Professional Diving Services share their sadness as with all of the Denso staff internationally in the recent passing of its company chairman and good friend, David Winn. PDS have enjoyed a long friendship with David and we will greatly miss his annual visits and the time we got to spend with him in Australia and abroad. David joined the family business of Winn & Coales in 1965 and served as chairman of Winn & Coales International Ltd for the last 29 years. David was the third chairman appointed to the company in its much celebrated 137 year trading history.
