- Be a PADI Tec 40 diver
- Be a PADI Rescue Diver
- Have a minimum of 50 logged dives, with at least 12 dives on enriched air nitrox deeper than 18 metres/60 feet and 6 dives deeper than 30 metres/100 feet
- Be at least 18 years old
- Have a Medical Statement signed by a physician within the last 12 months
Your Tec 45 training consists of three knowledge development sections, three practical application sessions and four open water dives.

You continue fine-tuning gas planning and calculating accelerated decompression stops. Plus, you learn to think like a technical diver.
