Complete review of the Hollis 100' Finger Spool. Analysis of the line, ergonomics with gloves, robustness, and field test results from AquaExposure.
At a depth of twenty meters, towards the end of a drift dive along a steep slope affected by surge, deploying your stage bag requires movements of surgical precision. In this transitional zone where currents accelerate and attention must remain focused on buoyancy, a poorly designed or slippery finger spool can turn a routine maneuver into an unnecessary moment of stress. The Hollis 100’ Finger Spool was designed specifically to meet this requirement for mechanical simplicity and secure grip underwater.
The Hollis 100’ Finger Spool belongs to the family of spool-type guidance equipment, designed for deploying stage bags (DSMBs) and for safety marking. Its mechanical design prioritizes component reliability and ease of control during dives.
Its machined construction allows for smooth handling even with thick waterproof gloves or neoprene. The spacing of the spools and the line guidance have been designed to minimize the risk of derailment during rapid deployment.
The integrated line offers a usable length of 100 feet/30 meters. The high-strength braid provides excellent resistance to abrasion on rocks and oxidized metal.Visually, the contrasting color of the line makes it easier to spot in waters with a lot of particles or during twilight decompression stops. The end of the line has a reinforced termination for a secure attachment.
The ergonomics of a spool are judged by its ability to rotate freely without jerks. The side flanges provide sufficient support to control the braking with your thumb on the edge, preventing the spool from spinning out of control during a rapid ascent of the DSMB. The central hole allows you to insert a finger while wearing thick gloves without the risk of jamming.
Imagine a wood lathe operator guiding their chisel with a smooth motion across a rotating piece. Underwater, the diver uses the pad of their thumb against the side of the spool in exactly the same way, regulating the tension of the line so that the drogue rises straight without creating a loose loop.
The Hollis 100’ Finger Spool is made with top-quality marine materials designed to withstand the corrosive effects of salt, hydrocarbons, and UV radiation. The chassis can withstand impacts against the bottom of the boat or rocky walls without damage.
The precise machining of the surfaces eliminates any extraneous axial play, ensuring smooth and consistent rotation over time.
The peripheral anchor points allow the line to be securely locked in place at rest with a double-ender carabiner to prevent any accidental unwinding in the thigh pocket.
The price point of the Hollis 100’ Finger Spool reflects the quality of its construction and its mechanical robustness. It is a piece of equipment designed to last for years of intensive diving without weakening, provided it is simply rinsed with fresh water after each dive.
