Frequently Asked Questions (FAQ)

Q: What is the warranty period for a Cardiology IV and Master Cardiology Stethoscope?
A: 7 years

Q: Is there a difference in acoustic quality between the different finishes of stethoscopes models? Is the mirror finish Cardio IV a better diagnostic stethoscope than the standard finish Cardio IV?
A: No - the finishes and colour options are cosmetic only - the do not enhance the quality of the stethoscope. If you close your eyes when listening with any Cardiology IV style you can not tell the difference.

Q: What is the difference between the Cardiology IV and the Master Cardiology stethoscope?
A: The main differences between these two stethoscopes is that the Master Cardiology is heavier, has a higher performance rating, and has a single-sided chestpiece suitable only for adults. A Cardiology IV has a double-sided chestpiece, allowing it to be used on pediatric and adult patients. 

Q: Is the Cardiology III still available?
No the Cardiology III was discontinued several years ago. The Cardiology IV has replaced it.

Q: Are there other colour options available beyond what is online?  Can I mix and match colours and finishes?
Unfortunately not. We have all of the available colour schemes on the website. Customization of colours and finishes are not available.
