TRUFIRM OPERATION
The TruFirm meter measures the depth the plunger depresses a surface when it is released from a set height. The value of

The unit is acvated by briey pressing the Buon. The LCD will display the percent baery life for 5 seconds and then
show zeros when it is ready to take a measurement. The TruFirm will power o aer 5 minutes of inacvity.

DATA LOGGING & STORAGE
The data collected by the TruFirm Meter can be viewed on a Smartphone in two formats:
1. Basic Grid Mode - Available with or without a SpecConnect subscripon. The site is divided into a customizable
2-dimensional grid of 3 to 5 rows and 3 to 5 columns. Measurements are taken in each grid cell. Grid cells are color
coded to show the rmness average (Figure 5).
2. Freeform Mode - Available with a SpecConnect subscripon. Color coded locaon icons are placed at every
measurement point using the coordinates from the internal locaon of the app’s mobile device (Figure 6).
The data from the Pro version of the app is sent instantaneously to SpecConnect. Data can be viewed in map form (Figure
7), exported to a spreadsheet, or viewed as a Trend Report (Figure 8). More details are available in the user’s guide for the
app.
The larger the TruFirm value, the soer the turf. The following are general guidelines used to describe rmness
measurements of the TruFirm on greens. With experience, you will see how the rmness measured by the TruFirm
corresponds to ball bounce.
