Make sure you can be heard Saturday 03 March 2007 In restricted visibility all vessels are required BY LAW to make the sound signals relevant to their situation eg at anchor, underway but not making way etc. These signals have to be repeated every 2 minutes and doing this with a simple push button is a real bore. We have developed HEAR-ME to take the pain out of this. Connect HEAR-ME to your existing horn push button and provide it with a 12/24V supply and it will take on this task leaving you free to watch and listen. HEAR-ME has been designed primarily with motor cruisers in mind as they usually have horns fitted.
