If using NAUI RGBM EAN32 dive tables, what is the maximum dive time for the second dive to 23 msw?

When using the NAUI RGBM EAN32 dive tables, it's important to follow the prescribed limits for dive times at specific depths. The second dive to a depth of 23 meters seawater (msw) requires consideration of both the first dive profile and the residual nitrogen from that dive.

The maximum allowable time for the second dive is determined by the need to stay within no-decompression limits while taking into account any nitrogen saturation from previous dives. For diving to 23 msw with an enriched air nitrox mix like EAN32, the dive tables indicate that the maximum no-decompression limit allows for a robust dive time based on the increased oxygen content and reduced nitrogen absorption.

In this case, the dive tables indicate that the maximum dive time for a second dive at that depth is indeed 47 minutes, as it optimally balances safety and bottom time. The selected dive times take into account the necessary considerations for allowing for surface intervals and residual nitrogen from previous dives. Adhering to these limits is essential to reduce the risk of decompression sickness during multiple dives.
