What is the best practice regarding dive planning with nitrox?

The best practice regarding dive planning with nitrox is to plan dives within the limits of the specific gas used. This approach is crucial for ensuring diver safety and optimizing the benefits of using enriched air nitrox.

When diving with nitrox, divers must be aware of the maximum operating depth (MOD) for the specific blend they are using. By adhering to these limits, divers reduce the risk of oxygen toxicity, which can occur when the partial pressure of oxygen exceeds safe levels. Planning dives within the appropriate limits allows divers to manage their exposure to both nitrogen and oxygen, ensuring that they stay well within safe parameters.

Additionally, diving within these planned limits allows for more effective management of no-decompression limits, as nitrox typically allows for longer bottom times at shallower depths compared to air, given its reduced nitrogen content. This practice supports the overall safety and efficacy of diving with nitrox, helping divers enjoy longer and safer experiences underwater.

The other options do not prioritize safe and effective dive planning. Diving deeper than planned could significantly increase the risks associated with oxygen toxicity and nitrogen narcosis. Ignoring dive tables disregards essential safety guidelines and can lead to dangerous situations. Lastly, while using only one dive computer can simplify dive profiles, it is important to have
