Sharkbuoy Tough: GNSS Tides, Indestructible

Introducing the SharkBuoy Tough—our latest innovation designed for shorter deployments in the most challenging marine conditions. Building upon the trusted design of our original SharkBuoy, the Tough model eliminates the solar panel, which was the most exposed part of the original design. This buoy is not intended for long deployments but can handle rough treatment during deployment and recovery. Recharge in 3 hours and go again!

We've designed the Sharkbuoy with a focus on reliability, toughness, and ease of use. While enhancing durability by removing the solar panel, the SharkBuoy Tough retains all the mature and proven components from the original buoy, including Marinestar-enabled Septentrio GNSS, a tilt sensor, an Iridium modem, a programmable data logger, Wi-Fi connectivity, and a bullet-proof enclosure.

The newly developed Sharkbuoy Tough

(in production 2024)

Sharkbuoy tough...

Developed based on years of experience

The buoy can be attached directly to a mooring or, in high-current scenarios, a Norwegian buoy can be rigged to take any load off the Sharkbuoy's GNSS sensor (as shown). Every buoy comes with a 12kg counterweight chain that should always be used to maintain a constant buoy draft.

To ensure easy recovery via a grapple or hook, we recommend rigging the twin small floats at least 20m from the Sharkbuoy. For optimal performance, we suggest using a 15-25 kg anchor or 100kg clump weight (depending on currents and seabed type).

The Sharkbuoy can be ordered as a standalone unit or with a mooring system customized to the required water depth. Our buoy and mooring system are designed for easy recovery using a capstan or drum winch, with quick-release floats that enable the entire mainline and chain to pass through a wide block or onto a winch drum.

We have been through a few antennas in our time, that couldn't stand up to the conditions...the Tallysman Verostar 6037L exceptional build is the perfect match for Sharkbuoy

  • Rubber Bumper built for a tough life

  • Plastic coated base the only exposed metal is the connector

  • Stainless steel connector no corrosion issues here

Finally, an antenna tough enough for extreme conditions...
