ORANGE BEACH, Ala. (AP) - A new device aimed at doing a better job of cleaning Gulf coast beaches of oil and tar has been unveiled by BP.

The device, known as the Sand Shark, was demonstrated Tuesday at Orange Beach, Ala., which has been the site of regular cleanup work due to the BP oil spill in the Gulf of Mexico.

BP official Keith Seilhan said the $300,000 prototype will be deployed on Baldwin County's beaches but others are in the works and could be used on beaches in Florida and Mississippi.

The demonstration at Cotton Bayou showed oil and tar balls smearing the Sand Shark's tracks, an indication there is much to be cleaned up still and that some may be hard to get.
