What should divers do to improve their safety before a dive?

Researching and assessing the environmental conditions before a dive is crucial for ensuring a diver's safety. Understanding factors such as water temperature, current strength, visibility, and potential hazards in the dive site helps divers prepare adequately for the dive. By being aware of these conditions, divers can make informed decisions about dive gear, dive planning, and whether to proceed with the dive at all.

For instance, knowledge of water temperature is essential for determining whether a dry suit is necessary and for understanding the risks of hypothermia. Recognizing strong currents helps divers plan their entry and exit points effectively, while awareness of visibility conditions can influence their ascent and navigation techniques. Therefore, thorough research and assessment of the environmental conditions play a vital role in preventing accidents and ensuring a safe diving experience.
