Inventor Seeks Safer Ocean Travel With Spanner Horizon
Captain H A Gadsen, retired navigator now in London, has devised the spanner horizon to correct false horizons in navigation. The device, aided by a central night wire, aims to keep ships on true course without profit to the inventor. It has seen use by Japanese admirals in war, and English mariners considered mass production.
