Equipment Required

Side Scan Sonar

The Side scan sonar system's transducer is housed in a towfish, which is towed through the water a few feet above the bottom. The reflected acoustic returns are processed into an image similar to an aerial photograph, which is viewed real-time on a computer monitor in the towing vessel. Typically, the side scan sonar searches a swath 60 to 160 feet wide at about 2 miles per hour, although other ranges can be used depending upon the size of the object being sought.
Establishing a society is only the first step to making this dream a reality.  It is estimated that over $350,000 dollars will have to be raised in order to finance all the equipment and training necessary.  The initial steps have been accomplished in establishing a non-profit society, but this is only the beginning of a long journey to make this dream a reality.

Why do we need this?


Our experience has highlighted a huge gap in emergency services in Canada.  Police budgets cannot absorb all the demands of this work. The police have a sonar unit that they can use but it is limited to depths of 50 feet or less.  As hard as they try, RCMP divers are limited by the depths they can dive and even if they could locate a victim underwater, in many cases, they would be unable to make a recovery.  As well, consideration has to be given to the risk to divers involved in recoveries.

The sonar equipment utilized by Ralston and Associates can locate victims in water as deep as 900 feet.  Their ROV is limited only by cable length to 500 feet (far beyond the reach of any conventional diver). 

We are inspired by the work of Gene and Sandy Ralston.  They need us to take up the cause and continue this inspirational work well into the future.  There have been cases in the past where private companies have charges families in excess of $30,000 for searches, successful or not.  How much would you pay to get a loved one back?  No family should ever have to make such choices based on their ability to pay.
