SEA-GEAR Brass Button Messenger, 1500-91B is a two-pound (91kg) general-purpose actuator designed for use with water bottles, plankton nets, double-release mechanisms, and other on-wire underwater devices. It offers a smooth cylindrical body without protrusions. The spring-loaded button slides back when pressed against the up to 5/16” (.82cm) hydro-wire. Depressing the button for cable removal is an easy task for cold, wet, left, or right hands. The messenger is equipped with a nylon lanyard for use with sequentially operated instruments.

Model 1500-91T Teflon Button Messenger conforms to the same critical design requirements as the brass version and offers the same ease of operation for applications in which any metallic contact is undesirable.
