I thought sonar picked up movement but maybe I'm thinking of another piece of equipment.
Can they actually see into the water with sonar?
But the officer who led the search disputed published reports Sunday that divers saw the body of Peterson, the pregnant Modesto woman reported missing Christmas Eve.
Peterson's body washed ashore near Richmond on April 14, a day after the remains of her unborn son were discovered about a mile away.
The Modesto Police Department had hired Gene Ralston of Idaho to search the bay with side-scan sonar. He now believes that what he saw March 13 was Peterson's body, based on where she was found.
"Piecing all the information we have now, I believe it probably was Laci Peterson," Ralston said.
Believe I heard that sonar detects objects up to 300 feet...???
I see Howlin did a great job of answering your question. :)
Kind of odd,,the visibility in the water around all of those abc islands is incredible,,100 feet. We dive there and the only bad visibility is a storm.
No telling how many bodies those dogs are going to find,,wanta take bets?
