Shark Shield’s scientifically proven and independently tested technology, nothing is more effective. It’s a change in the way we manage human and shark interactions. Shark Shield turns sharks away so you can experience more. The ocean becomes your playground.

Shark Shield almost 100% effective as a shark deterrent


How Close is too Close? The Effect of a Non-Lethal Electric Shark Deterrent on White Shark Behaviour.

The study analyzed 322 encounters involving 41 individual white sharks, ranging from 2m to 4m long. Upon first encounter with a Shark Shield, all approaching great white sharks were effectively deterred, staying an average of 1.3m away from a baited canister with the device attached.

After multiple approaches, individual great white sharks came an average of 12cm closer on each successive approach. Only one great white shark came into contact with the bait in the presence of an active Shark Shield, and only after multiple approaches. The interaction in question simply involved a bump of the bait canister rather than a full bite. In contrast, bites were common during control trials.

The Huveneers’ study tested Shark Shield as a deterrent against a shark attack, finding that:

  1. Shark Shield significantly increased the time it took the sharks to take the bait.
  2. Shark Shield deterred sharks attacking a seal decoy.
  3. Shark Shield does not attract sharks.

Shark Shield does not attract sharks


Electroreception in vertebrates and invertebrates Collins S.P. (2010) In: Breed M.D. and Moore J., (eds) Encyclopedia of Animal Behavior, volume 1, pp. 611 – 620 Oxford: Academic Press

This research by Collins proves that Shark Shield’s electrical impulses do not attract sharks: “It is true that the electroreceptive system is extremely sensitive (in the µV range). However, in practical terms and this has been born out in many behavioral tests, the electroreceptive system is a relatively short distance sense often working in the 30-60cm range. Since these animals use this sense to detect the presence of living prey items that may not be otherwise detected (i.e. under the substrate), they are really working at their detection limits. Therefore, although theoretically the Ampullae of Lorenzini can detect very low strength electric fields, they do not use them to track animate objects over these long distances.
