INTRODUCTION This manual contains all the necessary contents required to obtain the title of PTRD Extended Diver, equivalent to CMAS Extended Range Diver and ISO 11207. It is the first step to be able to do the technical diving programs.. It has been drafted based on the guidelines of the EUF/ISO, CMAS. This training programme aims at widening the experience gained since becoming an Advanced Nitrox diver through theory and techniques. This course will include training in accelerated decompression techniques. It will make candidates aware of the additional risks involved while undertaking this type of Diving. Once you have completed the theory and practice at sea, and passed the evaluation, your instructor will certify you as a PTRD Extended Range Diver as you will be considered to have a professional level knowledge of dive theory, solid technical skills, dive management and supervision skills, exemplary diving skills and sufficient experience to plan, organize and perform open water diving activities and organized dives in a safe and competent manner. A PTRD Extended Range Diver has specialized training and appropriate experience. A PTRD Extended Range Nitrox Diver shall be trained such that when assessed by a PTRD Instructor, he shall be deemed to have sufficient knowledge, skill and experience: • To plan, conduct, and log EANopen-water dives that can involve in-water, decompression stops using Nitrox mixes up to and including pure oxygen, when properly equipped with inservice oxygen clean Scuba and accompanied by a SCUBA diver of at lease equal training • To be aware of the additional risks attached to this type of diving and the use of pure oxygen • Able to undertake this type of diving at altitude depending on the National Federation rules • Be able to plan dives, select and use the correct mix and gas usage • Be able to demonstrate an understanding of depth discipline when using pure oxygen. The permitted depth is limited to a maximum of 56 meters (or to the maximum depth permitted by national standards) subject to a 1.4 pO2 for diving and 1.6 pO2 for stage stopsIf you are unable to successfully complete any of the sections, discuss with your instructor the options available, whether it is certification of a lower degree or the possibility of completing your course at another centre. Keep in mind that you will need additional training if you are going to dive to places whose conditions are very different from those of your training. For example, if you have done your course in a quiet area of the Caribbean in short 1mm suits, and then you are going to dive in cold water with strong currents using 7mm or dry suits,
