Update: I started using a cheap fishing line spool to manage my umbilical in a current
Working a job in the Mississippi River last month, the current was pushing my umbilical into everything. I got tired of it getting caught on the barge edge. I grabbed a $12 fishing line spool from a bait shop, tied my umbilical to it, and let it pay out as I moved. It kept the line off the bottom and stopped most of the snags. I saved about 20 minutes of hassle on a 4-hour dive. Has anyone else found a simple tool from another trade that works down here?
