I am a final-semester nursing student; I am fortunate enough to have a wonderful husband (a doctor) who gave me the Littman Cardiologist Electronic Stethoscope with a built-in digital amplifier...though this was a little silly for a first-year nursing student to carry around (you can imagine the stares from doctors, with more than one of them asking what I was doing with such an instrument

), and it was very hard to learn to use (because it picks up EVERYTHING), this stethoscope has opened up a whole new world for me...I plan on going on to become a NP in cardiology, solely because of this stethoscope. I simply can't get enough of it...however, it is very expensive and i spend alot of energy taking care that I don't leave it somewhere. Also, it doesn't hang as comfortable around the neck.
