Claims

exact text as granted — not AI-modified
What is claimed is:  
     
         1 . A method of operating a range finder, the method comprising: 
 coupling the range finder to a counterweight bar of a bow;    aiming the range finder at a desired target;    activating the range finder;    determining the distance to the target; and    displaying the distance to the target on a display.    
     
     
         2 . The method of  claim 1 , further comprising: 
 transmitting a laser signal to the target;    bouncing the laser signal off of the target;    receiving the laser signal after it has been reflected back from the object;    calculating the transmission time of the laser signal; and    using the transmission time to determine the distance to the target.    
     
     
         3 . The method of  claim 1 , further comprising: 
 depressing an activation button to produce an activation signal.    
     
     
         4 . The method of  claim 3 , further comprising: 
 monitoring for the activation signal; and    when an activation signal is received, determining the distance to a target.    
     
     
         5 . The method of  claim 1 , further comprising: 
 clearing the display of the distance to the target after a select amount of time has past since the distance was first displayed.    
     
     
         6 . The method of  claim 5 , wherein the select amount of time is approximately 30 seconds.  
     
     
         7 . The method of  claim 5 , further comprising: 
 when the select amount of time has not passed, monitoring for an activation signal;    when an activation signal is detected, determining the distance to a target; and    displaying the distance to the target.    
     
     
         8 . The method of  claim 2 , further comprising: 
 coupling a remote control unit that includes the activation button to a riser of the bow for easy activation of the rangefinder during use of the bow.    
     
     
         9 . A method of operating a range finder, the method comprising: 
 coupling the range finder to a bow via a counterweight insert;    aiming the range finder at a desired target;    activating the range finder;    determining the distance to the target; and    displaying the distance to the target on a display.    
     
     
         10 . The method of  claim 9 , further comprising: 
 depressing an activation button to produce an activation signal.    
     
     
         11 . The method of  claim 10 , further comprising: 
 coupling a remote control unit that includes the activation button to a riser of the bow for easy activation of the rangefinder during use of the bow.    
     
     
         12 . A range finder comprising: 
 a range finder circuit;    a display electrically connected to the range finder circuit; and    a mounting structure to mount the range finder to a firearm such that a portion of the display is viewable through an existing scope.    
     
     
         13 . The range finder as in  claim 12 , further comprising: 
 a remote control unit in communication with the range finder control circuit to selectively activate the range finder.    
     
     
         14 . The range finder of  claim 13 , wherein the remote control unit is coupled to a forearm of the firearm.  
     
     
         15 . The range finder of  claim 13 , wherein the remote control unit is coupled to the stock of a firearm.  
     
     
         16 . A range finder comprising: 
 a range finder circuit;    a display electrically coupled to the range finder circuit, the display being adapted to be readable through an existing scope; and    a mounting structure to mount the range finder to a firearm.    
     
     
         17 . The remote control as in  claim 16 , wherein the mounting structure is adapted to mount the rangefinder to the scope of the firearm.  
     
     
         18 . The range finder of  claim 16 , further comprising: 
 a remote control unit in communication with the range finder control circuit to selectively activate the range finder.    
     
     
         19 . The remote control as in  claim 18 , wherein the remote control unit is coupled to the firearm.  
     
     
         20 . A rangefinder comprising: 
 a range finder circuit;    a display electrically coupled to the range finder circuit;    the display positioned such that a displayed distance is readable through an existing scope; and    a mounting structure adapted to mount the range finder to the scope.    
     
     
         21 . The range finder of  claim 20 , further comprising: 
 a remote control unit in communication with the range finder control circuit to selectively activate the range finder.    
     
     
         22 . The remote control of  claim 21 , wherein the remote control unit is coupled to the firearm.  
     
     
         23 . A range finder comprising: 
 a range finder circuit;    a display electrically coupled to the range finder circuit;    the display positioned such that a displayed distance is readable through an existing scope; and    a mounting structure to mount the range finder to a portion of the weapon.    
     
     
         24 . The range finder of  claim 23 , wherein the portion of the weapon is the barrel of a firearm.
