A percussion hammer and pleximeter may be purchased from any veterinary instrument maker.
Moreover, one always has his hands, but may forget his hammer and pleximeter.
Percussion is sometimes practiced with the aid of a special percussion hammer and an object known as a pleximeter to strike upon.

A small thin plate held against the body and struck with a plexor in diagnosis by percussion.
