Stainless Steel Standard Finger Spool- 20/30/50m (ref. 36717): Test, features, and diving reviews (2026).

At a depth of twenty meters, towards the end of a drift dive along a slope affected by surge, deploying your lift bag requires movements of surgical precision. In this transitional zone where the current accelerates and attention must remain focused on buoyancy, a poorly designed or slippery finger spool can turn a routine maneuver into an unnecessary moment of tension. The "Doigt Inox Standard" finger spool (reference 36717) was designed specifically to meet this requirement for mechanical simplicity and secure grip underwater.

The "Doigt Inox Standard" finger spool (reference 36717) belongs to the family of spool-type guiding devices (20 meters, 30 meters, 50 meters), designed for deploying lift bags (DSMB) and marking safety lines. Its mechanical design prioritizes component reliability and ease of control underwater.

Its machined construction allows for smooth operation even with thick waterproof gloves or neoprene. The spacing of the flanges and the line guide have been designed to minimize the risk of derailment during rapid deployment.

Visually, the contrasting color of the line makes it easier to spot in waters with suspended 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 even with a thick glove without the risk of jamming.

Imagine a wood lathe operator guiding their gouge with a smooth motion across a rotating piece. Underwater, the diver uses the pad of their thumb against the edge 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 construction of the "Doigt Inox Standard" spool, available in 20/30/50 meter versions (ref. 36717), uses top-quality marine materials designed to withstand the corrosive effects of salt, hydrocarbons, and UV radiation. The frame can withstand impacts against the boat hull or rocky walls without damage.The precise machining of the surfaces eliminates any parasitic axial play, ensuring smooth and consistent rotation over time.

The safety of a spool relies on the complete absence of sharp edges that could potentially damage the line under high tension. The internal and external bevels guide the line without abrasive friction. In the event of a sudden pull caused by a parachute being dragged by a surface wave, the system allows for immediate release without trapping the hand.

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 positioning of the Doigt Inox Standard Finger Reel 20/30/50m (ref. 36717) 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.

The Standard Stainless Steel Finger Spool 20/30/50m (ref. 36717) establishes itself as a solid and effective reference in its category. Whether you are looking for a reliable signaling tool for drift dives or a navigation spool for your advanced dives, it provides a clear and proven technical solution.
