From the tests conducted to date, and over fifteen years of use in the field, no interference has occurred on vessel equipment such as Fish Finders, GPS or other electronic equipment including camera's and Go Pro's.  


Testing on dive equipment such as the ScubaPro Uwatec range of computers have shown no effect. However, if wearing the SCUBA7 Unit, the Shark Shield field has on some occasions (but not usually) interfered with the Suunto Vytec due to the close proximity of the tank mounted electrode to the tank air pressure transmitter. Many photographers use Shark Shield products with no reported issues. 


Please note, that this was only with the SCUBA7 product and this effect has not been observed when wearing any FREEDOM7 or SURF7 unit.
