Drumgrange Deliver Acoustic Hailing Devices to Japanese Coast Guard

Drumgrange is pleased to announce it has been successful in delivering a significant value contract to the Japanese Coast Guard. The contract, which was awarded in November 2013, was delivered to Tokyo, Japan on the 14th February 2014. This is a first for Drumgrange in the supply of AHDs to the Japanese market and was achieved with the enormous support of its Japanese partner, Marubun Corporation, a Tokyo based trading house. Drumgrange’s Acoustic Hailing Devices have been designed for high speech intelligibility at distances up to 1500m both on land and at sea, making them the ideal communicator for naval applications, commercial security, CBRN, merchant shipping, emergency services, oil & gas platforms and port & border protection.

George Howe, MD and Owner of Drumgrange, stated “The challenging project schedule made it imperative that the cooperation and communication between Marubun and my technical team was responsive, unambiguous and accurate, as a result the equipment was delivered to specification and ahead of time”.

The Acoustic Hailing Devices will aid the Japanese Coast Guard in their continuing efforts to patrol the country’s coastal waters and will provide much needed long range audio communications. Two types of AHD have been delivered; the four horn, AHD-9-14Z and two horn, AHD-5-12Z. These devices have a unique modular construction allowing for commonality of spares and single user assembly and operation.  The system can be removed from its case, assembled and fully functional in less than 15 minutes.
