Abstract
A marine survey system includes a collar configured to be affixed to a tow member, to connect a separation member to the tow member and to release the separation member when a lock-release condition is met. Alternatively or additionally, the marine survey system includes a variable drag force mechanism configured to generate a first drag force pushing the collar downstream before the collar reaches a downstream element beyond which the collar cannot move, and to generate a second drag force after the collar has reached the downstream element.
