Recreational Scuba Dive Planning: Gas, Depth, Buddy and Conditions

Build a dive briefing around gas reserves, depth limits, navigation, emergency procedures, conditions and your personal experience.

Start with the site and the team
A useful dive plan reflects where you are diving and who is diving together. Discuss current conditions, entry and exit, likely navigation references, depth, water temperature and visibility. Agree whether all participants have the training, comfort and equipment for the site. A plan that depends on perfect conditions should be adjusted or postponed.

Set limits before entry
Identify your planned maximum depth, time and turn criteria within your certification and experience. Follow the applicable decompression and computer guidance taught in your training. Give yourself margins for environmental changes, slower movement or a buddy who needs additional assistance.

Agree on gas management
Check starting pressures and discuss how gas consumption and cylinder capacities affect the team’s plan. Establish turn and reserve limits using training-appropriate methods for the site and environment. A numeric turn pressure copied from someone else's dive may not be suitable for your cylinder, breathing rate or exit distance.

Review navigation and return
Discuss your intended route, compass or natural navigation references, and return procedure. Shore and boat dives can require different strategies. Confirm where you will surface, how you will identify the exit and how you will signal surface support when applicable.

Plan for a buddy separation
Agree on the lost-buddy procedure before the dive. Your training agency's procedures and the site briefing should guide what to do if visual contact is lost. Review how to communicate low gas, discomfort or an early end to the dive.

Identify reasons to call the dive
Unexpected current, worsening visibility, equipment problems, cold stress, stress or an uncertain exit are all reasons to reassess. Any diver should feel able to call the dive without pressure to continue. Following a plan includes recognizing when the original assumptions no longer hold.

Debrief and learn
Afterward, discuss what went well, what was different from the briefing and what should change next time. Record the information in your dive log or preferred app. Build skill through appropriate training and straightforward experience instead of treating quizzes or reading as substitutes for supervised practice.
