The Hammorhead Remora Reels allow a slow controlled tension to stop the escape of fish or to ascend back to the the surface if your shaft is stuck. Diving with a reel also allows you to anchor your safety float rather than drag it with you. HD CONSTRUCTION Durable Stainless Steel sliding bracket, line guide, and axel. Smooth drag washers apply even tension to the line. Nylon composite spool and side plates reduce weight. UNIVERAL SYSTEM Horizontal mounting brackets quickly attaches to all HammerHead Speargun models.
