Fiomarine’s Fiobuoy is a submersible all-in-one marine marker buoy designed to redefine safety and efficiency in marine navigation and underwater object retrieval. Developed to address critical challenges faced by maritime industries, enhancing both navigation safety and environmental preservation globally. The Fiobuoy is proudly developed and made by Fiomarine in Tasmania, Australia.
The Fiobuoy is an innovative piece of marine equipment that will conceal and secure underwater equipment, whilst simultaneously allowing for simple and safe retrieval. The Fiobuoys are manufactured as a complete product, with no need to source or fit separate components. Depending on the mission requirements, the Fiobuoy can be configured with a release and rope canister system or an off-the-self solution, saving both time and money.
Key Features:
Re-deploying the Fiobuoy is simple and can be accomplished shortly after recovery. Simply wind the rope back onto the device and program your desired release time and date, and your Fiobuoy is ready to go. To further streamline this process, Fiomarine offers a selection of rope winders for even quicker redeployment.
