This certification aims to recognise dedicated SDI Instructors and provide new professionals with a clear milestone to strive for.

One key objective is to acknowledge the accomplishments of SDI Instructors while encouraging the growth of the next generation of diving professionals. This rating celebrates their achievements and is designed for active SDI instructors committed to producing skilled divers.

David Millin, Managing Director of Sea & Sea stated, “TDI is a legendary agency that UK divers and instructors have trusted for years to provide top notch training and quality materials. Sea & Sea is excited to be part of the continuing history”.

Brian Carney, President of International Training, acknowledged that the UK diving scene has an interesting history when it comes to TDI. The late Rob Palmer, a much respected cave explorer and a leading light in the fledgling technical diving community, helped set up TDI twenty years ago.
