Review: Nice, well constructed DSMB - Very decent DSMB Pros: multiple ways to inflate (mouth, inflator hose, regulator). Reflective tape on top. Heavy duty material and construction. Aluminum finger spool. Stainless swivel. Purge valve. 60ft of line. Stanless d ring attachment. Velcro and bungee keeps it securely rolled up. Cons: spool is small for 60ft of line making it difficult to get clip through holes (I cut 10ft off which helped resolve the issue). Loop to attach to smb d ring is on the small side but workable. A bit on the bulky side. Takes a number of breaths to inflate (easier to do with regulator). Overall very satisfied with this DSMB for the price point.
Review: Muy bien - La boya es buenísima. Funciona perfecto. El carrete es más pequeño de lo que me hubiera gustado y el cordel utilizado no me gusto (por ser plano y se riza con extrema facilidad)
