Underworld offers a wide range of recreational, technical and cave training – everything from a Try Dive through to advanced cave, trimix or closed circuit rebreather courses. Our instructors have trained and instructed with numerous agencies and experienced a huge range of diving conditions around the world.

We aim to use the best aspects of all the agencies we have experienced, whilst remaining within the standards of the certifying agency. These are the things that make Underworld training stand out:

– Training at your pace. We don’t rush training and our recreational courses are longer than the industry standard to make sure our divers are confident, competent and enjoy the experience!

– No hidden extras. All our courses include entrance fees, course materials, certification costs, cenote entrance/boat fees, transport, equipment rental and lunch.

– All technical training is quoted per day, and we do not require a deposit in advance. We don’t quote for a fixed price for courses as we remain flexible during your training with us. It’s much better to provide an invoice at the end of your stay based on the number of days you dived. We understand that circumstances change, so you might need days off for sore ears, jetlag, mental capacity etc, so our calendars are flexible to work for you.

– Top quality equipment. We only rent equipment that we are happy to use in our own diving, so our students will be using some of the best available, including Apeks regulators, Halcyon lights and wing systems, and Fourth Element wetsuits.

– Nitrox as standard. All our courses are conducted with Nitrox at no additional cost, except where agency standards forbid this. If you are not Nitrox trained we can offer discounted Nitrox training as part of any other course.
