Halcyon
Defender Spools
For any diving application
where the diver will use less than 150 feet of line. The spool
provides rapid, jam free deployment and retrieval. Perfect in
the ocean for deploying lift devices or while cave diving as jump/gap
or safety spools. For cave diving, a 150' spool is recommended
for safety.

Halcyon 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.
