Dos Tiburones runs two boats out of downtown Cozumel with a hard cap of eight divers per guide and a standing 1:4 ratio on training dives. Every trip includes nitrox, marine park fees, and tank service.
The shop is a PADI 5 Star Instructor Development Center and an SSI Diamond facility, so training runs from Discover Scuba through Divemaster on either agency. The on-site pool means confined water sessions never depend on boat traffic or weather.

The ratio is not marketing
Four of us to one guide, every dive. Ana spotted a toadfish, two eagle rays, and a splendid amount of patience with my buoyancy on day one.
Danielle R. · Austin, TX · March 2026
Nitrox included made the week
Five days, ten dives, no surcharges and no upsell. German-speaking instructor was a bonus I did not expect.
Marcus L. · Hamburg, DE · February 2026
Great diving, busy shop
The morning boat gets full in high season. Book the second boat if you want a quieter trip. Diving itself was flawless.
Priya S. · Toronto, CA · January 2026
Questions and policies
Do you require a check dive?
Not for certified divers with a logged dive in the last 12 months. If it has been longer we add a shallow refresher on the house reef at no charge before your first boat trip.
Can I bring gear I rented somewhere else?
Yes. We only ask that regulators serviced more than 12 months ago get a bench check, and we cannot fill cylinders we have not visually inspected.
Is nitrox really included?
Yes, on every boat trip for certified nitrox divers. Marine park fees and tank service are included as well.
Do you pick up from hotels?
Free pickup along the hotel zone and downtown. Southern all-inclusives are a $10 flat shuttle.
What happens if the port closes?
Winter north winds close the port a handful of days each season. We move to shore diving or reschedule, and unused boat days are refunded in full.
