Catalyst is the next step in graphite iron design. Featuring our new Iso-6 material technology, Catalyst is engineered to replicate steel alloy properties over 100% better than traditional graphite laminates. This allows for an extremely stable shaft that maximizes constancy and distance control while providing the benefits of a graphite body design.

Catalyst also features a reinforced tip section which, unlike traditional graphite, delivers torsional resistance comparable to that of steel—improving stability during turf interaction for better impact on less than perfect shots.

We have over 3600 positive feedback at nearly 100%. So, buy with confidence! If you are not happy for any reason, please message us before leaving negative feedback and we will do our best to correct an error!
