Youthful exuberance drove me to pilot my OpenROV before I built a good tether management system. Bad idea! It’s better to have a tether management plan (any plan) before you pilot your OpenROV.
This article describes a tether management system that works for me. Other OpenROVers have devices that work, too. Take a look at a few and eventually you will find one that fits you.
This tether management system is constructed entirely from off-the-shelf parts. The main component is an extension cord reel sold by Home Depot for about $14.00. Buy it, gut it, add the slip ring using three screws (also from Home Depot) and you’re good to go.
