PADI® Open Water Diver is the first scuba certification level. A highly-trained PADI Instructor will teach you how to scuba dive in a relaxed, supportive learning environment.

By the end of the course, you'll have the skills and knowledge to dive at home or abroad and be an ambassador for the underwater world.


How to Earn your Scuba Diving Certification

Learn about scuba diving principles and terminology (either offline or online), then learn basic scuba skills in a pool (or pool-like environment) with a highly trained PADI Instructor. When you're ready, make four dives in an open water environment (the ocean, a lake) with your instructor supporting you every step of the way.

水肺潜水要求最低程度的健康和身体素质良好。 如果存在慢性健康不良状况,食用某些药物和/或近期手术可能需要你在潜水前获得医生的书面批准。

为避免失望,请下载并查看潜水员医疗健康调查表 Diver Medical From,以确保在注册水肺课程之前不需要获得医生的批准就能潜水。 教练,潜水长和潜店工作人员不是医师,不应征求他们的医疗意见; 只有医疗专业人员才能提供医疗许可以潜水。

如果你(或你的医生)对潜水的健康状况有疑问,请与Divers Alert Network(DAN)的专家联系。 


Course prerequisites: able to swim, medically fit for diving, comfortable in the water

During the Open Water Diver course, your instructor will ask you to:

  • Float or tread water without aids for 10 minutes
  • Swim 200 metres/yards with no aids or 300 metres/yards with mask, fins and snorkel

Minimum age: 10

Divers certified between the ages of 10-14 earn a Junior Diver certification

Junior Open Water Divers automatically become Open Water Divers at age 15. Any replacement certification card or eCard purchased the day after the diver's 15th birthday will automatically show an Open Water Diver (not Jr. Open Water Diver) certification.

Children eight or older can try scuba diving in a pool (or pool-like environment). Ask your PADI Dive Shop about a Bubblemaker experience or birthday party. Children who are comfortable in the water can participate in the PADI Seal Team program, a multi-day pool diving experience.


There are three parts to certification: knowledge development, skill practice, and open water dives. You can complete all three parts locally, on holiday, or split between the two.

Choose a dive shop close to home to:

  • Support your local diving community
  • Meet other divers in your area
  • Learn about your local ecosystem

Choose a dive shop away from home if you:

  • Plan to travel to a dive destination on holiday
  • Like to meet new people when travelling
  • Have the time to complete your course while on vacation

If you're not ready to try diving locally, but want to support your local dive shop, you can complete eLearning and portions of the course close to home, then complete the rest of the course while travelling. Contact your local PADI Dive Shop and ask about an open water referral.

TIP: Complete PADI Open Water eLearning before travel to minimize the amount of time you spend studying while on vacation.

This course requires both knowledge development and inwater training for certification. When you purchase a PADI eLearning course from our website, the cost covers the knowledge development portion only.

There will be an additional cost to complete your certification with a PADI Instructor. The cost depends on class size, location, and whether or not you need to rent equipment.

  • Most dive shops require students to provide their own mask, fins and snorkel. If you already own a mask, snorkel and/or fins, bring them to your instructor before your first inwater session. Some snorkeling masks and fins are inadequate for scuba diving.
  • Basic scuba gear, including a regulator, buoyancy control device (BCD), dive computer and cylinder, may or may not be included with the inwater training cost.
  • You may also need to buy or rent exposure protection (wetsuit or drysuit) depending on the diving environment.

Contact your PADI Dive Center or Resort for more information and pricing.
