About Nasonisoni Passage
Nasoninsoni is tailor- made for drift addicts who aren't afraid of the real thing. Don't plan on perusing the crinoids or fawning over the anemones on this dive and its not for sissies. The calm before the storm starts along the north wall until the drop off down to 50. There are plenty of hover-craft barracuda. When all of its two kilometres are done you can take stock of your pulse rate in a well-decorated protected inlet while enjoying the stillness of things.

Dive Site Hazards

  • Edge-Accelerated Currents — Currents often strengthen along drop-off edges.

  • Depth Perception Distortion — Visual contrast can distort perceived depth.

  • Terrain-Induced Descent — Divers may unintentionally follow terrain downward.

  • Hidden Depth Variations — Complex reef topography can conceal depth changes, leading to unintended profile variations.

  • Distraction from Marine Activity — High fish activity can distract divers and delay depth or gas awareness.

  • Rapid Surge Direction Changes — Surge near reef structures can reverse direction quickly, pushing divers sideways into unexpected areas.

  • Unstable Visual Ascents — Relying on wall visuals can destabilise ascents.

  • Gradual Depth Creep — Lack of visual bottom reference can cause unnoticed descent.

  • Unsignalled Downcurrents — Downcurrents can form without visible indicators.

  • Eddy Pull-Off Zones — Eddies behind structures can pull divers away from the main drift line.

  • Delayed Surface Pickup — Strong current can exceed surface tracking assumptions, delaying boat pickup.

  • Vertical Current Shear — Currents may vary by depth, causing vertical separation even when divers stay together.
