SDN Members don't see this ad. (About Ads) i know, generic question. over the years i've heard lots of talk about the littman tunable diaphram, both good and bad. i have a littman cardio III and it serves me well, though during an actual exam i can't recall switching between the bell/diaphram mode. i can't recall being unable to hear something an attending heard and i have picked up some subtle stuff (though i've undoubtable missed some, too). anyway, i'm bored and looking at stethoscopes on the internet. not that i'm unhappy with the littman, i'm just curious about some other scopes that might be worth listening too. thoughts?
