About Isurus Sub
Not all Mallorca dive operations shut down in October. Isurus Sub — full brand name ISURUS esport i aventura — runs from a year-round shop in Palma's Ponent neighbourhood, six days a week with no midday closure. The operation spans an SSI and PADI dive school, a filling station with two compressors (up to 300 bar, with urgent air service), an authorised repair workshop, and what the centre describes as the largest adventure-sports retail floor in Mallorca.
The centre holds SSI Instructor Training Center status — the highest tier in the SSI system — alongside PADI accreditation. Its most distinctive offering: a collaboration with Palma Aquarium that allows certified divers to enter the Gran Azul tank with qualified guides. Gran Azul is described as the deepest aquarium in Europe, housing more than 200 species including 20 sharks from four species. Boat dives operate separately, with the Isurus VI based at Port Adriano and running to the Marine Reserves of Illa del Toro and Illes Malgrats on the SW coast. Courses cover the full SSI and PADI recreational and technical range, including 20+ SSI specialties from Nitrox and Sidemount to Ecology and Mermaid.
The Club de Buceo y Aventura Isurus extends beyond the dive school with shore dives, Posidonia monitoring, coastal clean-ups, photography contests, and social events across the calendar year. The shop carries 50+ brands including Aqualung, Apeks, Cressi, Mares, Scubapro, and Suunto.
What Divers Say
Isurus Sub is consistently highly rated — a substantial review base for a city-centre dive shop. Direct community voice is limited, but YouTube footage from 2020 through 2024 shows organised, well-briefed boat trips at Isla del Toro. The SSI ITC designation, the year-round shop model, and a gear range uncommon outside major city retailers draw a clientele looking for a full-service centre rather than a resort-season package. The Club de Buceo's mix of monitoring, photography, and social events reflects an active local member community that extends well beyond the summer tourist circuit.

Frequently Asked Questions
What is the Palma Aquarium shark dive?▾
Through a collaboration with Palma Aquarium, Isurus Sub offers guided dives inside the Gran Azul tank — described as the deepest aquarium in Europe, housing 200+ species including 20 sharks from four species. The dive is conducted with qualified guides. Contact Isurus Sub for availability, minimum certification requirements, and current pricing. No other Balearic dive centre offers an equivalent experience.
Where does the dive boat operate?▾
The boat Isurus VI is based at Port Adriano on the SW coast of Mallorca. From there, dive excursions go to the Marine Reserves of Illa del Toro and Illes Malgrats — the headline SW-coast protected zone. Wreck dives, night dives, and half- and full-day excursions are also in the programme. Contact the shop or email buceo@isurussub.com for the current schedule and booking.
Is Isurus Sub open year-round?▾
Yes. The shop at Carrer Magalhaes 8, Palma is open Monday to Saturday 09:30-20:00, twelve months a year, with no midday closure. This makes it one of the few full-service dive centres in Mallorca accessible outside the summer season for equipment purchases, air fills, Nitrox, course training, and club activities.
What does SSI Instructor Training Center status mean?▾
An SSI ITC is the highest tier in the SSI centre classification. It authorises the centre to run the full SSI instructor development programme — training new dive instructors — in addition to all recreational and technical courses. The ITC designation requires a qualified SSI Course Director and ongoing quality monitoring. It's the same tier held by the largest SSI facilities in Europe.
Can I buy or rent diving equipment at the shop?▾
The retail floor stocks over 50 brands including Aqualung, Apeks, Cressi, Mares, Scubapro, Suunto, and GoPro — plus hiking, canyoning, surf, and swimming gear. Equipment rental sets number 100+, regularly inspected. The on-site filling station provides air to 300 bar and Nitrox, with an urgent fill service. An authorised repair workshop handles technical service for major brands, including official Bauer compressor service.
What is the Club de Buceo y Aventura Isurus?▾
The dive club runs year-round and extends activity well beyond the summer season. Programmes include shore dives, night-dive baptisms, Posidonia seagrass monitoring surveys, coastal clean-ups, underwater photography contests, underwater gymkhanas, and organised dive travel. The nature monitoring work connects to regional marine conservation programmes. Contact the centre for current membership details and the upcoming calendar.
