Holding a chest piece by hand often generate artifacts that make visual
display unreadable. If you have this problem (and most people do), we
suggest that you attach the chest piece to skin so that you do not need
to hold it. There are several attachment methods you can use:
1. Just place the chest piece on bare skin. If the chest piece is heavy
enough it will stay in place.
2. Attach the chest piece with 3M Double Stick Discs (SKU B11687). You
can order it here: 3M
Double-Stick Discs pack of 102 Size 1 1/4" 3M SAS2349 (HC) 3M 2181 (Pack).
3. Use a rubber belt to hold chest piece in place. We prefer maternity
belt used to hold a doppler monitor in place when the hospitals want to
hear the fetal heartbeat for an extended time. It's made of very soft,
pliable and stretchy material. You can order it here: www.utahmed.com,
