What is the hand signal for "Remaining Decompression Time"?

The hand signal for "Remaining Decompression Time" is accurately represented by tapping the dive computer, then making a fist with the little finger extended vertically. This signal effectively signifies to diving partners or instructors that the diver is actively checking their remaining decompression time, which is crucial for safe ascent and decompression procedures. The act of tapping the dive computer emphasizes the importance of confirming the dive profile and any necessary decompression stops, while extending the little finger vertically visually communicates the message about the specific aspect of the dive related to decompression. This clarity is vital in ensuring that all divers understand each other's status and can act appropriately to maintain safety throughout the dive.
