Here is a solution for the shark fearful.
I heard North is planning to incorporate the device in the new Rhino II bar :smile:

Electronic Anti-Shark Units for Swimmers Launched


SYDNEY - (Reuters) - An Australian firm unveiled an electronic shark repellant unit on Wednesday that attaches to a swimmer's ankle and emits an electronic field to ward-off sharks.

The electronic shark repellent unit is a miniature version of cumbersome anti-shark pods used to protect triathletes in Sydney Harbor during the 2000 Olympics and worn by abalone divers.

The personal anti-shark unit weighs one pound and has a battery life of two hours. A slightly larger unit for scuba divers weighs 1.3 pounds with a battery life of four hours.

The swimmer's anti-shark unit will retail for about $240, said SeaChange Technology Pty Ltd which has miniaturized the original Shark pod technology developed by the Natal Shark Board in South Africa.

SeaChange said testing of the electronic shark repellant units in waters off South Australia and South Africa, both renowned Great White habitats, showed sharks were repelled at about six to nine feet from a swimmer.

The diver's pack repelled sharks at 12 to 15 feet.

The electronic field affects the shark's nervous system through sensitive receptors near its snout. An initial mild discomfort increases as the shark approaches the field until it causes intolerable muscle spasms.

``It puts out a very precise electrical field that sharks perceive because of a hunting sense they have,'' Jerry Kleeman, managing director of SeaChange, told reporters.

``So as sharks get closer to you they will veer away very rapidly as it becomes uncomfortable for them, but it doesn't cause them any lasting harm. It also does not impact on any other marine creatures or humans.''

SeaChange is working on electronic shark repellant units which can be used to create a safety zone off the back of boats and yachts and a larger version for beach protection.

``Apart from protecting human lives, the beach protection units would enable the removal of existing net and hooking systems that are responsible for the slaughter of a range of marine life, including protected species such as whales, dolphins, turtles and dugongs,'' said the company in a statement.

SeaChange sports a variety of investors, including Adelaide-based Gerard Industries and Playford Capital, joint owned by software giant Microsoft Corp, computer management firm Electronic Data Systems Corp and the Australian government.

yeah I've heard that the electronic thingy works really well... the only trouble is that if your a few meters away from someone who has one on and you don't then you'll be dealing with one pissed off buzzed out shark.
not so good
hence unless everyone in a diving group has one then no one wears one

I've had the privilege of seeing plenty of sharks diving and fishing on the Great Barrier Reef.(I live in Cairns,Qld). We don't get those nasty Great Whites up here so sharks have never bothered me a great deal as long as I can see them. It would be nice though if someone came up with a repellant for crocodiles and box jellyfish. These creatures do bother me a little. Fortunately our kiting season is the winter. Crocs are generally more interested in warming up their cold blooded bodies on the river banks and the jellyfish mainly turn up in the summer. I hope.......
