Tec diving
Where recreational
diving ends.
Depth beyond 40 m, planned decompression, mixed gases and overhead environments. It is a different kind of diving: slower, more planning, more gear, and no rushing to the surface if something goes wrong.
What tec diving actually means
- You dive with redundancy: two of everything that matters, because you cannot simply ascend.
- You plan the dive before you get in, and you dive the plan — gas, depth, time and stops are decided on land.
- Decompression stops are mandatory, not optional. The surface stops being an escape route.
- Mixed gases replace air: nitrox blends for the stops, trimix when depth makes nitrogen and oxygen a problem.
The gear it takes
Sidemount or twin tanks
Two independent gas supplies, each with its own regulator.
Stage and deco bottles
Carried separately for the decompression stops.
Redundant lights
A primary and at least two backups in any overhead environment.
Reels, lines and markers
To find the way out and to mark your position from depth.
The training
Tec courses are priced per programme: the gas, the number of dives and the gear all change the cost. Tell us your level and what you want to reach and we quote it.
Tec Sidemount
Twin tanks at your sides instead of on your back, for passages a back-mounted tank will not fit through. The entry point to cave and wreck penetration.
Requires · Advanced Open Water and good buoyancy control
Intro to Cave
Beyond daylight, on the main line, with the gas rules and the drills that make a cave dive survivable. The minimum we ask for cave dives.
Requires · Cavern certification
Full Cave
Jumps, gaps and complex navigation. The level that opens the technical systems: Taína, Jardín Oriental, El Toro.
Requires · Intro to Cave
Technical cave programmes
Advanced cave, stage and multi-stage diving, and rebreather cave work, planned around what you already hold.
Requires · Full Cave and logged cave dives
Before you write to us
- Your current certifications, and which agency issued them
- How many dives you have logged, and how many in the last twelve months
- Your own gear, if you are bringing any
- What you want to dive while you are here
What you will see.
The kit you dive with
XDEEP ZEOS, at no extra cost.
Complimentary use of the industry-leading XDEEP ZEOS gear with any diving service you book. Most centres charge extra for equipment like this: here you dive with the same kit we would take down ourselves.
XDEEP ZEOS
IncludedBackplate-and-wing BCD. Stable in trim, and it holds you level instead of tipping you upright.
XDEEP Sidemount
US$ 25 per two divesFor cave and wreck penetration, where a single tank on your back will not fit through. It carries two regulators, so it is the one piece of kit we charge for.
Full standard kit
IncludedTank, weights, regulator, mask and fins, serviced and checked before every departure.
Bring only your swimsuit. Tell us your size when you book and it will be ready on the boat.

Questions we get
every single day.
If yours is not here, ask us on WhatsApp — we answer in minutes, not days.
For the dive packages, yes — they are built for certified divers. If you have never dived, start with the Discover Scuba Diving course: a short theory session, a practice in confined water, and then a guided dive with an instructor beside you the whole time. Tell us your level when you write and we will point you to the right one.
The certified guide, private transport from your hotel, and the full diving equipment — tank, weights, regulator, BCD, mask and fins, including the XDEEP ZEOS gear at no extra cost (sidemount and twins are US$ 25 per two dives). Courses also include the SSI digital materials and all certification fees. Food and drinks are not included except on the island trips, which come with buffet lunch.
Yes. Private transport is included in every package. Tell us the name of your hotel and your arrival date when you book, and we agree a pick-up time that fits your day.
Two dives per day, morning and after a surface interval, so a 6 Dive Package runs across three days and a course is spread the same way. Packages are personal and non-transferable, and the dives can be spread over your stay — tell us your dates and we plan them with you.
Bayahibe is where the diving happens, and it is not only reef. We run cargo wrecks resting upright — St. George, Atlantic Princess, Monica — reefs like Aquarium and Turtle Reef, and flooded cave systems such as Padre Nuestro and Chicho, which few centres are certified to guide. What you dive depends on your level and the conditions that day.
Two or three days is usually enough, and in high season a week gives us more room to plan. If you are already here, message us anyway — we often have space the next morning.
Safety comes first: if sea conditions are not right we move the dive to another day of your stay, or refund it if that is not possible. We decide in the morning and tell you as early as we can so it does not ruin your day.
The minimum age is 10 for the introductory dive and 12 for certification courses. You will fill in a standard medical questionnaire; some conditions (heart, lungs, ears, pregnancy) need a doctor to sign off. Tell us in advance and we will walk you through it.
Italo, SSI Instructor Trainer and IANTD Technical Cave Instructor. He runs the centre himself and guides every dive, so you get the same instructor from the first briefing to the last ascent.
