On AI182, they located the pingers within two weeks of the accident. The pingers led to recovery of both boxes, and both boxes were ashore within three weeks of the accident.
Unless I miss my guess the depth was considerably less and the terrain considerably smoother where AI182 went down near 51N 15W. That makes location a whole lot easier. I seem to remember reading here that the pinger receivers used were limited to something above the tops of the underwater mountains. The debris is probably down in a canyon somewhere and will be hard to find.

The numbers for depth of pinger receiver, its expected range, and the depth of the mountainous ocean floor where AF447 went down left me wondering, "Why bother except to put on a good show?"
