PADI Discover the Explorer Rebreather ( Open Water )

An introduction to Scuba Diving with the Hollis Explorer Rebreather!

The Hollis Explorer Rebreather is widely recognised as the future of Scuba Diving. Divers curious to experience closed circuit diving can do so in a confined open-water dive, giving you practical experience of using the Rebreather in the Sea. You'll get to find out what it's like to breather underwater without bubbles, hover effortlessly without much effort and what Rebreathers can offer you as a diver. This is a superb introduction to Rebreather diving that allows you to try it first-hand in a safe, confined open-water dive. We also offer this experience in a Confined Pool scenario, allowing you to experience Rebreather diving in an indoor pool environment to ease yourself into the world of Rebreather diving.

What is included in the Discover the Hollis Explorer experience?

  • First stop is the classroom, where one of our instructors will teach the appropriate theory for the session and then check your understanding with a knowledge review.
  • Then comes the fun part, an hour long Dive at one of our regular teaching locations where you'll experience diving with the Hollis Explorer Rebreather at sea, safe in the knowledge that our instructor is on hand right by your side..
  • After your classroom and confined open-water dive, you'll be one step close to becoming a PADI Rebreather diver.

Knowledge Development

Your instructor will explain and you will learn the operation, function and diving procedures of the Hollis Explorer Rebreather.

At the end of the course you'll have a first-hand understanding of the Hollis Explorer Rebreather, it's functions, basic assembly and operation.


Divers wishing to book a Rebreather Experience should check that the following checklist is applicable.


For safety, all students must complete a brief Scuba Medical Questionnaire that asks about medical conditions that could interfere with diving. Simply complete the form and if nothing applies to you, you're ready to dive. If however any of the questions do apply to you, as a safety precaution your Doctor must assess the condition and sign a medical form that confirms that you are fit to dive.

Discover Rebreathers and Beyond!

Once you have completed your PADI Discover Rebreather course, you can then progress onto the PADI Rebreather Course. Don't forget that an optional Confined Pool Experience is still available at this point giving you multiple chances to experience the Hollis Explorer in varying conditions to make sure that this is the right unit for you! Alternatively, if you're looking to dive deeper, then consider the PADI Deep Diver Speciality, taking you to the depths of 40m on open circuit, which can be converted over to Rebreather during the Advanced Rebreather Training.

Alternatively, now you have bubble free, silent diving the fish life around you in the sea will be more abundant, so why not take advantage of this with the PADI Digital Underwater Photography Speciality, and take pictures that Open circuit divers can only dream of!
