What is not a major consideration in a dive plan?

In a dive plan, the "exact underwater terrain" is not considered a major factor compared to the other components. While understanding the underwater terrain can certainly provide context and enhance the safety and effectiveness of the dive, it is not as critical as the fundamental elements like the dive goals, potential hazards, and communication procedures.

The goals for the dive help to define the purpose and objectives of the operation, ensuring that all team members understand the mission. Identifying potential hazards is essential for planning, as it allows divers to prepare adequately and implement risk mitigation strategies. Communication procedures are critical for coordinating actions among divers and ensuring safety throughout the dive, facilitating timely responses to any issues that may arise.

Thus, while the terrain may influence how a dive is executed, it does not hold the same level of priority in the planning process as other key factors do.
