its a baseball dat shows how fast you throw but l dont know how to use it

how to put the feet and stuff

you just throw it and it shows you

If u mean a radar gun :

SETTING UP THE RADAR GUN
1. Turn on ''power”
2. Push ''self test'' or use calibration fork (included)
3. Push ''set up'' mode. Use ''A-25'' recommended for skeet. Speeds r recorded in 1/10 MPH
and the gun disregards all movements slower than 25 MPH
4. Push ''x-mit'' button-turns on transmitter
5. Push ''peak-hold'' button -display fastest speed only

Other than that, throw the ball & see what the speed is from the radar gun.

Hope this helps.
