Have you ever wished you had a fully independent backup to your rebreather electronics? Perhaps you just want integrated decompression but don't want to rely on just one cell to prevent a debilitating bend. Cavers and extreme technical divers have long since known that when things go wrong, its best to have a solid backup plan.
