Sounds about right.
Both Blair and Rohwer recount a number of instances where boats had been driven deeper and still successfully attacked. Regardless of the accuracy of the SH3 sonar model, the overall effect is probably reasonable since many of the factors affecting sound propagation were unknown at that time.
Without knowing what the conditions are like there is no way to assess the potential "realism" of the possibility of detection.
Late war chances of survival suck for many reasons, consider this one of them.
