Technical analysis and reasons for excluding the BigBlue yellow stage parachute, 1.8m. Why this model is excluded from the recommended AquaExposure selection (yellow color).
Safety at sea is never compromised for aesthetic or commercial reasons. While the AquaExposure catalog features a wide range of diving equipment, certain products are deliberately excluded from our recommended selection. This is the case with the BigBlue yellow 1.8m stage parachute. The reason for this exclusion is: Yellow color. This technical sheet aims to transparently explain the practical and safety reasons that motivate this editorial choice.
The BigBlue yellow 1.8m stage parachute, manufactured by the BigBlue brand, is a model of signaling parachute (standard length) available on the diving market. While it may be attractive due to its price or visual appeal, its technical design directly contradicts the safety and marine environment protection standards established by AquaExposure.
Our evaluation system applies strict exclusion rules even before calculating a numerical score. A stage parachute is a survival tool, not a gadget.
In the field, these design flaws translate into risky situations:
AquaExposure does not recommend using the BigBlue Parachute, yellow, 1.8m, as a primary signaling device. For your safety and to respect marine ecosystems, we encourage you to choose a closed-tube parachute in orange or pink, equipped with an overpressure valve and connected to a separate spool.

This model is excluded from our selection because of: Its yellow color, which does not guarantee optimal safety at the surface.
AquaExposure strongly recommends using a high-visibility orange or pink surface marker buoy (SMB) for maximum contrast against the water.
Yes, a lead weight striking the seabed can break coral and damage Posidonia seagrass beds.
A closed or semi-closed tube with a non-return valve and a calibrated overpressure valve is the safest standard.
