Guideline Devices

Halcyon reels and spools have established the industry standard for quality construction and trouble-free use. Historically, guidelines were associated with navigation during cave dives; however, they are equally useful in a range of diving environments. From shooting a lift bag and marking an underwater location to surveying wreck sites and sending up surface markers, you are sure to find a Halcyon product that fits your needs.
Defender spools are one of many unique products introduced by Halcyon. The Halcyon Defender spool blends uncompromising quality with ideal weight characteristics, allowing ease of deployment and years of trouble-free use. Halcyon Defender spools are equally at home navigating through caves or shooting a surface marker while ascending from your favorite ocean dive.

Coldwater Defender Spool

Thick gloves and cold fingers can make it difficult to use a spool; gloved fingers overlap the edge of the spool and cold hands make it hard to grip small edges. Halcyon solved this problem by creating the industry’s only built-in handle. The flanged edge around the Halcyon coldwater spindle allows the spool's double-ender to act as a handle.
