The APP is designed to work even in remote areas without Internet. Data transmission is based exclusively on light pulses. Even the login process (entering username and password) can be carried out without an internet connection.

No. The test description is only intended to give you a better understanding of how the sens07vest works. The sens07 head is designed so that it can be fully tested (tried out) in a bucket of water without a CO2 cylinder and without an actuator.

https://static.wixstatic.com/media/undefined The sens07 inflator immediately starts its auto-supervision of the user when water can be “sensed” by the inductive contact-free water sensors. When moving outside of the water, the sens07 inflator automatically goes into a power-saving mode consuming almost no energy. The sens07 inflator deliberately has no "power" button. It is always on so activation cannot be forgotten. However, it is possible to permit manual deactivation of the sens07 inflator. This option can be activated using the sens07 app if required by law (i.e. aircraft applications or special forces). However, we don't recommend to use this option and leave sens07 in automatic mode for ever. Please note that deactivating of the sen07 inflator doesn't save energy.

If the diver descends again before the "break time" has elapsed, then this dive is regarded as a continuation of the last dive and the dive time is continued and not reset. This mechanism prevents a diver from receiving the full dive time after a break that is too short or an accidental brief surfacing. This "break time" can only be cancelled by getting out of the water completely (sens07 inflator is out of the water for a few seconds). The sens07 button has no effect during the "break time".

For technical reasons, it is currently not possible to accurately measure depths below 30 metres, which means that such depths cannot be specified. If deeper dives are planned, the depth measurement can be switched off. However, the vast majority of accidents occur in the final phase of the ascent, or even immediately after surfacing. The dive time is therefore much more important than the maximum dive depth. We are working on an update which, in addition to a greater diving depth, will also include further safety functions.
