The CROC Tether Reel series by Reach Systems delivers unmatched durability, portability, and flexibility for remote and autonomous systems deployment. Engineered for professionals working with ROVs, robotic crawlers, sonar systems, and Autonomous Surface Vessels (ASVs), the CROC reels are built to perform in demanding field environments.

Available in three sizes to suit any application, each CROC reel offers reliable manual payout and retrieval as a baseline, with a full suite of upgrade options — including motors, level winds, and distance counters — to match your operational needs. And with the Smart Winch option, any CROC reel can be operated remotely over wireless networks or configured for semi-autonomous payout and retrieval, giving your team greater control with less manual effort.

Whether you need a compact reel for portable deployments or a heavy-duty solution for large-diameter cable, the CROC series scales with your mission.
