Steve Cowley

JJ-CCR Level 1 Instructor

Steve Cowley is the owner and founder of Discover Diving.  Based on the Isle of Man in the Irish Sea, Discover Diving offers a fantastic range of diving opportunities and training from snorkelling, through recreational scuba and into technical diving. Steve co-ordinates a team of highly qualified and experienced instructors, many of whom have been trained in house. Discover Diving is a TDI Instructor Training Facility and a BSAC Centre of Excellence and has a proactive approach to diver development and progression.
Discover Diving was founded over a decade ago, when Steve became frustrated at the lack of support for technical diving in the region. Discover Diving now provides full service backup and support for all aspects of diving, especially technical. A purpose built hardboat supports technical dive trips around the deeper wrecks of the Irish Sea for visiting groups of divers.  Discover Diving holds dealerships for all main diving manufacturers and is the regional service centre for many brands of dive equipment. A fully equipped workshop including IDEST cylinder testing facility supports every level of diving.  Steve is also a qualified HSE Offshore Commercial diver and and has worked in a number of countries around the globe.
Steve has been diving since 1994 and took his first steps into technical diving a couple of years later. By 1998 Steve owned his first rebreather since then he has dived a variety of units including Sentinel, Inspiration/Evolution, Ouroboros, Drager, Azimuth, Poseidon and of course a JJ, and is a qualified instructor on most of them.  Steve qualified as a PADI Master Scuba Diver Trainer in 2005, TDI Instructor trainer in 2003 and a BSAC Instructor Trainer in 2004.  He enjoys teaching diving at any level.  Steve is qualified to teach CCR hypoxic trimix on the Inspiration/Evolution (up to and including instructor level) and Sentinel rebreathers.
Steve is one of those instructors who really understands the engineering of rebreathers and this comprehensive knowledge is obvious when he teaches.  Diving courses can be run on the Isle of Man, in the UK or indeed anywhere in the world. Previous training has taken place in the UK, Red Sea and the Canary Islands. Steve's attention to detail and encyclopaedic knowledge will help you get the best out of your training course.  As a highly experienced instructor, you can be sure that Steve will work with you to ensure you develop the skills and knowledge to take your diving further. Courses are run throughout the year and can be scheduled to suit.
