This OMS Slim Surface Marking Tube is approximately { 6.0 ft | 1.8 m } by { 5.0 in | 13 cm } (when flat) and designed with a semi-closed bottom allowing the diver to inflate it using the using the second stage of a regulator. The bag can also be inflated at depth or on the surface via a non-locking low-pressure inflation connector that incorporates a one-way valve and also can be orally inflated. An integrated { 0.5 lb | 0.2 kg } lead weight at bottom and slim design assists with deployment and maintaining stable upright visibility even in rough seas. Coast Guard approved SOLAS reflective tape across the top of SMT creates better visibility day and night. The OMS Deluxe SMT also includes a transparent vinyl window at top for inserting messages or glow sticks. Sewn-in webbing loop with stainless steel D-ring, along with hook and loop strips at bottom to keep the SMT tidy for storage.

The semi-closed design is a hybrid of open and closed types that can be used two different ways:

  • The tube is open at the bottom as with the lift bag and incorporates an funnel-shaped (aka 'duck-bill') internal baffle that allows the tube to be inflated as usual with a regulator second stage at depth, but prevents the tube from unintentionally deflating should it fall over while on the surface.

  • The marking tube also has an oral/power inflator that allows the tube to be inflated at the surface or at depth. Perfect for rebreather divers, using the oral/power inflator with the low pressure hose on a bailout bottle makes inflation manageable without the use of diluent gas.

The hybrid marking tube includes a compact over pressure valve to allow excess gas to vent during ascent and pull dump to deflate the bag before boarding the boat or when being rolled up for storage.

Note: The hybrid marking tubeis not fully closed by design and if you inflate it when dry (i.e. at home, to 'test' it), you will discover gas slowly leaks out through the bottom baffle. This does not cause a problem in actual in-water use, where the water will cause the baffle to seal. Although the marking tube should NOT be used as a lift bag, for emergency purposes a fully inflated tube may be considered to have approximately { 30 lb | 13.6 kg } of lift when completely submerged.

What Color is Your Parachute Bag?

Studies done in the transportation sector prove the best color for high visibility worker clothing is fluorescent safety orange because that color is the most visible from the greatest distance. A fluorescent yellow-green color, while not as visible at distance, offers better night visibility and is also a better choice for signage because it provides more contrast for lettering.

Some groups of divers have informally assigned meaning to bag color. Shooting an orange bag or marker is supposed to indicate a normal situation to surface support. The appearance of a yellow color may mean that the diver has an abnormal situation and requires assistance from the surface. However, there is no color standard along with considerable confusion about color.

Our recommendations: If visibility is most important, then orange is proven by far to be the best color choice for distance visibility during daylight hours. Choose yellow for night visibility, or for a day and night compromise we offer a marking tube that is yellow on one side and orange on the other. We respectfully suggest reconsidering any dive plan which depends on the color of a bag to signal for help.
