The pingers ping continuously and suppossedly have a range of about 3 miles but water can do all manner of strange things with sound in terms of redirecting, blocking and distorting.

That detectors are picking up sporadic pings indicates they are probably close enough that even if the pinger batteries fail, a grid search of the ocean floor in that area could be done and the debris field located in a resonable amount of time.

debris field? no, I am extremely skeptical of a debris field.
