A powerful low piched buzz does all the work for you. All at the press of a button. The Sopras Sub Mini Acoustic Signaling Device has been engineered with efficiency and the highest priority.

To achieve the necessary power levels, the Sopras Sub Mini Acoustic Signaling Device utilises Power Valve Technology (PVT). The PVT is the heart of the system that synchronises the delivery of pressurised air to a reciprocating piston, cycling at 18,000 rpm. The PVT delivers snap-action control of compressed gas energy for an instant high powered acoustic signal with at absolute minimum air usage. The Sopras Sub Mini Acoustic Signaling Device is designed to last, with all high speed components, including the PVT system, machined from self lubricating, space age polymers, for light weight, low wear rate and long CORROSION FREE life – qualities that metal components simply cannot match. TheSopras Sub Mini Acoustic Signaling Device is also fitted with and acoustically optimised exhaust valve to protect against sediment intrusion.
