Which of the following is NOT a benefit of diving with Nitrox?

Diving with Nitrox offers several advantages primarily related to the reduction of nitrogen exposure and the potential for longer dive times. The benefits include longer bottom times at specific depths due to the reduced percentage of nitrogen in the gas mixture, which indeed allows divers to stay underwater longer while managing the risks of nitrogen narcosis and decompression sickness more effectively.

Reduced nitrogen absorption is another significant advantage. When using Nitrox, which has a lower nitrogen content than standard air, divers absorb less nitrogen during their time underwater. This leads to a reduced risk of decompression sickness, as there's less nitrogen to off-gas upon ascending.

Shorter surface intervals between dives can also be a benefit when using Nitrox. Because divers experience less nitrogen absorption, they may find that their surface interval requirements are decreased, allowing for more dives in a single day or minimizing the waiting time between dives.

On the other hand, enhanced buoyancy control is not directly a benefit of diving with Nitrox. Buoyancy control is primarily influenced by factors such as the diver's equipment, body composition, and the amount of weight carried. While Nitrox can impact a diver's experience, it does not inherently change buoyancy control, which relies more on the diver's physical ability and equipment settings
