Dive Site Location & Key Facts
Everything you need to know about this dive site.
Dive Site Overview
The submerged topography here features a distinctive cylindrical structure, boasting a generous 13-meter (43 ft) diameter. Its central column plunges to a depth of 9 meters (30 ft), meticulously engineered for a wide array of underwater training exercises.
For more advanced or specific drills, a connected Single-Escape-Tower (SET) extends the maximum operational depth to 12 meters (39 ft), specifically designed for rigorous submarine escape and abandonment training simulations. Inside the main tower, the environment is meticulously structured. Divers will encounter three versatile folding platforms, strategically placed at a 5-meter (16 ft) depth, offering stable points for instructors to work with students on skill refinement.
A shallower platform is also present at 1.4 meters (5 ft), serving as an accessible entry point or a controlled area for initial practice. Beyond basic platforms, the tower incorporates elements like windows, car modules, and a 'preekstoel' (pulpit).
These features introduce realistic complexities for both recreational and professional diver education. Such a comprehensive design provides a professional, observable setting where divers can methodically develop and perfect their underwater proficiencies.
