Please congratulate Dawn Ostberg on successfully completing TDI’s Advanced Nitrox and Decompression Procedures courses! 🤿 We finished with two amazing dives to 150’, one at Crevice and then the deep wall at Sharks Pit.
She did a stellar job planning her bottom time, gas consumption, and then, in the water, executed the dive as planned with precise buoyancy control.
Well done, Dawn!
