Forming finger spools from metal offers durability, of course, but also allows greater freedom in design that yields the most compact form factor possible for a given amount of line. Metal construction almost doubles the capacity compared to plastic or POM with a thinner profile and more perimeter holes closer to the edge.

These premium quality Aluminum Finger Spools are available in your choice of four different lengths of line on two sizes. The Large size is { 3.0 in | 7.5 cm } in diameter, { 1.6 in | 4.1 cm } in width, with a { 1.0 in | 2.5 cm } center hole. The Small aluminum spool is { 2.4 in | 6.1 cm } in diameter, { 1.9 in | 4.8 cm } in width, with a { 0.8 in | 2.0 cm } center hole. All are made from an aluminum alloy, anodized for a long corrosion free life. Unique to this design, the edges of the spool itself have been knurled for a secure grip and the sides have been curved to improve ease of use during deployment. All spools include a { 3.5 in | 9.0 cm } heavy duty 316-series stainless steel double eye bolt snap. This size snap offers minimal 'dangle.' To help prevent twisting, a brass/stainless steel line swivel is attached between the end of the orange line and a leader loop of neon yellow line with shrink wrapped ends.

Choose different line lengths depending on intended use, and easily distinguish each reel by the color. The orange line featured on our Aluminum Spools is better than the generic nylon line commonly used in diving applications because it is high tenacity. Similar to our Hi-Viz Orange Dacron line, but with a different construction. The line measures { 0.12 inches | 0.30 cm } x { 0.024 in | 0.060 cm }, giving it a flat appearance. This feature makes it easier to detangle. Dacron line costs a bit more than generic nylon line, but this abrasion resistant line has slightly negative buoyancy, won't twist or kink, and has minimal stretch. White nylon line is difficult to see in open water, but orange line stands out like neon, allowing easier line management with nearby divers.
