Proper ballast weight is essential to prevent buoy overturning. Carefully consider the site-specific ballast requirements prior to deployment.
A 25 lb. ballast weight is available for installation to the bottom of the instrument cage for additional balance.
1. Begin installation by inserting the 9-3/4” threaded rod section through the ballast weight and bottom of the buoy frame or instrument cage assembly.
2. On the bottom end of the rod, tighten a 1-3/4” eye nut with a 1-3/4” lock washer. Tighten the top end of the rod securely to the buoy frame or instrument cage with a 1-3/4”-10 nut and 1-3/4” lock washer. Weld the connections to prevent loosening in rough water.
