Training SMB Inflated
Training SMB Inflated Inflation Tube and OPV Dimensions Size Comparison with Standard SMB
  • Compact SMB that can be deployed at depth
  • Closed design with an over-pressure relief valve (OPV)
  • Non-locking low-pressure inflation connector

This small Surface Marking Tube by Mares XR is { 3.3 ft | 1.0 m } long by { 4.0 in | 10 cm } wide. Constructed of 210D nylon with TPU lamination along with a TPU OPV retainer and inflation tube, the bag is RF welded and double stitched plus a 305 stainless steel D-ring at the bottom along with a bungee loop to help make for compact storage. The bag can be inflated at depth via a 305 stainless steel non-locking low-pressure inflation connector that incorporates a one-way valve. The closed design with an over-pressure relief valve (OPV) eliminates the chance that gas will escape from the bag during deployment or once it reaches the surface.

Although the marking tube should NOT be used as a lift bag, for emergency purposes a fully inflated small tube may be considered to have approximately { 5 lb | 2 kg } of lift when completely submerged.

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.
