Nortek support: How to set up and deploy the Signature ADCP buoy

The Signature buoy makes life easier for those working with the Signature250 and Signature500 ADCPs in the field. It is constructed from two identical halves, with internal pockets to fit the Signature250/500 and either a single or double battery canister.

Just four bolts are needed to hold the two halves together, and no screws or bolts are needed to keep the instrument and battery canister in place inside the buoy. The bottom part has a removable anchor plate with an arrangement that makes it very easy to attach the mooring rope.

The buoy is cylindrical with a slight conical shape. This means that the buoy will maintain a vertical orientation, even when exposed to strong currents and wave action, which is vital for good data.
