What is the single depth limit for 35 fsw?

• A. 25 minutes
• B. 15 minutes
• C. 240 minutes
• D. 80 minutes

Answer: (A)

The question tests understanding of the no-decompression limit at a given depth—the maximum bottom time you can stay at that depth on a single dive without needing decompression stops. At 35 feet of seawater (about 11 meters), the dive tables used in this course list a no-deco limit of 25 minutes. This means you can remain at that depth up to 25 minutes and then ascend directly to the surface without decompression stops. The limit exists because nitrogen absorption into your tissues increases with depth, so deeper dives require shorter bottom times to avoid decompression requirements. If you stayed down longer than 25 minutes, you’d be in a decompression-zone and would need staged stops or a different plan. The other options either underestimate the maximum bottom time or exceed the no-deco window for that depth, which is why 25 minutes is the best choice.
