A submerged u-boat is big, clunky and slow. Once the depth charges were in the water I think it became a matter of luck as to how close they were, and all were going off pretty much at the same time. Then the destroyer would make another attack. The time for evading is just before they drop. It seems to me it's like a bomber trying to evade flak; by the time you know where it is it's already too late.
That they had such a device (or may have) is interesting. That it didn't work too well doesn't surprise me.
