Here is a reminder about an update to the PADI TecRec Trimix course first detailed in the First Quarter 2010 Training Bulletin.
Although the diver manual and exam remained unchanged, an additional certification level—Tec 65—was added. PADI Tec Trimix Instructors may continue using the Tec Trimix Instructor Guides for both Tec 65 and Tec Trimix with an addendum (product no. 10166) that details the course changes and provides an additional Knowledge Development segment. Additionally, the update also altered the depth limits for individual training dive depths, specifically dives 5 – 8. The depths for each level are as follows:
Tec 65

| Dive One | None | 10 metres/30 feet |
| Dive Two | 27 metres/90 feet | 50 metres/165 feet |
| Dive Three | 30 metres/100 feet | 50 metres/165 feet |
| Dive Four | 40 metres/130 feet | 55 metres/185 feet |
| Dive Five | 45 metres/150 feet | 65 metres/210 feet |
