Mares XR Surface Marking Tube { 4.6 ft | 1.4 m }
The Mares XR SMT is available in your choice of safety orange or yellow, and includes SOLAS reflective tape for extra visibility plus a transparent vinyl window at the top for inserting messages or glow sticks. The height at the surface for the Mares XR SMT is approximately { 4.6 ft | 1.4 m }, and measures { 6.0 in | 15 cm } wide when flat. Constructed of TPU laminated 210 denier nylon along with a TPU OPV retainer and inflation tube, the bag is RF welded and double stitched and includes a stainless steel D-ring at the bottom and a bungee loop to help make for compact storage. The bag can be inflated at depth or on the surface via a 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 once it reaches the surface.
Although a marking tube should not be used as a lift bag, for emergency purposes the fully inflated tube may be considered to have approximately { 13 lb | 6 kg } of lift when completely submerged.

Customer Reviews
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 either a Y-adapter or an alternate low-pressure quick-disconnect inflator hose mounted on a stage or bailout bottle, rather than disconnecting 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.
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.
