Ben, these two cams just happen to be my favourites, and my local surf spot is actually U Turns on my SUP. Salt spray is definitely a problem for seaside cameras and these two are covered in the stuff! I look after a live camera at my local surf club and made up a extension pole with a cleaning cloth on the end so that I can regularly clean the lens, saves dragging a ladder out. Is there any chance that these two can be cleaned? Maybe one day, someone will invent a remote camera lens cleaning system!!
