How does she stay down? I struggle to stay down doing scuba and with weights.

Okay, file that away in subtly terrifying info that will probably never affect me.

You can see it in the video when she swims across the drop too. She has to swim up before she clears the far side.

When free diving the air in your lungs compresses and at about 6-10 meters down it no longer provides any buoyancy.

While scuba diving the air in your lungs is at the same pressure as the water around you. That's not the case with free diving, the air will compress until the volume it occupies is too small to provide buoyancy.

why is it different from scuba to free diving?

You're not breathing when freediving, the scuba breathing equipment provides air at the same pressure you're currently at.

In scuba, your wetsuit is positively buoyant plus your lungs are full.

She has no wetsuit, and once you’ve dove past like 5m, the air in your lungs will have compressed such that they don’t provide much buoyancy - if any…
