There is no better way to avoid sharks than to hide in front of them. This diving suit developed by SAMS (Shark Attack Mitigation System) and the University of Western Australia on 20 13 has been in use? The color blindness of sharks.
The diving suit has two patterns and disturbing color combinations, so that the wearer can blend in with the underwater environment. Of course, SAMS can't guarantee that wearing this diving suit will not be noticed by sharks at all, so you may need several backup measures to ensure safety.
2. Anti-shark bracelet
There are several kinds of anklets and bracelets on the market that can drive away sharks. Although it doesn't look much different from the sports bracelet, the shape of Sharkbanz is more attractive.
The development team said that this bracelet has patented magnetic technology, which can keep the shark away from the wearer, and the magnetic wave released by the bracelet will bypass the shark's inductive sensor. Although this bracelet has been proved to be effective in more than a dozen kinds of sharks, it may not have much effect on great white sharks because they attack in very different ways.
3. Anti-shark surfboard
Lawrence ampulla of shark nose is very sensitive to current, so many shark repellent techniques take advantage of this physiological feature.
Shark shield is a device that can be connected to surfboards, rowing boats and ankles, and it will generate a three-dimensional electric field around users. If the shark gets too close, it will cause muscle twitching, but it will not be seriously injured.
4. Shark tracking application
If there is a simple application that allows you to track sharks in the nearby area, you may not need to buy so many anti-shark equipment. OCEARCH's Global Shark Tracker is a tool that can track sharks marked as research objects by non-profit organizations.
Although the main purpose of these data is to help protect, suspicious people can also use it to protect themselves. Bonnie Holmes, a tiger shark researcher, said: "It is great to be able to track the movements of sharks in real time. If people want to use these data for security reasons, it is completely reasonable."
5. Shark drive cable
If you are very afraid of sharks and are willing to lobby the local government, you can try to get them to install shark-proof cables on local beaches.
Researchers from Cape Town, South Africa began to test this technology at the end of 20 14. This 100-meter-long cable hopes to drive sharks away by releasing low-frequency electric pulses. This kind of cable is not dangerous to people, but it may sting if touched.
In fact, this cable may be more suitable for sharks. Although shark nets and drums are forbidden to protect people on the beach, they do much more harm to sharks. From 2005 to 2009, about 59/kloc-0 sharks were caught in the net in South Africa, and only 13% were released alive.
Don't go in the water.
Finally, we can refer to the suggestions of Australian shark attack records to reduce the risk of being eaten by sharks, such as avoiding swimming in the sea in the evening or at night, or not going into the water when fishing schools are particularly crowded. If you don't like simple rules, then you may need a boat.
