The utility is that it lasts a long time as is (I've never watched the duration run out on a single enemy personally) multiple sonars can stack on the same weakspot - meaning you can get damage multipliers 15x or more on enemies...that's rarely ever needed but it makes weakspots easier to hit by making more too.
