INTRODUCTION This manual contains all the necessary contents required to participate in the PTRD Intro Diving program, certified with ISO 11121, equivalent to CMAS Introductory Diving and RSTC Introductory Scuba Experience. It has been written based on the guidelines of the EUF / ISO, CMAS and RSTC standards. Once you complete the theory and the immersion, or the dives, of trouble-free experience, your instructor could certify the PTRD Intro Diving level, which accredits you to: - Dive up to -12 mt without decompression and with the need for supervision of an Instructor but without having to repeat the theoretical part, - In places with conditions similar to where you have trained without the need for additional training, - During the day, - In places where vertical and direct surface ascent is possible, - With proper attention on the surface (people who can assist divers), - Using air. You could also participate in a complete diving course with the possibility of doing a less-than-planned practice in the chosen course. PTRD, in compliance with the most restrictive legislation, requires the participants of its courses the following prerequisites to its start: - Medical certificate indicating “suitable for diving”, or standardized medical self-declaration. - Photocopy of valid ID or passport. - Parental authorization for children under 18 years. - Minimum age 10 years (For younger ages we have other programs). - Fill in the student sheet and information about the risks. Your PTRD instructor (which must be at least PTRD 1 Star Instructor) must inform you in advance of the school's own requirements, price of your course, conditions for participation and completion of the course, as well as having at your disposal the documentation of your mandatory insurance "Civil Liability" and accidents. In addition to all the administrative documentation, you will need a specific equipment for the activity, which includes a diving bottle, weights, vest, regulator, suit, fins, mask, tube ... and that is normally provided by the school, or they must inform you previously in opposite case. Course Procedures: during the course, in addition to diving, we perform control and equipment management exercises and the training is integrated, which means that each exercise is related to the rest as a whole to make you go from not being a diver, to being it. The logical order of completion of
