performed

TADPOLES continued Position

• Position relative to each other during the dive– Side by side

• Dive pattern

TADPOLES continued Out of Air

• Options– CESA– Octopus Ascent– Buddy Breathe– Positive buoyant

ascent– Bag breathing

TADPOLES continued Leader vs. Buddy

• Both divers should agree on the plan before the dive begins

• Leader role and responsibilities– Make decisions underwater that couldn’t be

• Do your own thing but support each other.

TADPOLES continuedSeparation Plan

Once separation is realized

• Designated searcher will search for one minute.

• Designated target will wait in place for 1 minute, while turning through 360 degrees and looking for bubble trail.

• If no contact, controlled ascent.

IMSAFE

IMSAFE is a pre-dive check of yourself and yourbuddy to make sure you are both mentally andphysically prepared to dive.

• I Illness• M Medication• S Stress• A Allergies/Alcohop• F Fatigue• E Environment/Equalize

“BASTED” Last minute Reminders

• Buoyancy

• Air

• Separation Contingency Plan

• Time

• Equalization

• Depth

Post Dive Activities

• Proper Hydration/Nutrition/Rest

• Keep activity to a minimum

• Stay awake and monitor for signs of DCS

• Adequate S.I.T. prior to flying

• Log dives

• Record data

Dive Log

• Record of experience

• Information available in the event of questions regarding DCS

• Information available for future dives

• Must be logged for scientific diving
