A PATHWAY YOU CAN PLAN AHEAD

Combine Tec 40, Tec 45 and Tec 50 Training

Ask about planning Tec 40, Tec 45 and Tec 50 as one progressive training pathway. Training advances one level at a time, and each course’s prerequisites and certification requirements still apply. Tec 45 is required before progressing to Tec 50.

Practice sequence:

  • Start with Tec 40: Build your equipment, planning and team skills through workshops and four progressive dives.
  • Progress to Tec 45: Build on Tec 40 and meet the next level’s prerequisites before training for dives to 45 m / 150 ft.
  • Continue to Tec 50: Advance after Tec 45 to train for dives to 50 m / 165 ft and multi stop decompression.
  • Move forward level by level: Your instructor reviews your readiness, and each course’s requirements must be met for certification.
