I have a master cardiology stethoscope and just replaced the tubing and diaphragm on it. I have had it for about 5 years and LOVE it. It is my third one....the other two were stolen. The one I have now is engraved with my name on it. They also have a serial number on them that you need to write down and keep somewhere safe so if it does get stolen and you see one that you think might be it, you can get your serial number and compare it. Engraving can be changed since it is not very deep, but the serial number will take alot of work to get rid of and smooth out.
