About RED MERCS
Red Mercs is an exposed Mercury Islands boat dive with steep drop-offs, deep pinnacles, and kelp-broken rock around the island. It is the kind of place where current and swell matter as much as depth, and it rewards divers who are comfortable reading conditions, staying close to the skipper's plan, and working a more open-water style of terrain.

Local Intel For RED MERCS
Community notes to help plan your visit.
Scuba Diving
Keep the dive controlled and let the skipper pick the safest line to the reef before the current builds.
Freediving
Not a casual freedive site; the exposed outer edge and current make scuba the safer fit.
Snorkeling
Better as a boat scuba dive than a snorkel site because the exposed edge and changing conditions demand more room.
