Shark Shield is a unique shark deterrent system utilising a technologically advanced three dimensional electrical wave form. Shark Shield technology is available for recreational users and water sports professionals to help all people enjoy the water with a new dimension – peace of mind; for themselves, their families and employees.
Shark Shield was invented by the South African Government through the Natal Shark Board, home to some of the sharkiest waters in the world. It is used by the Australian Elite Military, the South African Navy the US Coast Guard and is also approved by NATO.
Shark Shield's can be used when participating in any ocean activities including surfing, bodyboarding, longboarding, snorkelling, scuba diving, free diving, spear fishing, commercial diving, kayaking, ocean swimming and boating or fishing.
Shark Shield's provide protection against all predatory shark species including Great Whites, Tigers, Zambezis (Bulls), Makos, Bronze Whalers, among others.
Our shark repellent products repel the sharks via an electric field that induces spasms in the sharks’ snouts. It does not attract sharks to the area or leave permanent damage to the animals, or harm the environment. Our products are proven to prevent shark attacks.

Shark Shield Technology
The electrical wave-form used in the Shark Shield is based on a technology invented by the Natal Shark Board of South Africa.
Predatory sharks have small gel filled sacs knows as ‘Ampullae of Lorenzini’ on their snouts. They use these short range sensors when feeding or searching for food.
Shark Shield is a three-dimensional electrical wave form which creates an unpleasant sensation impacting the shark’s ‘Ampullae of Lorenzini’. When the shark comes into proximity of the electrical wave form (around 8 meters in diameter) it experiences non-damaging but uncontrollable muscular spasms causing it to flee the area.
The field is projected from the unit by two electrodes, which create an elliptical field that surrounds the user. Both electrodes must be immersed in the water for the field to be created. The electrode configuration depends on the model of the Shark Shield unit.
From testing, the closer the shark is to the Shark Shield field, the more spasms occur in the sharks’ snouts. This becomes intolerable and the shark then veers away, and usually doesn’t return.
A distinct advantage of the unique electrical wave-form is that it deters sharks and does no lasting harm to the shark. Once the shark is out of the affected area, it no longer feels the effect of the electrical wave form.
The original technology was released onto the market in 1995 by POD Holdings Ltd, a joint venture company partly owned by the Natal Sharks Board and the South African Government. In addition to being tested by National Military and other
