Astonishingly clear water. Just gorgeous.

I used to know some cave divers. Always thought it sounded cool, until they told me about taking off your BCD/tank and passing it through a gap because you wouldn't fit through while wearing it.

Nope nope nope nope.

Huge respect for these guys, you need to have your wits about you and have your shit together technically, but I'm not sure I could cope with that kinda claustrophobia.

Great photography. Remember there's a second diver floating out in the dark or following the main guy on camera.

Part and parcel to cave diving is controlling any dust/sand you kick up (basically: don't). The water is so clear, they've kicked up nothing. That's pretty pro.
