TDI and ERDI Materials

These TDI and ERDI materials from International Training include manuals containing the latest published technical diving information. All have been designed and written to meet TDI's guidelines, reflecting the learning needs of today's divers. They include specially created illustrations and photographs in a perfect- bound format. The first thing readers will notice is that learning objectives and key concepts for each chapter are highlighted and clearly defined.

Some manuals also have an optional separate study pamphlet of related review questions that TDI calls a 'Knowledge Quest' and we offer the Knowledge Quest pamphlet when available.
