Side Scan Sonar is not fool proof. A body can be caught up next to or under a log or other debris. It also takes a keen eye to distinguish a body that may be entangled in debris or partially under a ledge or rock. Visual and tactile search is the preferred method in conjunction with SSS and cameras. In many cases individuals who go through ice on snowmobiles are difficult to locate, even with an ROV with SSS and are frequently found a distance from the snowmobile.
