Carabiner

A carabiner is an essential part of any float setup. The pear-shaped carabiner is perfect as it has plenty of space for tethering the dive line to your float. Note that all lines (dive line, or lines tethering the float to other floats, boat, etc.) should be attached to the D-ring on your float. Its stainless steel construction is best for a marine environment because of its rust resistant properties.
