It's not even a little clunky, it's about 2mm from useless.
The only situation that this comes up is if a creature is hiding from you, and they're within 10 ft. So...probably invisible, and also taking the hide action. If they're merely invisible, you know where they are anyway as per RAW.
And TBC, it's not even blindsight - it only tells you what square they're in. You still are blind to them (so disadvantage on attacks, a big deal for rogues).
The fighting style, available at level 1, is about 10 times better than this ability.
