Which factor is not generally included in the dive briefing?

During a dive briefing, the primary focus is on aspects that ensure the safety and success of the dive for all participants. Site conditions inform divers about environmental factors such as currents, visibility, and marine life, which are crucial for safety and planning. Dive objectives clarify what divers aim to accomplish during the dive, whether it's exploring a wreck, observing specific marine life, or training exercises, thus providing clear goals. Safety procedures outline protocols and emergency measures to keep divers safe throughout the experience.

Personal dive history, while important for individual safety and preparedness, is generally not discussed in the group briefing context. Each diver's experience level and past dive history are personal and can vary significantly, making it impractical to address in a briefing designed for the entire dive group. Instead, personal dive history is usually reviewed as part of pre-dive assessments between the instructor and the individual diver, ensuring that all safety measures are tailored to their skill level without taking time away from the group-focused briefing.
