The regular tetrahedron offers geometric symmetry, ensuring that an upright triangular profile remains clearly visible from any direction, regardless of water movement or surface rotation.
The 0.9mm mesh-reinforced PVC is marine-grade and UV-resistant, engineered to withstand prolonged sun exposure, abrasion, and both saltwater and freshwater conditions.
The high-saturation purple provides exceptional contrast against open water, waves, and sky backdrops, ensuring navigation-grade visibility across various lighting conditions.
The marker measures 1.5m × 1.5m × 1.5m along each side of the regular tetrahedron, providing balanced surface area for high visibility while remaining manageable to deploy.
It is ideal for temporary waterway navigation, water operation zone demarcation, diving safety warnings, hydrological survey reference points, and film/TV aquatic production markers.
