Higher Speed Side Scan Pass wreck of Mine Sweeper Lake Washington

This weekend members of Puget Sound Divers tested a new software package promising to allow for greater sensitivity at higher scan speeds, longer scan ranges, and silted water conditions. Below is a scan of the YMS #3 at distances of 400' and 600' with boat speeds of 4.5 mph. One pass was taken perpendicular and one pass parallel to shipwreck of the Minesweeper YMS #3. This vessel is approximately 135’ long and generally gives an excellent image by side scan sonar. YMS3HighSpeedPass200-600wit.gif


These images are about what we were expecting.
