Trident Aluminum Reel with Tension Locking System Blue 250

In the early days of cave diving reels were not available to buy off the shelf. Divers used anything they could including empty electrical wire spools. When exploring divers would pay-out the line and if they didn't empty the entire spool it would be left in the cave for the next dive since winding the line was difficult if not impossible. The Aqua Aluminum Primary Reel is a large diver's reel designed for cave and wreck diving.
