The Shark Shield FREEDOM7 personal shark deterrent system is a universal model used for almost all water activities including scuba diving. Used by professionals and navies the world over, the FREEDOM7 is a safety device providing peace of mind to enjoy your free-diving, spearfishing, scuba diving or kayak fishing while supporting the conservation of sharks.
Alternative products are used for surfing and scientific Scuba divers working in shallow intertidal zones with considerable water movement.
Some of the many activities that the FREEDOM7 can be used for include Diving (SCUBA and Hookah Line), Snorkelling, Free Diving, Spear Fishing, Ocean Swimming, Body Boarding, Kayaking, Jet Skiing, Boating, Aquaculture.

The Shark Shield FREEDOM7 is a compact, versatile and lightweight personal shark deterrent system, which allows you to explore and enjoy the oceans without fear.
The unit incorporates a 2.2-metre flexible mesh antenna, which has been designed to cause minimum water resistance and drag on the user.
The antenna is required to be fully submerged in saltwater to function and once this happens the electrodes within the antenna emit a protective electric field.
Water activities where the user will be submerged requires the user to simply fix the device to their ankle region with the supplied velcro pouch.
Other sports involving craft, such as kayaking, jet-skiing, boating will require the device to be secured to the craft or a buoy in such a way that the antenna will be fully submerged.
How it works:
Shark Shield emits a protective electrical field via its antenna. The unique waveform elliptical field only affects free-swimming sharks and to a minor degree rays and skates. The field generated by the Shark Shield is detected by the shark through its sensory receptors known as Ampullae of Lorenzini, situated on the snout of all predatory sharks. The unique and unfamiliar pulsing sensation emitted by the Shark Shield does not replicate that given off by a fish and does not attract sharks to an area. Shark Shield allows you to hunt, photograph or just swim with all other marine animals roaming freely in their ocean settings.
We encourage people to wear Shark Shield when working in or enjoying the sea to minimize the risk of shark attack but sharks can be dangerous and often unpredictable creatures. While extensive testing has been done and great care is taken to develop and manufacture the Shark Shield range of products, it is impossible to guarantee that all sharks will be deterred under all circumstances. Water-based activities in the presence of sharks is inherently dangerous and is not recommended therefore we recommend that if a shark is sighted that the user leaves the water.
A large pulsing current is emitted from the Shark Shield antenna to produce the protective electric field. When unintentionally coming near or in contact with the antenna it is possible that muscle spasms can occur to various degrees and therefore the user may need to make adjustments to limit contact. In addition, anyone with a pacemaker, are pregnant, or has a health condition that could be affected by the electric field should not use the device. Such health conditions include heart disease, a history of heart problems, peripheral vascular decease, stroke, a history of fainting or epilepsy, or lung disease.
