• The world’s only scientifically proven and independently tested electrical shark deterrent technology.
Since at least 2004, surfers, swimmers and scuba divers have been able to buy an electronic shark-deterrent device known as the Shark Shield. The world’s first handheld electrical shark deterrent.
• 12V DC car / boat charging accessory also available. It turns on automatically when deployed creating an elliptical shaped electrical field up to 1 metre (3’2”) in diameter and 2.5 metres (8’2”) in length.
These devices are not effective for the more commonly reported in the media surprise attacks.
Holds the eSPEAR securely in place with a quick release tab for easy access. If sharks have a particular frequency that they don't like, an oscillator circuit could be set up to generate it, and then a transistor could switch off and on every 15 seconds or so, sending the noxious frequency to the coil, which would radiate a magnetic field of that frequency into the water. The claim is that when sharks enter this field, their electro-receptive system is disrupted, causing them to experience muscle spasms and severe discomfort. That's why Australian company Ocean Guardian is hoping to protect swimmers by using the shark's own biology against it. Powered by Shark Shield Technology, the Ocean Guardian eSPEAR is perfect for diving, snorkelling and spearfishing. eSPEAR is a small, lightweight and easy to carry device designed for the everyday ocean user and is powered by Shark Shield Technology, the only scientifically proven and independently tested electrical shark deterrent technology. Use the eSPEAR holster to secure the eSPEAR to your thigh for easy access. Ben is particularly interested in scientific innovation, human-powered transportation, and the marine environment.

The eSPEAR provides peace of mind to enjoy your free diving, spearfishing, scuba diving or snorkeling while supporting the conservation of sharks.
Rebooting the Reef: CNET dives deep into how tech can help save Australia's Great Barrier Reef.
But while avoiding a shark attack shouldn't require Jaws-level escape techniques (or the skills of noted shark-puncher Mick Fanning), you probably don't want a shark to get close enough to test the friendship. Protect yourself during freediving, spearfishing, scuba diving or snorkelling while supporting the conservation of sharks. It could even be made to where it would turn itself on when entering the water! It creates a powerful three-dimensional electrical field, which causes a shark to feel serious discomfort when coming close, turning them away. Sydney-based Ocean Guardian's eSpear utilizes that same system, but it takes the form a "gun" that can be carried in an optional thigh holster, then pulled out when needed. The rechargeable industrial strength designed power module gives you protection for 1 – 2 hours.
The planned retail price is $299. Over 280,000 people receive our email newsletter.
Stalking sharks attack from an area too far away to be deterred by an electromagnetic field. The eSpear can be carried while swimming, or put in an optional thigh holster, The eSpear runs for a claimed one to two hours per inductive charge of its lithium battery, The eSpear is its activated state, with its two electrodes (silver) exposed. Sharks have short-range electrical receptors in their snouts, which the Shark Shield Technology takes advantage of. It has revealed the eSpear, a gun-shaped shark deterrent the company says can protect swimmers from shark attacks, while doing nothing more than giving the shark in question the equivalent of a headache. The fully encapsulated electronic design guarantees watertightness, and a powerful lithium battery provides 1-2 hours of continuous operation. A pledge of US$165 will get you a device, when and if it reaches production. Turns off when held out of water to reload (retract). When it's deployed, the gun flips out a long barrel with two electrodes -- these create an electromagnetic field that repels the shark, according to Ocean Guardian, without causing any physical harm to the animal. Ocean Guardian eSPEAR is the world’s first handheld shark deterrent designed for diving, snorkelling and spearfishing. The world’s first handheld electrical shark deterrent.
If users think that a shark is getting a little too close, they squeeze the trigger.
The Shark Shield eSPEAR is designed to be worn in a holster and deployed like a spear gun to deter sharks. Consisting of two electrodes which create a powerful three-dimensional electrical field when submerged, it causes sharks to experience safe, but unbearable, spasms in their sensitive electrical receptors, turning them away. Never having to worry about a dreaded shark attack while hunting in the depths of the sea! As one research paper aptly points out, shark attacks receive "an inordinate amount of media cover and interest, probably due to humans' psychological abhorrence of being eaten alive.". Being totally passive, one wouldn't have to worry about turning it on when sharks get too close, just when getting in. • Fully encapsulated electronics with powerful lithium battery and wireless charging dock. eSPEAR also represents the next step in Ocean Guardian‘s larger ambition to completely replace shark nets and drum lines around the world. The challenge was to develop a device using Shark Shield Technology that was small enough to be used by everyday ocean users when diving, snorkelling and spearfishing and yet offered a level of protection similar to larger Ocean Guardian devices (developed for surf boards and boats). Obviously, though, users would still be wise to take all the usual precautions when entering the water. Ocean Guardian eSPEAR is the world’s first handheld shark deterrent designed for diving, snorkelling and spearfishing.
A highly visible LED indicator shows operational status and battery life, while a rubberised handle and finger guard provide a secure grip and reduce the likelihood of dropping the baton. Doing so causes a forward section of the device to slide/pivot out from the main body, exposing two electrodes to the water. Discuss: This electromagnetic shark gun is jawesome, have been known to attack electronic devices, Scientists use drones to ease shark fears, Ancient 'Galagadon' shark sported teeth shaped like Galaga spaceship.
Currently out of stock until Nov 2020. It is easily rechargeable with the wireless charging dock. And in a 2018 study conducted by Australia's Flinders University and Fox Shark Research Foundation, it performed the best out of five commercially-available devices. Since at least 2004, surfers, swimmers and scuba divers have been able to buy an electronic shark-deterrent device known as the Shark Shield. While the predators have been known to attack electronic devices emitting low level electromagnetic fields, Lyon says the eSPEAR emits a field roughly 4,000 times stronger than a shark's prey (or an electronic device that a surfer might carry, like a GoPro). eSPEAR is a small, lightweight and easy to carry device designed for the everyday ocean user and is powered by Shark Shield Technology, the only scientifically proven and independently tested electrical shark deterrent technology. Its patented technology is now being offered in a handheld speargun-like gadget, called the eSpear.
Simply attach it to your dive belt or use the optional holster and go! The eSpear uses electromagnetic fields to interfere with sensors in the shark's nose (known as the ampullae of Lorenzini) that it uses to detect prey at close range.

Lyon is quick to point out that it's not a new technology -- research on the effect of electromagnetic fields stretches back more than a decade -- and that electronic deterrents reduce the likelihood of what is an already very unlikely event. Powered by Shark Shield technology, the Ocean Guardian eSpear is perfect for diving, snorkeling and spearfishing. That seems fine, but the best and most effective way of not being eaten by sharks, is not to swim with them, which is the method I would choose. See the stories that matter in your inbox every morning. Our solution was to develop eSPEAR, a compact, lightweight handheld baton that more than doubles in length when deployed. Should you be interested, it's currently the subject of an Indiegogo campaign.
The device is depth rated for up to 100 metres (328 feet). As compared to the existing Shark Shield, advantages of the new device include the facts that it only runs (and uses up its battery) when manually activated, and it can be pointed right at approaching sharks. Small, lightweight, easy to carry, and backed by 20 years of research, it offers powerful and proven shark protection. view twitter Powered by Shark Shield Technology, the world's only scientifically proven and independently tested electrical shark deterrent technology, the Ocean Guardian eSPEAR offers powerful and proven shark protection that doesn't harm sharks or other marine life, giving you peace of mind to enjoy the water.
