The most recognizable form of the stethoscope has been dangling from doctors' necks since the 1940s. That analog device helps physicians monitor sounds, such as your heartbeat, to gauge your health. With the Model 3200 electronic stethoscope, though, this old-school medical tool is getting a serious upgrade.

The Model 3200 is equipped with ambient noise reduction technology, which means it filters out unrelated background noise to help doctors focus on sounds that matter most. It also has extra amplification when needed. And that's just for starters.

With this product, doctors can even record sounds and listen to them again later in an effort to create a more accurate diagnosis. Integrated Bluetooth means sound data can be transferred immediately to a computer and stored with a patient's medical file and shared online with specialists.
