Solid and sturdy wrench. No sign of rust after multiple trips and it hasn’t slipped while tightening tank valves. Worth the investment for any dive technician.

Is this wrench suitable for all brands of scuba regulators or just specific ones? I mainly use it for my Mares and Aqualung sets.

Used the SPW-1/4 spanner for my last regulator servicing. The grip is comfortable and it fits the yoke nuts perfectly, but I wish it came with a protective pouch.
