Does the Ocean Guardian (Shark Shield) repel any other creatures?

Ocean Guardian powered by Shark Shield technology does not affect or repel fish, crocodiles, dolphins, whales or fresh water creatures as these creatures do not have electrical receptors. The Shark Shield Technology electrical field has only been designed to repel sharks and sting-rays.


However, although animals such as crocodiles don’t have electrical receptors so not effected / deterred in the same way as sharks, if they come close enough and/or touch the electrical field they will experience somatosensation of induced muscle contractions – which is the source of the unpleasant sensation in humans when touching our devices. This has been tested on crocodiles and confirmed, and we are aware of divers who have also successful tested this effect on overly inquisitive seals.
