How can I test that the unit is working properly?

Should you wish to check the operation of your device on land, the easier way to test it is to use our Ocean Guardian tester. Simply push a probe into each antenna and look for both LEDs to blink and you know you’ll fully protected in the water. You can purchase the tester here.


If you’re already in the water, holding either hand close to the antenna, i.e. less than 300mm (12 inches) away, whilst immersed in water and while the unit is switched on, is a handy way of checking the field. 


If the unit is functioning properly, the user should feel a distinct pulsing of the skin muscles of the hand. For surfers, being on the surface of the water and often in bright sunlight, this is the easiest way to check the units operation.
