How many safety reels must a diver carry while cave diving?

In the context of cave diving, safety reels serve a critical purpose in ensuring divers can navigate safely and return to the entrance point without getting lost. Carrying at least two safety reels is advisable for several reasons.

Firstly, having a backup reel enhances redundancy; if one reel becomes tangled or malfunctions, the diver can rely on the second reel to ensure safe exit. This is particularly important in the challenging environments of caves, where divers may encounter restricted visibility, strong currents, or complex passages.

Secondly, safety reels facilitate effective navigation along the dive route. Divers can leave a guideline as they explore, which not only assists in retracing their steps but also helps guide any potential rescue divers if needed.

Armed with two reels, a diver can have one dedicated to the primary line followed into the cave and the second as a backup or for use in different sections or additional routes. This practice enhances safety protocols, reinforces good diving habits, and aligns with common diver training standards for cave diving, making it essential for a responsible diver to always be prepared.
