Since the introduction of the closed circuit rebreather to mainstream diving in the early 90’s, it doesn’t appear to have lived up to the hype. There are a number reasons which can explain this. The equipment is expensive and so is the training when you consider the diving hours required to become proficient on these units. There have also been issues with the reliability of cells and complex electronics when mixed with water. These are factors which have made the inevitable rise of the machine slower. But you can’t stop progression and eventually more and more diving schools and facilities will offer rebreather training as standard.
Rebreather diving at DJL
At Davy Jones Locker we are rebreather friendly with 2 and 3 litre tanks available for rent. We also offer booster pumps for pushing up the o2 pressures needed for deeper dives and extensive training. The agencies we work with are ANDI and IANTD. In the future PADI/DSAT certification will be provided for the inspiration classic/evolution vision electronics.
The main reasons for choosing these units to concentrate our training on are the cost, availability and excellent support from AP Valves. The inspiration/evolution units are the most popular units on the market and have more dives completed on them than any other unit. They are constantly evolving and have many unique trademarked features. The cost is also very competitive with a very healthy second hand market. Some inspiration classic units change hands for as little as £600.
We’re not claiming that these units are the Ferraris of rebreather systems. Top end units like the JJ or Megalodon come with a hefty price tag of £7000. As a result, a student wishing to train on one of these would have to find around £8000 just to be able to practice after completing the course. The Inspiration/Evolution unit sits comfortably in the VW Beetle category. Reliable and low cost with a healthy second hand market. Furthermore, this can enable a student, after paying around £1000 for their course, to continue diving for as little as £600 for their own unit.
These units are rated to 100 m and with some modifications can increase this to 150 m. This gives plenty of scope for experiencing dive exploration and becoming part of the rise of the machine.
