Product Information
A solid Delrin spool for deploying surface marker buoys and navigation lines, with 100 ft (30 m), 150 ft (35 m) or 200 ft (60 m) of #24 line. Its solid center keeps the spool diameter small and removes the risk of catching a finger while line pays out.
Who it is for
This spool suits recreational and technical divers who need a compact, reliable way to shoot an SMB from depth or run a navigation line. The compact solid-center design is snag-resistant and easy to stow for deploying surface markers or navigation lines.
Key details
- Material: solid Delrin (acetal), a nearly indestructible build for years of trouble-free operation.
- Line: #24 line, in 100 ft (30 m), 150 ft (35 m) or 200 ft (60 m).
- Hardware: marine-grade bolt snap, supplied as a stainless steel double ender.
- Design: solid center reduces spool size and eliminates finger-catch risk during deployment.
Compatibility and sizing
Choose the line length to match your planned depth: longer lengths give more margin when shooting an SMB from deeper stops, while shorter lengths stay more compact. An adapter is available separately to retrofit any Defender Pro size. Note that this is the base Defender model and not the Defender Pro, which uses a different grip and spin design. This product carries a California Proposition 65 warning.

Frequently Asked Questions
Which line length should I choose: 100 ft, 150 ft or 200 ft?
Match the length to the depth you plan to shoot an SMB from. The Halcyon Defender Safety Spool is offered with 100 ft (30 m), 150 ft (35 m) or 200 ft (60 m) of #24 line. Longer lengths give extra margin when deploying a surface marker from deeper stops; all options use #24 line.
Does the Defender Safety Spool come with a bolt snap?
Yes. Each Halcyon Defender Safety Spool includes a stainless steel double ender, described by Halcyon as a marine-grade bolt snap. No separate hardware purchase is needed to start diving with it, though a retrofit adapter for Defender Pro sizes is available separately.
What is the difference between the Defender and the Defender Pro spool?
They are two distinct Halcyon products. This listing is the base Defender Safety Spool: solid Delrin with a solid center that reduces spool size and prevents finger catches during deployment. The Defender Pro is a separate model with different features, including an Easy Grip adapter and free-spin and locked positions. An adapter is available to retrofit any Defender Pro size.
Why is Delrin used for a dive spool?
Delrin, an acetal plastic, gives the Defender Safety Spool a nearly indestructible body with smooth, low-friction handling so line pays out and rewinds cleanly. Halcyon describes the solid Delrin design as nearly indestructible, giving years of trouble-free operation.
