I was surprised to learn that not all stethoscopes are created equal. The prices range between under $40.00 to well over $500.00 for the most sophisticated electronic instruments.
The ECHO Plus Data Link is an example of a state-of-the-art stethoscope. It is made by the Doctor's Research Group. The sound quality from this instrument is amplified by as much as 400 times the actual volume and can even be be linked to a PC to record patients' hearts.
If I was studying to become a doctor, I believe I would want this instrument. However, it is smart to research all the different types of stethoscopes available on the market beginning with the famous littman stethoscope .
