No electrical device manufacturer can remove all of the risk of interfering with an ICD, particularly devices that generate or transmit energy like microwaves, mobile phones, power generators, transformers,power tools, along with marine equipment such as radars, EBIRB's, PLB's, fish finders and of course electrical shark deterrents.
We refer ICD users to this reference website on safety precautions for ICD’s, these safety precautions exist across a range of products in the general public community which a person wearing an ICD could be exposed to. Electrical shark deterrents fall within the potentially distributive items like electrical pet containment systems, electrical fences, some power tools, etc. Awareness of these risks assists ICD users to be alert to the types of devices to avoid.
Like most of the potentially disruptive items, the risk increases with extended periods of time and close proximity to them. In the case of an electrical shark deterrent in an ocean environment, it is difficult to see a scenario where an ICD user would be located unaware, and/or for an extended period of time, near an electrical deterrent. Our devices are used primarily by individual divers and surfers, neither of which are usually located in a beach/sand environment, or next to someone for an extended period. Also noting the devices do not function out of the water, they must be submerged to be active.
Over the past twenty years electrical shark deterrents have without doubt saved the lives of many people. Providing normal ICD safety precautions are taken for potentially disruptive items, such as not wearing a device such as ours, and general safety warnings provided to ICD users are adhered to, electrical shark deterrents present minimal risk to public safety.
