Yes, the possible failure points. A normal scuba outfit has few, perhaps only two compared to Avelo. This would be the BCD getting a hole and the inflator/deflator failing. In any case, the second one is more likely to be the inflator and you can still inflate by mouth.It is a phenomenal price for such a small benefit, especially using complex over-engineered technology.
Compared with 'standard' dive kit...
Pro:
- relatively constant buoyancy
Cons:
Have I missed anything?
- slow battery operated pump
- small variation in buoyancy
- proprietary carbon fibre cylinder and valves
- complex technology
- 300 bar gas required -- 50% greater than most recreational dive shops provide (for ali80s)
- slow fills to limit heat on carbon wrapped cylinder and bladder
- buoyancy training required to ensure correct weighting for user
- reliance on correct weighting on every dive: overweighting is a serious danger
- additional operator training
- limited pressure testing facilities to handle carbon fibre cylinders and proprietary equipment
- no additional surface buoyancy
- capital cost
- support availability
- flying rules (removal of cylinder valve)
- travel weight -- bring own cylinder and battery
- one dive only unless you bring two cylinders
The failure points as I see them for Avelo are; battery, pump, switch, bladder. So four real failure points compared to one relatively easy to overcome failure point.
Having seen people using this system in Sydney, I cannot see any advantage, since the size of the cylinder is 20% smaller than most people use so limits their bottom time proportionally. Certainly the price does not make it seem of any benefit at all.
