Why do some divers prefer finger spools?

Finger spools are favored by some divers primarily because of their small size and design that minimizes the risk of getting jammed. The compact nature of finger spools allows for a more streamlined profile, making them easier to handle in confined spaces, such as cave environments. This design helps prevent tangling, which can be critical in overhead environments where visibility may be limited and space is constrained.

A major advantage of finger spools is that they enable divers to maintain better control over the line they are deploying. This is particularly important in scenarios where divers need to navigate tight passages or overcome potential obstacles without the line snagging or jamming. The ability to easily deploy and retract the line without complications is essential for maintaining safety and ensuring a reliable means of navigation back to an exit point.

The other aspects associated with their design do not usually outshine this particular advantage that simplifies handling, especially under the challenging conditions encountered in cavern diving.
