I have posted on this topic before...Here is the info on the steth I have had for several years. It is from Dixie EMS. I have had great success with this steth and really like to use it!
the following is copied from the Dixie EMS website:
Lighter! So much easier to wear! Better sound quality! No extra parts to lose! Fits infants, too!
The Dixigear high-density Pot Belly head requires no metal bell to act as a sounding board, because it filters out external noise while it amplifies heart/lung sounds. This custom scope can be used on bare skin, or can be clearly heard through up to eight layers of fabric! Two types of eartips come standard assuring custom ear fit comfort. Your choice of designer colors to coordinate with your professional wardrobe. Full three-year warranty.
Here is the link to their site:
Click on "diagnostics" and you will be taken to their selection of stethoscopes. They are a great company to order from. I received my order very quickly!
Good luck to you as you begin your career!!
