I don't know that remote viewing would be very good at finding things like that. Here is a quote from an email I received selling a dowsing program. As you can see it more describes a general area, unless there is something really unique in that area that would identify it, it would be difficult to pick out. I have read accounts of people finding lost items though, so I may be wrong. For example a living room might not be different enough from a bedroom to differentiate between the two.
"However, remote viewing is a descriptive methodology. That means a remote viewer can often accurately describe the setting of something that someone wants found, but can't actually give you a street address, or latitude and longitude figures, or any other standard alphanumerical-type data that we humans use to specify a location somewhere on the face of the globe. That makes psychically "finding" things much more difficult than many people realize.
For example: I am often asked "Why haven't any remote viewers found Usama bin-Laden?" I answer that they probably have. More than one viewer has no doubt well-described the location of the world's most notorious terrorist. Let's say he is in a cave in some mountains in Afghanistan. Working "blind" (remote viewing protocol requires that a viewer not be told what her target is - so she would have no idea that bin-Laden was to be the focus of her perceptions), the viewer might describe a robed and bearded man in a strange, long, narrow, room with rock walls, a carpet on the floor, in the middle of some mountains. Upon hearing the report, an excited intelligence analyst might exclaim "That's exactly right! Now ask the viewer where this person is." The viewer's annoyed response might be, "But I just told you where the person is: In a long, narrow, room with rock walls and a carpet on the floor in the middle of some mountains!" The remote viewer has indeed found the target, but has not located it. The most to be hoped for is that a viewer will describe a recognizable landmark. But in places with few (or too many) obvious landmarks, mere description doesn't usually work very well. "
