INSIGHT FROM OUR DIVERS
What they say about us...
EXCELLENT Based on 1156 reviews Posted on Victor Romero MateoTrustindex verifies that the original source of the review is Google. Hicimos un bautizo mi hermana y yo, fue increíble, tuvimos la suerte de tener a Carlo como instructor y lo bordo, un profesor 10/10 nos trató súper bien explico todo genial y nos ayudó en todo momento con cualquier cosa que necesitábamos, la verdad que una experiencia increíble en la bombona para repetir sin duda, todos los demás profesores y gente con la que compartimos la experiencia fueron super majos, si tenemos oportunidad repetiremos sin duda, experiencia totalmente recomendada!!!Posted on DAWN BARKANSTrustindex verifies that the original source of the review is Google. A Dream Realized. It is hard to put into words my thankfulness to LBD for helping me to achieve one of my lifetime goals/dreams. I did a TRY DIVE with instructor Sofia. Sofia guided me through the land, boat, and dive instruction. When I fell back into the water after donning my scuba gear, there was extreme excitement and as well as a terror. BUT Sofia was there with her calm voice and mannerisms coaching me. The first time I totally submerged, was overwhelming but I just kept looking at Sophia and following her calm hand signals. It was magic. If I started to feel panicked, I visually checked in with Sofia and all was well again. We did two dives. I felt strong, powerful, safe, and deeply humbled by the beauty of what lies below. I have no words Sofia for the gift of realizing a long term dream, and for realizing that age does not define me. I'm SO very thankful that Sofia introduced me to Jose, LBD Photo. Jose is a professional underwater photographer and he was also by my side taking photos of my dive as well as the beautiful underwater landscape. Friends and family that have seen the photos have said they are so vivid and was like being there with me. If opportunity presents itself, I highly recommend that you let Jose capture your LBD experience. Thank you Jose. Finally l, I would like to acknowledge the LBD, boat crew. They are the glue behind the scene, making everything run smooth and safe. Remember to respect our oceans Don't contribute to the trash epidemic in our oceans, that is even finding its way into paradise. There is vast life and beauty beneath the water that we need to protect. Again, thanks LBD, Sofia for helping me to fulfill my dream and Jose for capturing my experience.Posted on José Antonio Martínez BravoTrustindex verifies that the original source of the review is Google. Lugar insuperable, trato inmejorable e instalaciones inigualables.....in in in. Gracias por este día.....hay que repetirloPosted on Javier Medel GallegoTrustindex verifies that the original source of the review is Google. Magnífico día de buceo, grandes jóvenes profesionales con mucha experiencia. Todo muy cómodo y puntual. Repetimos seguro!!Posted on Paco records Jr.Trustindex verifies that the original source of the review is Google. Hubiera puesto 6🌟para esta maravilla de escuela e instructores!!Era mi bautismo y fue de las experiencias más mágicas y bonitas que pude tener….pero he decir que no hubiera sido probablemente lo mismo si no hubiera estado rodeado de magníficos profesionales y buenas personas!Nico mi instructor explicó todo genial tanto la parte teórica como la práctica y aunque fue en inglés porque yo era el único español del grupo, cualquier duda que me pudo surgir él estaba ahí para explicármelo las veces que hiciera falta,, fue muy amable y super enrollado! Cabe descartar que nos acompañó un gran fotógrafo para inmortalizar este precioso momento, él es José de Sevilla!vecino Andaluz , una bellísima persona también! un tío simpático y con arte por todos lados y como no un grandísimo fotógrafo, el tambien me asesoró en muchas dudas sobre la isla y me ayudó a que mi estancia fuera mejor! Muchas gracias! Y ya para rematar las chicas de recepción súper agradables y simpáticas, Rocio paisana y dueña de la escuela lo mismo! Un placer y espero volver pronto!Posted on Javier Planas LosadaTrustindex verifies that the original source of the review is Google. Fue genial bucear con La Bombona Diving. Me hicieron sentir super antes, durante y después del buceo. Centro serio, fuera del meollo del puerto y con barco de buceo. Divers pros y cercanos. Recomendable 100%Posted on ניתאי בודקTrustindex verifies that the original source of the review is Google. I have dived with Anna for the last 3 days. She was very very good and fun to dive with, I trusted her 100% and she is very professional and responsiblePosted on Squirrel SciuridaeTrustindex verifies that the original source of the review is Google. In one month on Koh Tao, La Bombona and instructor Paul got me through a nervous open water 20, a confident explorer 30, and academic nitrox certificates and many fun dives to marvel at the various underwater creatures. Prior to my diving journey, friends told me that finding a great dive shop makes all the difference, and I feel so lucky to have landed with La Bombona. The cheerful and competent attitudes of various instructors, divemasters, and boat crew made any good dive into a great joy, and I hope I come back someday very soon - for divemaster perhaps?Posted on Nicholas EngelTrustindex verifies that the original source of the review is Google. Did the open water 20 and we liked it so much that we added the explorer 30. The instructor Joy was great!Posted on Luca EngelTrustindex verifies that the original source of the review is Google. Had a great experience doing the Open Water 20 and Explorer 30 certifications. Joy was a great instructor and made the dives super enjoyable. We even saw a whale shark!
