Vertigo

The name describes the view: a wall that falls away beneath your fins into featureless blue while gray reef and blacktip sharks circle within arm's length. Operators have long used this corner of the western barrier for shark dives, and years of provisioning history mean the residents approach boats and divers with unnerving confidence — briefings cover hand positions for a reason. Even on quiet days a dozen sharks may attend, with dogtooth tuna and trevally cruising deeper. The clarity of the open Pacific gives the whole encounter a floodlit quality that channel dives on Yap cannot match.

वह पल जिसके लिए आप आते हैं: Gray reef and blacktip sharks at close quarters; exceptional outer-reef visibility; the sheer drop that named the site.

टोपोग्राफी: Steep outer-reef wall dropping from a shallow lip into deep blue water

करंट: Usually gentle on the wall; surge over the reef flat in swell.

प्रवेश: Outer-reef site near the northwest channel mouth; enter on the wall and settle along the lip.

खतरे: Bold, close-approaching sharks; an unforgiving drop-off for buoyancy lapses; surge on the lip in swell.

संरक्षण: Sharks here are habituated to boats — keep hands tucked, follow the guide's positioning, and let the animals set the distance.

Nitrox: यहाँ इसका फ़ायदा है — प्रोफ़ाइल उस रेंज में हैं जहाँ enriched air no-stop समय को सार्थक रूप से बढ़ाता है (इसके उपयोग के प्रशिक्षण के साथ)।
