What our suppliers and clients say

Cressi recognised Didactic Turtle as the only 5* service centre in Portugal due to the capabilities shown by Eduardo and Manuel. Their approach to maintenance and the equipment they use is outstanding. Didactic Turtle will also be training our Cressi technicians for Portugal.

Poseidon works only with the best! When we discussed the Didactic Turtle project with Eduardo and Manuel, we saw that their know-how and experience were what we were looking for in a Service Centre and Rebreather Centre for Portugal. With their technical capabilities, we decided to extend the service coverage to military-grade equipment.

Sea & Sea Limited has worked with Eduardo for the past twenty years when he first established his regulator servicing. Eduardo’s attention to detail, focus, knowledge and experience place him as Sea & Sea Limited’s Instructor Trainer for DiveRite, Atomic Aquatics, Oceanic, Hollis, and Zeagle regulators for the UK and Ireland.

De Profundis is proud to recognise Didactic Turtle as our official service centre for the brands we distribute: Atomic Aquatics, Dive Rite, Zeagle and Poseidon. Eduardo and Manuel are trained to offer the best service in equipment maintenance, with an advanced facility equipped with the latest technology to provide excellent customer service.

Huish Outdoors and their existing Distribution partners in Spain and Portugal were looking for a Service Trainer to provide the best in customer support and service. After having Eduardo attending a Technician seminar, his experience and knowledge placed him as the perfect candidate to become our Trainer in that region for the brands we sell - Atomic, Hollis, Oceanic and Zeagle. After completing the Trainer course, and having worked before with Sea & Sea, Huish Outdoors Distributor for the UK, we decided to expand his coverage to the UK and Ireland market as well

When Eduardo contacted us to become a service technician for Portugal, we saw an opportunity to expand our service coverage in the region. However, after the completion of the training we saw that Eduardo's skills could be put to use in supporting Tecline Training technicians in the region. The decision was then taken to put Eduardo through our Trainer course.
