The GUE Fundamentals course is designed to cultivate the essential skills required by all sound diving practice. Included among its course outcomes are: to provide the recreational diver, who does not desire further diver training, with an opportunity to advance his/her basic diving skills; to train divers in the theory and practice of Nitrox; to provide divers with aspirations for more advanced diver training with the tools that will contribute to a greater likelihood of success; and to provide non-GUE trained divers with a gateway into GUE training.

The GUE Fundamentals course isn’t an easy course, but it is an amazing learning opportunity and incredibly rewarding. 


I can offer the Fundamentals course in two different formats. Either four consecutive days or two very full weekends. The weekend course (termed Part 1 and Part 2) offers the advantage of being able to completed on the weekend, but it’s very possible that a third day will be needed for Part 2.


Japan based courses will take place at Osezaki and/or Atami (using Osekan Marine Service and Atami Scuba). These locations offer both good facilitates for running this type of course and protected diving spots so that we aren’t limited much by weather.

I also run Fundamentals courses in the Philippines - usually in Anilao, Batangas. Learning in the Philippines offers warmer waters so that you can use a wetsuit year-round. Please note that there will be extra travel and accommodation expenses when learning in the Philippines.


Japan based courses:

You will not want to commute to/from Yokohama or Tokyo for a Fundamentals course. I recommend these hotels, but you are welcome to stay anywhere in the same area.

For classes in Atami, the Toyoko Inn is clean and inexpensive. Be sure to book a few weeks before the class as this hotel does sell out most weekends.

For classes in Osezaki, you can stay at Osekan, the dive center we use. They have a traditional Japanese inn with tatami mats and futons. The cost is about ¥8000 per person per night (which includes breakfast). The other option for Osezaki is staying at a regular hotel in Numazu. I like the Cocochee Hotel and either of the two Toyoko Inns, but there are many to pick from. You will need a car to travel from Numazu to Osezaki (or arrange with me to share).

Philippines based courses:

Will be discussed. There are many options available to meet a variety of budgets.


Japan based courses:

It’s possible that I can help with transportation for the course in my car. Please let me know if that will be needed.

Philippines based courses:

Please arrange your own flights and transfers to/from the resort we are using.
