The "Level Off" Hand Signal
The "Level Off" hand signal for scuba diving is use to communicate "remain at this depth" or "maintain this depth." The "Level Off" signal is most commonly used to communicate that divers have reached the planned maximum depth for a dive, or to communicate that divers should hold previously designated depth for a safety or decompression stop. The "Level Off" hand signal is made by extending a flattened hand, palm down, and slowly moving it side-to-side horizontally.
