Technical Diving Training in Playa del Carmen

Technical diving goes beyond the usual limits of recreational diving through more advanced planning, redundant equipment configurations, multiple breathing gases and, depending on the course, mandatory decompression or the use of Trimix.

Becoming a technical diver is not simply about going deeper. Training focuses primarily on buoyancy, trim, propulsion, gas management, decompression, gas switches, teamwork and emergency procedures.

Exercises are introduced progressively and repeated until they can be performed with precision, stability and control.


Why Train in Technical Diving in Mexico?

Playa del Carmen and the Riviera Maya provide different environments for developing technical diving skills, including areas suitable for exercises, deeper dive sites, cenotes and locations where ascent and decompression procedures can be practiced.

Dive sites are selected according to the course, required depth, your experience, configuration, conditions and the objectives of each training session.

Frequently Asked Questions

What Level Do I Need to Start Technical Diving?

It depends on the course. Sidemount Diver allows you to develop a sidemount configuration from the earlier levels, while decompression, Technical Diver and Trimix courses require additional certifications and experience.

We review your level before defining the most appropriate training program.

Are Advanced Nitrox and Advanced EANx the Same Course?

Advanced Nitrox is a term commonly used by divers. The IANTD course name is Advanced EANx Diver.

How Deep Can I Go?

The depth limit depends on the certification. Advanced EANx Diver has a maximum training depth of 45 meters, Technical Diver 55 meters, and Normoxic Trimix Plus Diver a maximum certification depth of 75 meters.

These depths are maximum program limits, not targets that must necessarily be reached.

Can I Take a Technical Diving Course in Sidemount?

Yes. Sidemount can be used in several technical diving courses. The Technical Sidemount Diver course specifically focuses on using this configuration for technical and decompression diving.

Do I Need to Own My Equipment?

It depends on the course and your configuration. For advanced training, it is preferable to work with equipment you already know and can continue using after the course.

We review the required equipment with you before confirming the program.

Are the Courses Available in English?

Yes. Courses can be taught in English, French or Spanish.

Such an amazing cenote diving day with Halocline Explorers and Julien! 🤿 Two beautiful cenotes, super relaxed vibes, great gear and everything perfectly organized. We even had a nice lunch break between dives, which made the whole day feel easy and unhurried. Great dives, great vibes, great experience — would definitely dive with Julien again! 🤙🏽

J'ai eu le privilège de voir les prestations de Julien Garnier sous différents angles (en tamt que mère qui confie son enfant a un instructeur, en tant que cliente qui fait affaire avec un manager, en tant qu'élève moi-même et aussi en tamt que plongeuse technique confirmée). Julien est d'un professionnalisme exemplaire avec une patience d'ange. Pour ma fille et moi, il a su nous transmettre une parcelle de sa passion pour la plongée. Toujours avec le sourire, même sous l'eau, il enseigne de façon si fluide que même la plongée technique devient simple et la flottabilité un jeu d'enfant. Avec pour première priorité la sécurité de tous, il transmet avec générosité ses connaissances bien au delà des requis d'une formation. Julien, mon ami, merci! Que ce soit pour une première rencontre avec un détendeur ou pour un rêve de devenir plongeur technique, avec Julien Garnier, vous pouvez vous lancer dans l'aventure les yeux fermés (ou avec un couvre masque).

J'ai plongé 2 X avec Julien Garnier aux Bahamas. C'est un excellent moniteur qui vous met en confiance, très patient et attentionné. Avec lui, je n’aurais pas peur de plonger dans des grottes ou endroits improbables, car il est particulièrement expérimenté et responsable. Chantal Lepers, advanced PADI, 141 plongées.

Une super expérience de plongée avec Julien qui m'a ouvert les portes de la plongée technique. Un grand passionné et un très bon technicien qui est, en plus, très sympa! Donc si vous cherchez un très bon instructeur compétent et carré, n'hésitez pas. Moi, j'y retournerai pour me lancer en recycleur! Merci Juju!

Tuve el privilegio de realizar con Halo Explorer (Julien Garnier) tanto mi certificación Open Water como mi certificación Advanced Open Water. A lo largo de toda la formación Julien Garnier ( Divemaster/ Instructor de buceo) demostró un alto nivel de profesionalismo, conocimientos técnicos sólidos y un compromiso constante con la seguridad. Su capacidad para explicar conceptos complejos de manera clara y adaptarse al ritmo de aprendizaje de cada estudiante hizo que la experiencia fuera sumamente enriquecedora y eficaz. Además de su excelencia técnica, destaca por su calma, paciencia y liderazgo bajo el agua, cualidades que inspiran confianza y permiten desarrollar las habilidades necesarias para bucear con seguridad y autonomía. Gracias a su dedicación y calidad de enseñanza, completé ambas certificaciones sintiéndome preparada, segura y motivada para continuar avanzando en el mundo del buceo. Recomiendo los servicios de Halo Explorer sin ninguna reserva a quienes busquen una formación de alta calidad impartida por un instructor y divemaster verdaderamente profesional.
