Conditions & Currents

Currents at Marker 42 Mansi are generally considered moderate, with an average probability of presence. Divers should anticipate potential drift along the reef walls, particularly when exploring the deeper sections and plateaus. Visibility at this isolated site typically ranges from good to excellent, often exceeding 30 meters, which is beneficial for spotting pelagic species in the blue. Water temperatures vary seasonally, from 26°C in winter months to 32°C in summer, making a 3-5mm wetsuit suitable for most of the year. Due to its exposure and the potential for pelagic encounters in open water, divers should maintain good buoyancy control and be prepared for deeper profiles.

Dive profile & how the dive runs

Your dive at Marker 42 Mansi typically begins with a descent close to the main coral column, often from a Zodiac. You'll follow the wall, which initially forms a coral belt sloping from 12 to 18 meters. This leads to a plateau at 25 meters, extending parallel to the wall for over fifty meters. From here, you’ll typically head southwest, keeping the wall to your right, until you reach a thriving forest of gorgonians at around 35 meters. This area is known for pelagic passages, with tuna and amberjack appearing from the blue. After exploring the gorgonian forest and watching for hammerhead schools, you'll gradually ascend, reversing your route along the wall. The return path leads back to the plateau, where numerous pinnacles, some detached from the main wall, create channels teeming with tropical fish and anemones. Your safety stop will be conducted at shallow depths along the reef, offering more opportunities for macro life observation.

Underwater photography

Marker 42 Mansi offers fantastic opportunities for both wide-angle and macro photography. For capturing the extensive gorgonian forests and the dramatic wall topography, a wide-angle lens is essential. Be prepared for blue water shots to capture passing pelagics like hammerheads and manta rays; patience is key as they emerge from the depths. Strobes are highly recommended to bring out the vibrant colors of the hard and soft corals, particularly in deeper sections. For macro subjects, search among the gorgonians for hawkfish and along the pinnacles for clownfish in anemones. Given the potential for moderate currents and deeper dives, excellent buoyancy control is crucial to avoid disturbing the delicate coral structures and to maintain stable shots.

Safety & environment

Diving at Marker 42 Mansi, given its depth and potential for currents, requires adherence to advanced diving protocols. Divers should be AOWD certified or equivalent and comfortable with deep dives and potential pelagic encounters. While specific details on the nearest recompression chamber are not consistently available, it is essential for divers to have comprehensive dive insurance that covers emergency medical treatment and evacuation. Saudi Arabia's dive infrastructure is still developing, making self-sufficiency and meticulous dive planning paramount. Always dive within your limits, monitor your air consumption, and ensure you have a surface marker buoy (SMB) for open-water ascents, especially when drift diving. Follow your dive guide's instructions closely, as conditions can change.
