HornBlaster
Another one:To avoid collisions in areas of restricted visibility, sailboats and powerboats need to produce different signals. For sailboats, which may have to sound either warning, ESC Products has created the HornBlaster® HB-ps Fog Horn Timer. http://www.hornblaster.com/The HornBlaster automatically operates a sailboat's fog horn to send out the proper signal in accordance with COLREGS Rule 35. When under power in fog or other restrictive weather, a 5-second warning is sounded once every 100 seconds. By switching the timer to sail mode, the fog horn produces a prolonged blast followed by two short ones. When connected to the HornBlaster, a fog horn is a simple, easy-to-use signaling device, often more effective than a loudhailer or VHF radio. Louder than the loudhailer, the automatically timed horn also frees up the radio.Installing the HornBlaster is easy. Compatible with most marine horns, it can be hooked up without modifying a sailboat's existing horn circuit. Five simple wire connections join the timer, power source, horn button and mode switch. The HornBlaster fits in a compact 3" x 4" space and includes a handy mounting bracket.Model HB-1/HB1-1m for boats under power* $79.95 Model HB-1S for boats under sail $89.95 Model HB-ps for boats under sail or power $99.95 Contact ESC Products Corporation, PO Box 3998, Sequim, WA 98382.
