Shark Deterrent

South Africa with its pristine coastline, sandy beaches and incredible waves, offers some of the best surfing in the world, but like the Ozzies over on the other side of the Pacific, we too have a large shark population that we share our coastal waters with. While relatively infrequent, shark attacks are a reality of surfing life in South Africa. As featured on National Geographic's DSTV show "Australia's Deadliest: Shark Coast"SAMS (Shark Attack Mitigation Systems) shark deterrent technology from Australia gives you that little bit of extra piece of mind to do what you love best – surf.

Sharks use all of their many senses to find prey, but once they have found it, they rely on their eyesight to determine whether to attack it as a confirmed prey item, have an investigative bite or simply leave it alone.

The patented, complex SAMS pattern, developed by Professor Nathan Hart and Professor Shaun Colin, of the Oceans Institute at the University of Western Australia, gives water users the best chance of being left alone by a shark should it locate you in the water.

  1. The pattern’s unique scientific design identifies you as being far removed from anything that usually appears on a shark’s natural menu.
  2. There is a long anecdotal history of evidence that sharks are genetically programmed to treat striped objects with caution. Some theories claim that striped objects in the ocean are considered dangerous or poisonous.
  3. When viewed by a shark from below, water users are presented as a silhouette. The SAMS pattern increases the distance at which you can be identified correctly and not mistaken for a seal, for example.
  4. While it has been discovered that predatory sharks see in black and white, the colours used in SAMS patterned stickers and wetsuits form the best contrasting pattern for sharks to identify you as a foreign, non-prey object. 

Initial independent testing of the design materials was conducted in 2013 in a live ocean environment by the University of Western Australia’s Oceans Institute off the coast of Western Australia.  This involved filming the behavior of sharks attracted to a baited 'control' (essentially a drum of chum) covered in ordinary wetsuit material, alongside a similarly baited test wetsuit incorporating SAMS Technology. This field testing programme was followed by National Geographic and a documentary was recorded with some spectacular footage. Go to for more information. While the sharks hit the black control chum drum again and again, the chummed SAMS wetsuit drum was left alone.

NOTE: At a glance the designs may appear relatively simple to the human eye, however the SAMS patterns apply detailed scientific data and combine a number of variables including colour, contrast, shape and size to achieve maximum deterrent effect. Upon closer observation, you'll notice intricate detailing. This product is the genuine article, produced in SA under licence to SAMS Australia. BEWARE OF IMITATIONS THAT DO NOT USE SAMS VERIFIED PATTERNS!

Unlike shark nets, the shark-friendly tech incorporated into the SAMS surfboard and body board stickers and wetsuits offers ocean-loving surfers an environmentally friendly way to enjoy the ocean with sharks, while equipping yourself with the best chance of being left alone by them. Surf MORE, Stress LESS.
