The Ultrascope Extended is an excellent choice for special uses including large animals, obese patients or sub-zero temperature applications. The tubing extension allows for total assessment of the patient and the same excellent assessment as our other UltraScope models. The tubing extension removes easily for conversion to standard 30" length for clinical use. For sub-zero applications, this stethoscope can be worn under a coat and the head easily slides in and out of the sleeve or gloved hand for use. Obtain all sounds even while listening through your glove.
