Shark Shield - Surf 7

Shark Shield


The Shark Shield SURF7 has been designed specifically for board sports including surfing and windsurfing.

Contents include:

  • Shark Shield unit (with enclosed 7 hr rechargable battery)
  • 2.8m antenna
  • 1 x Mounting Plate
  • Universal Charger (will suit any voltage or frequency).

NB: Does not include deck grip or cover grip.

The Shark Shield SURF7 is a compact, versatile and light weight personal shark deterrent system, which allows you to surf and enjoy the oceans without fear.

The SURF differs from the universal FREEDOM7 unit in several ways to suit the specific requirements of surfing. It is highly recommended that only the SURF unit be used for surfing applications.

It incorporates a longer but narrower 2.85m 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 salt water to function and once this happens the electrodes within the antenna emit a protective electric field.

The unit is secured to the tail of the board, which allows the antenna to be fully submerged. It is mounted to your board by clipping it onto a mounting plate that is fastened to the board with its adhesive backing. Additional mounting kits can be purchased if the unit is required to fit to more than one board.

How it works:
Shark Shield emits a protective electrical field via its antenna. The unique wave form 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.

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 effected 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.

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 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.
