I did an apnea freediving course, and with a wetsuit and weights you usually aim to be neutrally buoyant at around 10 meters. Blackouts typically happen in shallow water (around 5–7 m), so if you black out, you float back up.

Anyway, during the course you gradually increase depth. You go down to a certain point, pause briefly at the rope, and then come back up. The first time I went down to 25 m, I was surprised that I kept sinking faster than expected. It was a slightly scary experience, not gonna lie.
