“Excellent Service”

Dived with them in March this year (2014) while I was visiting St Maarten on a cruise.
Their dive times suite cruise visitors and give you time to travel across to the dive shop and sort your kit out before diving.
The staff are first class, the dives where very enjoyable, at a nice pace and in good waters.
If i ever go back to St Maarten (I have been twice already) I would defiantly dive with them again.

“A perfect day!”

We had a great excursion with Octopus Diving! They were courteous, and professional in every way. They told us about another couple taking the tour from a cruise ship and arranged for us to share a cab. Their boat was really nice – great shape and very clean! The first site we visited was Creole Rock. I snorkeled and my husband dove. The site was great, Sally and Dave were wonderful. Sally went through the dive instructions and equipment in great detail. They took the time to make sure we were comfortable before getting in the water. The other site we visited was Turtle reef, and this area was just beautiful! I saw lots of fish from the surface, and the reef was really cool. My husband also saw several fish, turtle, nurse shark, and Sally showed him all kinds of creatures (living and plants) on the ocean floor. We were really impressed with this company, and would highly recommend them.

“SCUBA at it’s best!”

Diving in SXM is fantastic, the water is clear and the reefs and aquatic life unreal. However, what makes it fantastic is the professionalism of the staff and owners at Octopus Diving. Friendly, courteous, knowledgeable and on spot to your every need. They are the ultimate dive shop, providing top notch instruction and certification, along with all the equipment needed for any dive. They really care about your diving experience…..JT is a great instructor, patient and understanding and willing do go the extra mile….Thanks for a great diving experience to all at OCTOPUS DIVING
