FieldScout TruFirm Turf Firmness Meter
Keep Your Greens Firm, Fast, and Consistent
Measures golf course turf conditions for firm and fast play
Portable, easy-to-use design
Bluetooth capabilities for instant analysis
Based on technology developed by the USGA, the FieldScout TruFirm offers a quick, easy, and affordable method to measure the firmness of turf and bunker sands. Data acquired from the device allows golf course superintendents and sports turf managers the ability to take appropriate actions to reach the desired firmness of golf course greens, fairways, and bunkers, as well as other playing surfaces.
The primary objective for the development of the TruFirm is to improve championship-caliber playability by cultivating greens that are both firm and fast. By measuring the relationship between the compaction of the soil and the moisture level, greenkeepers are able to ensure healthy, aesthetically-pleasing greens that offer exceptional playability. Objective data measurements allow turf management professionals to balance the fine line between soil moisture and firmness, which can challenge even the most experienced experts in the industry.
The patented TruFirm system utilizes a hemisphere-shaped impact hammer that mimics the shape of a golf ball to better simulate golf ball impacts. The mass is dropped from a consistent height and the maximum turf penetration value is recorded and correlated to the surface firmness — the lower the penetration value, the firmer the turf.
