Cave Diving Marker — durable, compact marker for clear underwater navigation Key benefits Durable construction: Made from ABS, this marker resists impact and repeated use for longlasting performance during cave and wreck dives. Compact and lightweight: Small, streamlined shape and low weight make it easy to carry, attach, and manipulate underwater without adding bulk. visible colors: Bright color options improve detectability in lowvisibility water so team members and you can find lines and markers quickly. Phosphorescent luminous feature: The marker absorbs ambient light and emits a glow in dark conditions, aiding orientation on penetration dives when light is limited. How it solves common diving problems Reduces navigation errors: Marks lines, turns, and exit points clearly so divers can retrace their route and avoid confusion in overhead environments. Improves team coordination: Visible, glowing markers help teammates locate agreed positions and shared lines during multiperson penetrations. Minimizes handling time: Lightweight, compact design makes placement and retrieval straightforward, reducing taskloading in confined spaces. Important attributes Material: ABS construction for strength and longevity. Function: Visual route marking and lowlight identification using bright colors and a luminous surface. Size and portability: Compact, easy to handle and transport; designed for underwater use without excess bulk. Compatibility: Suited for standard cave and wreck diving procedures where visual line markers are required. Practical use scenarios Cave penetration: Mark line intersections, turns, and midline staging points to ensure a clear route back to the exit. Wreck exploration: Identify entry/exits and maintain orientation inside wreck compartments where visibility and reference points are limited. Lowlight or night dives: Place markers at critical waypoints; the luminous surface helps divers relocate lines and anchors after lights are dimmed. What makes this marker stand out Combines a tough ABS body with bright coloration and a reliable luminous finish, offering a straightforward, lowmaintenance solution for underwater marking needs. Durable, visible, and easy to use — a practical tool for safer navigation in caves, wrecks, and other overhead environments.
