Featuring 4 in 1 for complete auscultation, this Prestige model is equipped with chest and binaural pieces that are crafted from burnished stainless steel and an pediatric and adult dust swivel head that is integrated with multi frequency. High frequencies can be had by pressing firmly on the skin and low frequencies by pressing lightly on the skin. The instrument is fitted with 2 bell chest pieces for enhanced auscultation and comes with an pediatric and interchangeable head. The ear tips are acoustically sealed and comfortable and feature a screw. The ready to use pre binaural allows for a better listening angle and the dual channel PVC tubing integrated with two independent sound channels ensures optimum sound.
