Cave Diving Cookie – Customizable 3D Printed Line Marker

Designed for experienced overhead-environment divers, this cave diving cookie is a precision 3D-printed line marker used as a navigation reference—or “breadcrumb”—to help divers safely find their way back to the exit. Compact, lightweight, and easy to deploy, it’s a trusted tool for cave, cavern, and technical diving.

The clean circular design allows the cookie to sit securely on guideline without rotating, while the cut-through slots ensure reliable placement and removal even with thick gloves. Each cookie can be customized or personalized, making it easy to identify your markers during complex dives, shared systems, or team operations.
