I agree. The sonar is GREAT but productive for locating larger items like tires, bags, cars, etc.
How is the sonar going to locate one bone? That's why having these divers there is a good thing.
Just my opinion.
Ok. We have a sonar "fish finder" attached to our fishing boat. I'm thinking TM's side sonar a more sophisticated version of the same thing.
It shows the bottom structure, but I doubt it would be able to pick up a tiny bone.
Anyone agree?
Got ahead of myself. Here's a link for "side scan sonar". Interesting info worth taking a look at.

Snipped:
" Law enforcement and search and rescue personnel are frequently required to search for drowning victims as well as missing objects underwater. Typically these searches have been conducted using divers, underwater cameras, and water-trained search dogs. Underwater searching by divers is time consuming and can be very dangerous depending upon water depth, visibility, current, and underwater obstructions.
The lack of good point last seen information can extend the search area to tens or hundreds of acres. Often the search area is large because there are no eyewitnesses or the eyewitnesses cannot accurately identify the place where the drowning victim or object was last seen. Large areas are often impossible to effectively search with traditional techniques and consequently searches are terminated after several days and recovery is left to chance.
Gene Ralston, an environmental consultant who specializes in water related environmental issues, has frequently volunteered his equipment and time to assist the Idaho Mountain Search and Rescue Unit, local and national authorities in searching for drowning victims. In early 1999, Gene had the opportunity to experience the successful use of side scan sonar to search for a drowning victim.
Recently, side scan sonar systems have been developed using medical ultrasound technology to dramatically increase resolution of targets such as drowning victims. "
With that being said, though, I really feel more comfortable with the area being searched by divers so it can be crossed off the list of possible areas.
