Thankyou @btrue - some great tips. Haven’t had a chance to deploy mine in the wild yet. So faR just developing some ninja BlueROV skills in the backyard pool (heavy configuration with Ping2D, gripper and Cerulean FS450). Had wondered about tether management as seems as like you’d need an extra hand to spool the tether. Wonder if adding extra ballast would help neutralise the buoyancy with deeper dives?
