Full review and test of the OMS stage parachute- nylon stage parachute with 1m valve- Closed OMS TEK (100 cm). Analysis of visibility, inflation safety, and field verdict from AquaExposure.
At the end of a drift dive, suspended at a depth of five meters in the blue, as the current carries you away from the reef, the lift bag is your only link to the surface. In a choppy sea where waves and foam obscure the silhouettes of divers, a lift bag that is too short or that deflates upon contact with the waves becomes a critical hazard. The OMS Parachute lift bag, made of nylon with a 1-meter closed valve, OMS TEK, has been developed to ensure perfect verticality and immediate visual signaling for support boats.
Design and Architecture of the OMS Parachute lift bag, nylon with a 1-meter closed valve, OMS TEK
The OMS Parachute lift bag, nylon with a 1-meter closed valve, OMS TEK, is designed with a closed-tube architecture, 100 cm in length. Its high-visibility orange color has been chosen to provide maximum contrast on the water, minimizing the effects of sunlight reflections and marine foam.
Its internal volume guarantees sufficient positive buoyancy to tension the spool line without excessively pulling on the diver during the safety stop. The integrated SOLAS reflective bands significantly increase optical visibility during twilight or low-light dives.
1. Inflation, Air Management, and Purging (D1: 4.6 / 5 - Weighting 35%)Safety during deployment relies on a versatile and secure inflation system. The OMS Parachute de palier nylon valve, 1 meter closed, OMS TEK design, allows for controlled air injection, preventing sudden overpressure during a rapid ascent to the surface.
The presence of a calibrated overpressure valve with a manual purge pull allows for the evacuation of excess air during volume expansion. On the surface, the anti-return valve prevents any accidental deflation when the line slackens on a wave crest.
2. Visibility at a Distance and Surface Silhouette (D2: 3.0 / 5 - Weighting 30%)
With its straight 100 cm profile, this model stands proudly above the waterline, offering boat lookouts an optimal sighting angle from hundreds of meters away.
Imagine a maritime signaling buoy subjected to swells: if its air volume escapes from the bottom or if its structure lacks rigidity, it will sag on the water and disappear between the waves. The OMS Parachute de palier nylon valve, 1 meter closed, OMS TEK design, operates on the principle of a sealed column under pressure. Once deployed, its anti-return system and valve maintain a perfect straight geometry for visibility from a distance.
3. Materials, Welds, and Mechanical Strength (D3: 4.2 / 5 - Weighting 20%)The durability of a lift bag depends directly on the quality of its fabric and the watertightness of its seams. The OMS lift bag, made of 1 meter nylon with a valve, closed, OMS TEK model, uses a high-tenacity nylon fabric coated with thermoplastic polyurethane (TPU), assembled with watertight high-frequency welds.
This construction remarkably resists repeated friction, abrasion from salt, and premature aging caused by UV rays during prolonged surface exposure.
4. Ergonomics, compactness, and storage (D4: 3.4 / 5 - Weighting 10%)
Once deflated and rolled up, the OMS lift bag, made of 1 meter nylon with a valve, closed, OMS TEK model, has a minimal footprint that easily fits into a thigh pocket or under a stabilizer vest strap.
The stainless steel D-ring located at the base allows for direct and secure attachment of your finger spool with a double-ender made of stainless steel.
5. Quality, price, and consistency (D5: 3.0 / 5 - Weighting 5%)
Priced at a suggested retail price of €41, this model offers a level of technical performance perfectly aligned with the safety requirements of modern diving.
