Tec 45 Diver

PADI Tec 45 course provides a transitional qualification while continuing to develop as a technical diver. The equipment requirements are the same as for the Tec Deep Diver Course.

This diver is qualified to make limited technical decompression dives using the equipment and the procedures used at the Tec Deep Diver level. However, qualifications are narrow, reflecting comparatively limited training and experience. The expectation is that a Tec 45 diver plans to continue on to Tec 50.
