No-decompression limits refer to the maximum allowable time a diver can spend at a particular depth without needing to make any decompression stops. This means that at any point during a dive, a diver can swim up to the surface without stopping, and this is also known as no-stop diving. However, it is crucial to remain within the given ascent rate defined by the dive.
No-decompression limits vary from dive to dive, depending on the depth. In diving, the no-decompression limit (NDL) represents the maximum bottom time for a given depth that a diver may stay without being required to make explicit decompression stops while surfacing. The no-stop limit is an estimate of the maximum amount of time a diver can dive to a given depth, assuming a square profile.
Scuba diving is always planned as no-stop diving, but safety precautions are made. Standard recreational diving is always planned as no-stop diving, but safety stops are made. Satety stops are considered mandatory on any dive deeper than 30m by most agencies.
In technical SCUBA diving terms, recreational diving is referred to as no-stop or no-deco diving. This means that as long as you are within the specified depth, you can safely dive without making any decompression stops.
In summary, no-decompression limits are essential for safe and efficient diving practices. They help ensure that divers can safely descend to the surface without stopping, reducing the risk of decompression sickness.
