INSIGHT FROM OUR DIVERS
What they say about us...
Annabel Jones Had a great experience with LBD doing our open water course highly recommend! Shoutout to Ernesto, amazing instructor!!! Holly Amazing experience doing the OW20. Shoutout to Ernesto, the best diving instructor ever Pierre-Yves Lapointe Be careful, if you decide to book your ow with this place, you’ll probably end up with some advanced class + extra fun dive days and good memories, it gets addictive 🤷â€â™‚ï¸ðŸ¤¿. Had a blast with Ernesto as our teacher 👌 Everyone at the reception is also very friendly. Alexander Fager We did the 1-day try dive with Nico, amazing instructor and so much fun! Definitely go here for courses or try dives! Nora Eckl Wir haben eine gute Einführung von dem instructor Max bekommen und konnten unsere Kleider anprobieren. Danach mussten wir 2 Stunden warten, bis das Schiff kam, was sehr unnötig war. Schließlich ging es los, wir haben vieles wiederholt. Als wir ins Wasser gingen, ist Max einzelt mit den Personen die Skills durchgegangen, er konnte mich gut beruhigen und war auch geduldig.Kira war auch dabei und war auch sehr hilfsbereit und hat genau so ein guten Job gemacht. War eine tolle Erfahrung, Danke nochmals. Ich dachte man bekommt unterwasser Bilder, war nicht der Fall. Luuk van Zilt Had a great dive with La Bombona. Thanks Kira and Max! Iñaki Urgoiti Con mi novia hicimos el curso Open Water 20 en LBD y estuvo espectacular! Nuestro instructor fue Roberto y nos encantó: super claro, muy dedicado y ante todo con muy buena onda. Disfrutamos un montón la experiencia y fue una excelente forma de introducirnos al buceo. Gracias! Sam Höjman Gjorde Open Water 20 och tyckte verkligen om det. Utbildningen var grundlig och välformulerad och min instruktör Ernesto var verkligen fantastisk och en höjdpunkt. De tar verkligen säkerhet pÃ¥ allvar och ser till att när du väl hamnat i vattnet sÃ¥ känner du dig bÃ¥de bekväm och säker. Kan starkt rekommendera att du tar ditt dykarcert här. Amy Pfitzner Did the open water 20 course with Ernesto, the course was absolutely incredible, highly recommend La Bomboba. Ernesto was a great instructor too - very experienced diver and made the experience very fun! Wish I could stay to do the advanced course. camila Saez Recomiendo a Ernesto como instructor, fue lo máximo!! Aprendà mucho y lo pase increible! La mejor disposicion para enseñar y es muy experimentado, apoyador y pasciente. Gracias!!!!
