Hi, I am a new graduate and need some advice on choosing a new stethoscope for a new job. I will be working as a Medical Surgical Float nurse. Price is not a huge factor, for I plan on using my stethoscope for years to come and want my new job to be easier than harder in areas I can control. I do have trouble hearing with background noise and want my assessments to go as quickly as possible with the help of a new stethoscope. I was interested in a Littman brand. I've read a lot of posts and seems that the electronic stethoscope and the master cardiology are two that I am highly considering. However, I am worried that the electronic might be more difficult to use (have not read to much about how to use this stethoscope though)? Thanks for your help!
