I know, but, is it realistic to have an Atlas Echolot that pings and not to have a sonar? I don't know, just asking. |
The type VIIC had the S-Gerät, which was essentially active sonar with a range of around 4000m. One of the reasons the VIIC is bigger (control room is longer) then the VIIB is to accommodate the transmission sound head.
As far as I've ever been able to determine, nothing smaller, nor designed earlier, then the VIIC had active sonar.
The echolot is a much smaller device and sends out only a low-power pulse. Even then, I'm not sure if the smaller boats (like the type II's) had both the shallow and the deep water versions - I suspect they only had the shallow water versions for the same reasons - space for the higher-power transducer head.
