The Shipwreck of Blackbeard's Queen Anne's Revenge (Completed Project)
SIDCO's 2000 Dive Season Work on The Queen Anne's Revenge "QAR"
Cannon C20 is found! After careful excavation in the area of the magnetic signature developed using our Schonstedt GAU-30 (see graphic below), cannon # C20 was located exactly where our equipment said it would be! Several more signatures have been indicated on the WNW corner of the QAR site. Basically, our system has proven that an effective electronic survey CAN be done on a site, without disturbing the first grain of sand! Well done, all around!
As seen above, Don Sien of Schonstedt Instruments Co., presented SIDCO with a donated GAU-30 magnetometer/ gradiometer and a ga-72cd locator. The unit in the picture was the very same unit used to find the Confederate Submarine CSS Hunley. Don went back to Schonstedt and built us a new one incorporating some changes to make the unit more effective. Obviously, it worked!
