known as magnetite. The essential oils which includes neem, tea tree, capsicum, eucalyptus, camphor, citronella, lemon grass, peppermint and thirty-two more powerful natural oils. It should be noted that plant oils contain amino acids which can be detected by sharks. The mixture is packaged in canisters with a built-in brush so you can brush shark bio barrier on to fins, tanks, swimwear, surf board bottoms, sandals and anything you can think of. The essential oils mask your odor and also create an unpleasant odor that the sharks will detect which is coupled with the passive magnetic mineral which helps disrupt the shark’s electric sensory organs. Nothing is a perfect shark deterrent but this natural product is effective and a good choice based on reliability and cost plus it comes with a thirty day money back guarantee. No other company offers any type of guarantee!
