Acoustic Warning and Notification System "REV-A" for Underwater Divers - Ensuring Safety in Protected Areas

The REV-A system is designed to warn and alert underwater swimmers on fins and underwater swimmers on means of propulsion:
- in the water areas of protected objects, by emitting speech warning and alerting signals into the aquatic environment
- warning and alerting by emitting sound signals.
FEATURES:
- In the "Tone" mode, a sinusoidal signal of the highest power is emitted, with a frequency close to the frequency of the highest sensitivity of the human hearing aid in water
- In the "LFM" mode, the sensation of discomfort is created by changing the frequency of the sound over time (modulation).
- Can be used without special authorisation
The complex includes:
- radiating antenna
- surface control unit
- power supply cable
- microphone
- antenna extension cable
- antenna cable with carabiners
