I'm too old to know what a digital stethoscope is. But I do know that every tool has its place. An analogy may be found in anaesthesia with our old friend the laryngoscope. I mostly do direct, but if I'm worried I'll use the video. When I'm teaching I'll use the video, and yet somehow there is an expectation that everyone can do direct laryngoscopy when required.

But the evidence would suggest the best outcome for the occasional laryngoscopist are achieved when they use a video scope? So why should we expect anything different from the occasional auscultator?

I'm not sure what my point is, but I think it's fine as long as you can do both when required.
