Technical Diving

diverdown.gif

Technical diving could be called scuba diving’s “extreme sport”, taking experienced and qualified divers far deeper and further than mainstream recreational diving. Technical diving requires significantly more equipment and training requirements to manage the additional hazards of this type of diving. Tecnical diving isn’t for everyone, but for those who want to explore further, TecRec courses are the answer.

All classes offered by Cozumel Dive School follow PADI standards.

First, some important notes on Tec diving.

Technical scuba diving means going beyond recreational scuba diving limits and may include but not limited to one or more of the following: diving beyond depths of 40 meters/130 feet, required stage decompression, diving in an overhead environment beyond 40 linear meterss/130 linear feet of the surface, accelerated decompression and/or the use of different gas blends during the same dive, use of extensive equipment and technologies

 

In technical diving, the surface is often inaccessible in an emergency, so Tec divers use extensive procedures, equipment, and training to manage the added risks and potential hazards. PADI TecRec courses are the quality benchmarks in the Tec diving world due to their rigorous, yet logical, training sequence and the PADI educational materials that support them. Each of the three levels introduces you to new gear and procedures to extend your dive limits.
