Shock prevention for all Shark Shield versions
I have been using the Freedom 7 and Surf 7 and Surf+ , all for surfing.
I find the Surf 7 much more acceptable regarding shock discomfort than the Surf +.
I mostly surf 8ft McCoy Nuggets and the front electrode is lifted out of the water during most turns, resulting in very noticeable shocks through my front leg. The other big issue is during eskimo rolls: If the shock occurs just before the upside-down board is covered by the breaking wave, then both hands receive a strong shock.
In each scenario when one or both electrodes are out of the water, the shark deterrent action is greatly reduced or absent, and the shocking of the human user is all you achieve if the device discharges at that time. So you might as well prevent discharge.
I suggest you measure electrical resistance between the electrodes in-between the discharges and stop the next discharge if the result shows that the electrodes are not submerged.
