TDI CCR AIR DILUENTDIVER COURSE

服務說明

The TDI Closed Circuit Rebreather (CCR) Air Diluent Diver Course is your first step into closed circuit rebreather diving and your first truly quiet dive experience!Using the latest technology in CCRs can maximize your gas supply and provide an optimum breathing gas for any depth by maintaining a constant partial pressure of oxygen. It’s like having a nitrox blending machine on your back! During this course, your TDI Instructor will teach you all of the necessary skills to conduct no decompression CCR dives to a maximum depth of 30 metres/100 feet using air diluent. Rebreather Course prerequisites: • Minimum age 18 • Provide proof of 20 logged open water dives • Provide proof as a TDI Nitrox Diver or equivalent from agencies recognized by TDI Some of the required skills you will have to demonstrate include all of the following and more: • All open water dives must be between 9 metres/30 feet and 30 metres/100 feet • Two dives must be deeper than 20 metres/50 feet and one dive must be deeper than 27 metres/90 feet • Partial pressure of oxygen not to exceed manufacturers recommendation or a working limit of 1.3 • All dives to be completed within CNS percentage limits with a recommend maximum of 80 percent of the total CNS limit • Where the user opts for an automatic diluent valve (ADV) fitted and approved by the manufacturer, additional skills such as regular diluent gauge monitoring and addition control must be emphasized • Unit build up and break down • Predive checks • Verify diluent and oxygen contents using an analyzer • Demonstrate correct predive planning procedures • Cover emergency procedures • Use of BCD/dry suit and effective management of loop breathing volume for buoyancy control • Stop at 13-6 metres/ 10-20 feet on descent for leak/bubble check • Electronic system monitoring for partial pressure of oxygen levels (set point) and switching set points • Use of lift bag, or surface marker buoy and reel, where appropriate • Proper execution of the dive within all pre-determined limits • Demonstration of safety stops at pre-determined depths • Constant loop volume management • Post dive clean of unit • Diver maintenance of unit
