Marine Sonic Side Scan SONAR
We own an IMAGENEX Side Scan SONAR and found the images to be to grainy and the resolution too poor for finding victims. On January 2, I had the opportunity to use a MARINE SONIC unit and we located a drowning victim quickly. I have also used Sector Scanning SONARS manufactured by KONGSBORG/SIMRAD and found them to have excellent imagery. KLEIN makes a good unit also but their prices are typically too high for municipal dive teams. Most teams that I am familiar with use the MARINE SONIC (New York State Police, Hillsborough County Sheriff's Office, Waukegan Fire Department, The National Park Service and FBI)
If you want additional information, please contact Jeff DeMille at Marine Sonic as he is the government sales representative. (Tell him I referred you too, if you would do me the favor)
Good luck. If you need additional information, I can refer you to a bunch of web sites that discuss Side Scan SONAR technology. Also, through the International Association of Dive Rescue Specialists, you team can aquire a unit on an "as needed" basis and this option would be much cheaper than buying one and trying to keep your team proficient in it's use and operation.
