What is the maximum depth a buddy team can dive for 35 minutes if they end a surface interval as F divers?

The maximum depth a buddy team can dive for 35 minutes as "F" divers relates to the specific depth and time limits set forth in diving tables or dive computer algorithms. The classification of a diver as "F" indicates a certain level of experience and applicable no-decompression limits.

For "F" divers, while referencing the dive tables applicable to recreational diving, a depth of 60 feet allows for a 35-minute no-decompression limit, meaning that divers can stay for the full duration without the need for mandatory decompression stops during their ascent.

At greater depths, such as 70 feet or 80 feet, the time limits drop significantly for no-decompression diving. Therefore, engaging in a dive at those deeper levels for 35 minutes would exceed the safe limits and would require decompression stops, making 60 feet the maximum allowable depth for that duration under the given classification.

This understanding is vital for ensuring safety during a dive, and it emphasizes the importance of adhering to dive tables and no-decompression limits based on both depth and dive time.
