Team Diving vs Buddy Diving: How DIR Teams Work

Most divers learn the buddy system: stay close to one person and help each other if something goes wrong. It's a good rule. In practice, though, many buddy pairs are two divers who happen to be underwater at the same time, each following their own plan and checking on each other now and then.

Team diving asks for more, and gives more back. The team plans one dive, configures the same way, holds agreed positions and treats every diver's problem as the team's problem.

What is the difference between a buddy and a team?

UTD sums up the idea in its first covenant: the team is your backup for gas, equipment and brain. The second covenant adds the other half: no team member relies on another person or piece of equipment to make the sole decisions. No "trust me" dives.

How big should a dive team be?

Two or three divers. Three gives the team an extra set of eyes, an extra gas supply and an extra pair of hands, without becoming a crowd. UTD's dive-planning material sets a maximum of three divers on a team. If more people are diving together, split into separate teams, each with its own plan and leader.

Don't confuse team size with course ratios. A course may run with more students per instructor than a team has divers; in training, the instructor builds students into teams.

What roles does each diver have?

Every UTD dive plan names a leader: the person coordinating the dive. The briefing also assigns who leads the ascent and deploys the surface marker buoy; these jobs can be assigned separately, including a deco captain for the ascent.

The roles are interchangeable, and every diver should be comfortable in each of them. Rotate them from dive to dive so nobody becomes a passenger. Leading is a job, not a rank: the leader still answers to the plan, and anyone can call the dive.

How do teams position themselves underwater?

Position decides whether you can see a problem and reach it in time. Teams use a few basic formations:

• Side by side ("wing on wing"): the default in open water when visibility and space allow. Everyone can see everyone.
• Staggered: a looser version, with one diver slightly behind, useful when space narrows.
• Single file: for tight spaces, low visibility or overhead environments. A 7-foot long hose makes gas sharing in single file possible.

When something goes wrong, the team repositions. In a three-person team, the diver with the problem moves into the middle, where both teammates can watch and help. In a two-person team, the diver with the problem usually goes in front, where the other diver can see them.

How do dive teams communicate?

• Hand signals, held where your teammate is looking.
• Light signals, which work in daylight too if you carry a primary light. See Light Signals for Dive Teams.
• Touch contact, when visibility drops to nothing.

Every signal that asks a question needs an answer. If a teammate signals OK and you don't respond, they should treat that as a problem.

UTD's ninth covenant describes the attitude: manage the environment, the equipment and the team, giving equal attention to each. Head up, eyes open, brain on.

How does a team plan its gas?

Gas is planned for the team, not for each diver alone.

• Rock bottom is the gas reserve that lets two divers share one supply from the worst point of the dive to the surface or the next gas source. Every diver carries it.
• The team turns when the first diver reaches their turn pressure. If tanks or breathing rates differ, the plan follows the most limiting diver.
• Everyone states their numbers before the dive: starting pressure, turn pressure and rock bottom.

The details are in Gas Management for Recreational Divers.

What happens before the dive?

A team doesn't rely on a quick buddy check. It runs a short sequence that confirms the plan and the equipment:

• Plan review (GLADDDDD): goal, leader, gas, depth, duration, deco, direction and distance.
• Equipment match: everyone's configuration is the same, and everyone knows where everything is.
• In-water checks: a quick long-hose and valve check and a bubble check at the start of the descent.

See Pre-Dive Checks That Catch Real Problems.

What skills does a team practice?

The core team skills are the ones you hope never to need:

• Gas sharing with a long hose (the S-drill). See Out-of-Air Drill: How to Donate the Long Hose.
• Valve management, so a regulator or valve problem gets solved in seconds. See The Valve Drill Explained.
• Deploying an SMB as a team. See How to Deploy an SMB From Depth.

In UTD classes, gas sharing and SMB deployment are taught as team skills, not individual tricks. Each diver has a part to play, even when they aren't the one holding the regulator or the spool.

What if the team gets separated?

Agree the separation plan before the dive. In open water, the usual approach is short: look for your teammates for no more than about a minute, then make a safe, controlled ascent and regroup at the surface. Don't keep diving alone, and don't search until your gas is gone.

Good positioning and frequent checks make separation rare. Visibility, current, task loading and missed communication can all separate a team. Adjust position and workload before contact becomes unreliable.

Why does this make diving easier, not harder?

It sounds like more work. In practice, it takes work away. When everyone has the same equipment in the same place, nobody searches for anything. When the plan is stated out loud, nobody wonders when to turn. And when everyone expects problems, a problem becomes a routine instead of a surprise.

That's the core of the DIR approach, and of what UTD calls a thinking diver.
