^ It would be awesome to have one built into a detachable surfboard fin. But looking at the design it looks like you need a length of wire or something running a couple of feet or so up the middle of the board in order to send out the deterent frequency or whatever the terminology is...The Hawaiian ESDS is about this size, but also under investigation by the US government after the US Navy claimed their testing shows it does not have the field or perimeter of protection the manufacturer clams it to have. My friend finds he has to wear booties to prevent shocking himself with his...& the South Oz product is even worse unless your riding a 10 foot Mal or 666.
I've always thought an electronic shark deterrent could be built into a leg rope to isolate the subsequent shock you get when you come into contact with the thing...But Dave has done this by creating a product which remains under the water sending out those gethefarkaway from me signals & for what appears to be a very reasonable price point considering the cost of the oppositions products. The design also does not shock,hinder or restrict a surfers surfing session which is a major advantage.


Go Dave, looks awesome mate...I've been telling the boys down here about them & they're impressed by the design...looking forward to getting one built into my new skud next April
