MARES SMB XR

Designed for demanding diving environments, the Mares XR Surface Marker Buoy provides reliable surface signalling and enhanced visibility during ascents, safety stops and drift dives.

Constructed from durable, welded and double-stitched material, this closed-circuit SMB features an integrated one-way inflation valve compatible with oral inflation or a low-pressure inflator hose. An integrated over-pressure valve (OPV) allows excess gas to escape during ascent, helping prevent over-inflation.
A transparent pocket at the top accommodates wet notes or a glow stick, while SOLAS-approved reflective tape improves visibility in low-light conditions. Finished with a stainless-steel D-ring and bungee attachment for secure deployment and compact storage.
