  • Provides great surface visibility from a distance
  • Internal baffle prevents deflating while on surface
  • Includes an OPV to allow excess gas to vent
  • Inflate at depth OR on the surface
  • Includes its own built-in carrying sleeve

When surface visibility from a distance is important, such as when the diver is hanging under a bag during deco, many divers choose the Dive Rite Surface Marking Tube. Similar in operation to a lift bag, but tube-shaped, the Surface Marking Tube is approximately { 5 ft | 1.5 m } tall by { 8 in | 20.3 cm } wide (when flat) with an over pressure relief valve (OPV) and has reflective tape at the top end. The Dive Rite Surface Marking Tube is a hybrid that can be used two different ways:

  • The hybrid marking tube is open at the bottom as with the lift bag and incorporates an ingenious funnel-shaped 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 hybrid marking tube also has an oral/power inflator that allows the tube to be inflated at the surface (like a "safety sausage") 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 an over pressure valve to allow excess gas to vent during ascent and/or to deflate the bag before boarding the boat. Available only in ANSI safety orange, the marking tube also includes its own built-in carrying sleeve. Although the marking tube should NOT be used as a lift bag, for emergency purposes a full tube may be considered to have approximately { 30 lb | 13.6 kg } of lift.

A usage note... the hybrid marking bag is 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.

Tek Tip Warning Image WARNING

This device includes a non-locking hose quick-connect that supports easy and rapid power-inflation at the surface using the standard quick-disconnect low-pressure BC inflator hose. However, there are some safety concerns using that mode for deployment while at depth. Disconnecting the inflator hose from your BC at depth could compromise your buoyancy control in an emergency. Although the inflation connector on the device is non-locking, there is a possibility connectors could jam and fail to easily separate if the connectors are not clean and well maintained. As with any such bag, it is also possible to create enough lift such that it could begin to drag you to the surface if there is any delay in release and the rapid power-inflation feature can reduce the time available before release.

For deployment at depth we suggest using an alternate low-pressure quick-disconnect inflator hose mounted on a stage or bailout bottle, rather than the primary BC inflator hose, for power inflation of this device. If this is your first experience with power-inflation SMB or lift-bag deployment at depth, first practice this type of deployment under controlled conditions.
