BlueZone offers the complete range of EdgeTech Acoustic releases.

The unique Push Off Release Transponder (PORT) is specified for many coastal water and shallow applications where biofouling is an issue. The unique push-off mechanism provides reliable release every time. The mechanical drive off system is the best choice for deployments where mechanisms can experience growth or sediment build-up.

BlueZone can assist you with the selection of the best EdgeTech release for your application. The following factors should be considered in the selection of an Acoustic Release:

• Depth Rating: Shallow water devices can be constructed from less costly plastics while deep water devices will require aluminium or titanium
• Load Rating: The Strongback or Heavy Load Release device can be used to increase lifting and release loads
• Frequency: Low frequencies give long ranges and robust communication. Medium frequencies are very reliable where vessel traffic noise is an issue.
• Deployment Period: Standard alkaline batteries can be replaced with lithium options for extended deployments
• Release Mechanism: The EdgeTech push-off mechanism provides reliable release when biofouling may be an issue

Specials and custom engineering is a specialty of EdgeTech and BlueZone engineers are also available to assist you with specialised designs incorporating acoustic releases, deployment frames, dataloggers, and other instruments.
