    People are often worried about the risks involved with scuba diving. Like with all sports there are inherent risks with scuba diving, however with the proper training and diligence scuba diving is one of the safer recreational sports.

    Sharks

    Usually when people think about the risks involved with scuba diving they think of sharks and shark attacks. Steven Spielberg did an excellent job of instilling fear in our minds with his 1975 movie Jaws, however the likelihood of coming in contact with a shark or any other large sea animal is actually quite small. This isn’t to say it is non-existent.

    Scuba divers who brave the open waters on a regular basis should consider purchasing a Shark Shield. Shark Shields are a shark deterrent system that creates an electric force field around the diver which will scare sharks away so that they will never come close to you even if they are around.

    Click here to read some frequently asked questions about sharks and shark shields.

    Common Injuries

    The more common scuba diving injuries include small cuts or scrapes from fish, coral or debris that you encounter whilst underwater. To avoid these minor abrasions scuba divers need to have great situational awareness of their surroundings and be sure to keep a mental note of the current direction.

    Dangerous Times

    A New and Different Underwater World

    Scuba diving opens up the underwater world for you to explore, however the environment and temperature is different to the surface waters and can add dangers whilst diving.

    Other Risks

    Not all the risks involved with scuba diving happen whilst you are out diving. The first thing you should do after scuba diving is clear your ears of any water otherwise you may cause permanent damage that could leading to a hearing impairment. Most scuba divers develop a somewhat compulsive habit of constantly clearing their ears.

    Shark Shields

    How long does the battery last?

    Shark shields rechargeable battery lasts for up to six hours when fully charged.

    How does it work?

    Shark shields emit a small electrical pulse at a frequency that is sensitive to sharks; the pulse has a range of 5 metres and is emitted from an antenna that trails from the unit that is about 1.5 metres long.

    Does it ever give you an electric shock?

    Older units in the past had been known to give slight shocks however as the technology has advanced in general, users will feel very little effects. The only time you might feel anything is if you place your hand over the electrodes which may cause some stimulation of the surface muscles of the skin.
