The YASI Replacement Spool Line is a durable, high?visibility flat line designed to refresh or upgrade any standard scuba spool or reel. Whether you’re sending up a DSMB, navigating low?viz water, or running technical jumps, this 45?metre nylon line gives you reliable performance without tangles or fraying.

Made from tough, abrasion?resistant nylon, it lays smoothly and evenly on the spool, resists knotting, and stays flexible even after long saltwater dives. The bright fluorescent orange colour makes it easy to see underwater, helping you track your line quickly in dark or silty conditions. It fits cleanly onto most aluminium, plastic, or composite finger spools and compact reels.

• 45?metre length — Ideal for DSMB deployment, cave or wreck navigation, and technical decompression work.
• Flat?weave design — Packs neatly in smooth layers to prevent twisting, binding, or line nesting.
• High?visibility orange — Easy to spot in low?light or low?visibility environments.
• Abrasion?resistant nylon — Strong, flexible fibres that hold up against rock, wreck metal, and general wear.
• Universal fit — Works with most standard diving spools and compact reels.
• Hydrophobic blend — Resists waterlogging so the line stays light, smooth, and easy to handle.
