There is no defined detection range... but I found this:
Deep-water Black Box Retrieval - November 2009, Volume 13, Number 09 - Archive - Hydro International
This states the typical detection range would be 2-3km, with 4-5km under optimal conditions...
But wouldn't you want to use one (or several) of these:
SEA 00C2 Salvage Assets: MINIROVs - Standard Vehicle and Open Frame Vehicle
Come to think of I thought they did have access to a similar device...?
