How should divers ascend if they are using a buddy system with no-stop limits?

When divers are using a buddy system and operating within no-stop limits, it is crucial for safety to adhere to the shortest no-stop limit within the buddy team. This means that the diver with the shortest no-stop limit dictates the ascent rate for the entire team. Ascending at the rate of the diver who can remain at depth the longest ensures that no member of the team breaches their no-stop limit, effectively minimizing the risk of decompression sickness.

This approach promotes teamwork and ensures that all divers are within safe limits, providing a unified ascent that prevents confusion. It also helps in managing potential gas narcosis effects or physical limitations that may affect divers' ascent rates. By sticking closely to the most restrictive limit on the team, all divers can ascend safely, maintaining equal safety considerations for everyone involved.
