How do I use an UltraScope or MaxiScope?

Binaurals should point toward your nose and ear tips should seat fully and comfortably into your ear canal opening.

Hold scope head between your thumb and middle finger. Apply (or release)pressure using index finger of the same hand. Use LIGHT pressure to start. Pressing too hard will block sound.


How do I hear lung vs. heart sounds with an UltraScope?

To hear HEART sounds (low frequencies) start with very LIGHT pressure.
To hear LUNG sounds (high frequencies) apply FIRMER pressure.
Use MEDIUM pressure for taking blood pressure readings.

In noisy environments, you can cup your hand over the headpiece. Be careful not to press too firmly, as too much pressure can block out all noise.


Why can’t I hear anything?

Remember: Pressing too hard will block out all sound!

Are ear tips in ear canal properly? 
The ear tips should point slightly away from your body. Try using them in the other direction. Is the fit better?

Do the metal binaurals feel twisted in your ears? 
Hold both the binaurals/ear tips in your hands, pointed away from your body. Gently push them away from you to align, using equal pressure. Is the fit better? If you over correct, simply push the binuaurals/ear tips in the opposite direction. 

When you tap on the diaphragm, does it make a drum sound?
If not, your diaphragm is loose. Tighten by holding the head and turning the Retaining Ring clockwise.

Are you in a noisy environment?
Place entire palm over headpiece and apply the correct pressure using the palm of your hand.

Is pressure too light, allowing ambient noise to come in under the head?

Which UltraScope model is the best for hearing impaired and hard of hearing individuals?

The UltraScope Classic Stethoscope is sometimes recommended for hearing impaired medical professionals. However, we strongly recommend they try the Single model first.

Why try the Classic model?

  • If you say, “My scope doesn’t sound the way it used to.”

  • If you have high or

    low frequency

    loss in either ear.

(In-the-ear hearing aids must be removed to use the UltraScope.) 

When is the Classic not for you?

  • When you can hear better with the UltraScope Single model stethoscope over your existing stethoscope.

  • When the sound of the 2 (classic) tubes rubbing together is annoying. (This is common for people with good hearing)

For more information please refer to our Hard of Hearing testimonials. Or please call our live customer service department to discuss which model would be best for you: 877-633-8688, Monday – Friday between 8am-5pm EST.



How do I clean and care for my UltraScope or MaxiScope?

Please read our Care and Cleaning Instructions

  • Use an alcohol wipe to clean the head, eartips, diaphragm, and retaining ring only. Please DO NOT soak any part of your stethoscope in liquid.

  • A cloth dampened with water and antibacterial soap can be used to clean any part of your UltraScope. Wipe well with a damp cloth until all soap is removed. Dry completely.

  • The tubing can be “shined” with a cloth sprayed with non-solvent or non-petroleum distillate polish such as Pledge®.

  • UltraScope can be sterilized in any

    low temperature

    gas sterilization such as Anprolene® by Andersen Products

  • Do you see threads where your ear tip is missing? If yes, place a tiny drop of super-glue on the threads. Screw on your 2 part metal and soft PVC eartip and dry 10 minutes prior to use.

Please Note: Normal usage may loosen the retaining ring. Check your scope before use. Occasional tightening of retaining ring may be required.

How much do the UltraScope and MaxiScope weigh?

Most of our models are 6 oz. and under. 

My UltraScope paint looks different than what I saw online. What happened?

All of our designs are individually hand painted. This means that there are going to be some variations and it may not look exactly the same as the image you see online.


Can I buy multiple head designs separately?

UltraScope only sells our products as a whole unit. Interchanging of heads in stethoscope tubing can wear and stretch your tubing quickly. This can cause your chestpiece to fall out and become lost. (UltraScope does not warranty lost heads.) If you’d like to purchase multiple designs or head sizes, consider the UltraScope Duo Stethoscope that quickly and easily screws between different heads without compromising your tubing.

If you currently own a Single, Duo or Trio Model and would like to Upgrade to purchase additional heads, please contact Customer Service

Which head size do I need for my stethoscope?

We recommend Adult size head for patients 45 lbs (20 kg) and up. Pediatric size head for patients 5 lbs - 45 lbs (2 kg - 20 kg). A pediatric nurse explained, "Using the adult size UltraScope on a small pediatric patient is too risky. Good lung sounds could migrate over to the bad lung, thus being misinterpreted." It's up to each practitioner to make this decision based on our recommendations and their judgement. It is always best to use the correct size head for patient's size and weight.
