The Aquacare unit has two types of hand pieces.
Gold Hand piece
This hand piece has a large opening (0.8mm) and is used for the larger surface work. You can recognize this tip by the golden ring. Only the cutting/polishing tips can be used on this hand piece.
Silver Hand piece
This hand piece has a small opening (0.6mm) which is suited for the more precise work. You can recognize the tip by the silver ring. You can use both the cutting/polishing tip and the interproximal tip on this hand piece.
