Technical Diving

So, why Technical Diving?  Technical diving can offer more opportunities than regular recreational diving.  It can allow you to dive longer, deeper, use mixed diving gases, use rebreathers or go in overhead environments such as caves and wrecks.  These all sound fantastic (and are) but training is essential as all have further inherent risks if not conducted properly.  

Learning for technical diving will greatly expand your diving skills and knowledge and can provide you with experiences and exploration opportunities in places very few people will ever see.

Here at Wraysbury we currently offer the following courses:
