Let’s Get Started!

Dive Instructor Training

After settling into your homestay close to the PADI Education Centre  - you will first be dive assessed and then start on the numerous dive qualifications you will be trained and tested on.

We take you from PADI Advanced Open Water, through Rescue Diver and Divemaster to become a globally approved PADI Dive Instructor. Even if you start with a more advanced qualification than PADI OW, it's always useful to refresh your skills. All divers are coached through night dives, rescue dives so you learn to become a fully qualified PADI Dive Instructor and PADI First Aid Trainer.

What you get in addition to a standard PADI Instructors Course:

Expedition Survival Training

1. Basic Jungle Survival Training Week: You will learn basic jungle survival training including how to navigate in the jungle, how to build your basha and cook food.

It's important you learn how to look after yourself so you are fit and healthy to lead. Therefore you will be trained and assessed on your health and hygiene skills, as well as jungle trekking, camp building and overnight survival skills.

2. Expedition Planning Week. From leading a corporate charity group, to teaching a school group to dive, whatever your career plan, we prepare you with team leadership training, how to plan and budget a program, problem solving and management skills. You will be assessed on your ability to safely lead your team in difficult conditions.

Leadership Training

Learn vital skills that are not part of a standard dive instructor course. You may go on to run your own dive resort shop, you may go on to lead TV crews in a marine environment, lead educational tours or gap year groups, whatever your plan we provide you with the skills to lead.

We train you how to work with clients, how to handle basic social media and digital marketing. International risk assessments and how to present them. In addition, we include core skills like boat handling and compressor maintenance. Learn with confidence to safely lead a successful dive program.
