Factors Affecting Buoyancy

  • Body composition: Muscle sinks, fat floats
  • Wetsuit thickness: Thicker suits add buoyancy
  • Water salinity: Saltwater is more buoyant
  • Tank size: Affects weight distribution
  • Depth: Wetsuit compresses, losing buoyancy

Safety Tips

  • • Always do a buoyancy check in shallow water
  • • Start conservative and remove weight if needed
  • • Consider depth changes during your dive
  • • Account for wetsuit compression at depth
  • • Practice proper weighting with an instructor
