[Seacidal]

I'm not sure where you read of that limit, but please bear in mind that the initial version of the product is intended for the recreational freediver, and not the competition apneist. However, the device does impose a maximum depth, based upon a number of variables, including the pressure and size of the compressed air cylinder. If you have only a partially filled cylinder, the device will calculate a maximum depth based upon the amount of buoyancy that is available from that partial fill. After all, what is the point of diving below a depth at which the safety device would be useful?
For competition apneists and that small percentage of freedivers who routinely dive to considerable depths (eg., beyond 130 fsw), different configurations are possible to retain the device's efficacy.
