GEARBAG Magnetometer helps search for wrecks off South Africa Memories have huge staying power, but like dreams, they thrive in the dark, surviving for decades in the deep waters of our minds like shipwrecks on the sea bed – J.G. Ballard Amongst the right tools in the search for shipwrecks, magnetometers are a ‘must have’ for the serious explorer. Magnetometers detect variations in the Earth’s magnetic field caused by iron or other magnetized material such as brick or rock. While a side scan sonar detects only what is on the seabed surface, a magnetometer detects objects buried under the ground. A small dive club in Capetown, South Africa, The Wreckless Divers, currently uses JW Fishers’ Proton 5 magnetometer for their important searches (facebook. com/wrecklessdivers). The group operates at depths up to 120m with some on rebreathers, and others relying on open circuit scuba. According to group founder, Bruce Henderson: “There is an enormous number of shipwrecks off our coast dating from the 1700’s. We are very keen to find the more interesting of these wrecks and dive on them. In particular, a German ‘merchant raider’ called “The Wolf” laid mines off Cape Town during World War I and sank at least 4 major merchant vessels. To date we have found an old fishing trawler and a whole bunch of magnetic rocky outcrops. But it’s been fun and we will persevere.” Bruce says when they ran into a bit of trouble when they first received the magnetometer they called the JW Fisher’s office and their top technical guy patiently took us through the set-up procedure. ”We were very soon up and running. This was amazing to be able to call up the JW Fisher’s team from Africa and have them so helpfully take us through the system.” Treasure detectors in the movies! There comes a time in every rightly constructed boys’ life when he has a raging desire to go somewhere and dig for hidden treasure – Mark Twain JW Fishers’ say their search equipment has been a part of numerous high-profile, treasure hunting films. Paul Walker and Jessica Alba used their Pulse 8X in Into the Blue and Matthew McConaughey and Kate Hudson went looking for gold on a sunken Spanish galleon in Fool’s Gold. JW Fishers has also featured on Rob Riggle Global Investigators and on The Curse of Oak Islands series. In 2012 James Delgado, then with the National Oceanic and Atmospheric Administration (NOAA) estimated there are a million shipwrecks underwater. “I would say the majority of them remain undiscovered,” he said. “We know more about the surface of the moon than what’s at the bottom of the sea.” Nelson Jacas is an avid user of the Pulse 8X underwater metal detector, and has journeyed across the globe locating antiquities. He has found a Viking ring, many 1700 era coins, and a one-of-a-kind gold cross in England! University of Rhode Island’s Dr Bridget Buxton hit the payload in 2015 when her team found over 1,000 gold coins off the coast of Israel with their P8X system. Her adventures have yielded large cannons, anchors from lost ships, and a swivel gun from a 16th century shipwreck. On a famous 2,050-year-old Roman shipwreck at the Greek island of Antikythera, first discovered in 1900 by sponge divers, Greek diver Alexandros Sotiriou has discovered numerous artefacts including an intact table jug and a bronze rigging ring with the help of a JW Fishers Pulse 8X underwater Metal Detector. Perhaps the next big find could be a rookie diver searching the right place at the right time with the right equipment! 54 Dive New Zealand | Dive Pacific
