Sharkbanz is a US company that has developed magnetic technology which based on their research, development and assertions, has the ability to potentially reduce shark interaction by using a magnetic field. The Modom Shark Leash uses Sharkbanz magnetic technology that according to Sharkbanz research, can damage electrical and medical devices, so make sure the customer keeps the protective box. This box should also used for air travel. It is recommended that the Modom Shark Leash be kept at least 60cm (24 inches) away from electronic devices, including electronic scuba equipment, GPS and compasses. There is no guarantee of no shark interactions that may or may not result in injury or death, and this product is all about potentially reducing the risk, similar to wearing a helmet on a bike or a seat belt in a car.
