The Fathom Spool is a rugged and easy to use spool that simplifies tether storage and management for your BlueROV2! Full IP67 water resistance, 8-wire slip-ring, and integrated quick connectors make it tough enough to use at almost any dive site while remaining easy to transport.

Does not include tether! A Fathom-X Tether Interface (FXTI) topside box is required for use, as well as a tether with an installed Binder 770 connector.
