Based  on  technology  developed  by  the  USGA,  the  Field 
Scout TruFirm Turf Firmness Meter is used to measure the 
firmness  of  sports  playing  surfaces,  especially  golf  greens, 
fairways  and  bunkers.    The  device  consists  of  an  impact 
plunger  and  a  rotary  position  sensor.    Once  motion  of  the 
plunger  is  detected  the  electronics  will  collect  and  process 
the  signal  and  send  a  measurement  to  an  LCD  display.  
The  measurement  may  also  be  streamed  to  a  handheld 
device  via  a  wireless  communications  protocol  using  a 
Bluetooth accessory (items 6490S, 6491S).
