With both robust and lightweight construction, this composite reel comes equipped with a sliding stainless steel line guide that aids in the uniform rolling of the line and also prevents entanglements. Includes two mounting brackets that will allow you to mount this versatile reel to just about any speargun. Extruded aluminum or plastic track spearguns such as the Evolution, Rob Allen, Aimrite, or Rabitech are no problem. Screw the included mount bracket into wood spearguns such as hybrids, Riffe Euros, and customs. This Reel was also specifically designed with cutouts in the spool which aids in the drying time of the line spooled, while simultaneously reducing the overall weight of the reel. 4.5oz total weight (without line) Reel Line capacity is approximately 30 meters (100ft) of a 1.5mm diameter line or 80ft of a 1.8mm diameter Line. The line is not included. Features: Robust & Light Weight Versatile Mounting Simple Line Management 80ft Capacity using 1.8mm diameter line (can hold up to 100 feet using 1.5mm diameter line)
