1. A waterborne search system for submerged articles comprising:

  • a surface platform movable over an extensive target search zone;

    article responsive sensing means operably carried on said platform for detecting the presence of said articles;

    control means carried on said platform and operably coupled to said sensing means for receiving signals from said sensing means upon detection of the articles and for transmitting said signals;

    a control vessel carrying data reduction equipments operable to receive said sensed signals from said control means and for displaying said signals in a meaningful presentation;

    said presentation being in the form of a visual chart display of magnetic anomalies;

    remote control means interconnecting said platform and said control vessel for directing said platform to follow a series of parallel sequential transverses about said target search zone;

    said sensing means including a pair of magnetometers trailing behind said platform in substantially fixed spaced apart relationship;

    said control means carried on said platform and said data reduction equipments on said vessel constituting a data link and further including an observation aircraft in close proximity to said target search zone incorporated into said data link;

    said platform comprising a self propelled boat remotely controlled and directed by said control vessel;

    said platform comprising a pair of skis connected by braces so as to be in fixed parallel spaced apart relationship; and

    said platform further including pivot attachment between said braces and each of said skis and wherein each of said skis includes a concave underside adapted to stabilize directional movement.
