rareDive profile & how the dive runs
Diving at Blackie's Hole commences with a boat entry from one of the dive operators along Seven Mile Beach. The site's average depth is around 15 meters, guiding divers through a landscape rich with reef, canyon, and cave formations. A typical dive lasts approximately 60 minutes, allowing for thorough exploration of the site's unique topography. Divers will navigate through various coral structures and into open canyon spaces, maintaining the average depth. The dive concludes with a safety stop before ascending to the surface, where the boat will be waiting for pickup.
Underwater photography
Blackie's Hole's combination of reef, canyon, and cave structures presents diverse photographic opportunities. For capturing the broader landscape and unique formations, a wide-angle lens would be beneficial. Macro lenses can be employed to focus on the details of the very common sponges or less frequent smaller species like Pearl Blennies. Given the generally excellent visibility and moderate depths, natural light is often sufficient, but a strobe can enhance colors in the canyons and caves. Buoyancy control is paramount, especially when navigating confined spaces or near delicate corals, to avoid disturbing the environment and maintain clear shots. Always respect marine life by maintaining a safe distance and avoiding harassment.
