Progress Beyond Your Open Water Certification

Your Open Water certification provided the fundamental knowledge and skills required to dive to a maximum depth of 18 metres/60 feet.

The Advanced Open Water Diver course helps you develop your experience and learn to dive in a wider range of conditions.

Under the supervision of your instructor, you will improve your buoyancy, manage your depth, use a compass, navigate with natural references and complete a night dive.

You will also complete a dive between 24 and 30 metres/80 and 100 feet to progressively discover the specific considerations involved in deeper diving.

The objective is not simply to increase your maximum depth. This course is designed to help you become a more autonomous, precise and better-prepared diver.

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.
