Exclusive to STI, NP50 is a cross-stitched, nylon putting surface. NP50 perfectly replicates bent grass putting greens. This is as close as you can get to the real thing. NP50 is found at premiere golf courses, teaching and training academies, including David Leadbetter’s World Headquarters Champions Gate, Florida. The surface is ideal for instructional purposes, as it maintains its “true roll” characteristics irrespective of temperature, climate, time of day or time of year. This consistency is a welcome tool for any teacher or student of the game. In addition to instructional settings, STI’s NP50 is found in many residential putting greens and retail and entertainment environments.  Serious golfers demand the true roll, consistent and realistic characteristics of NP50. For the person serious about improving their putting stroke, NP50 irrespective of the setting is the preferred putting surface.
