The key to custom club fitting is ease of operation. Golf pros need to be able to switch heads and shafts with as little time in between swings as possible. In developing the Opti-fit Driver cart, we took into account the time required to switch a club head from one shaft to another. The shafts are all positioned in easy slide out tubes allowing complete access, but holding them securely during transport. The heads are secured in custom drop in mesh cages so they can quickly and easily be removed and fitted. During transport, the heads are secured with quick snap bungee cords to prevent damage. Additionally, we added a custom iron fitting feature. Carts can be intermixed with woods and irons based on the golf shop specification allowing them to serve their customers as they see best.
