The FreeDop™ is a cordless, portable, counter-top Doppler. With easy-to-use touch controls and a unique smart charging stand, the FreeDrop features meet the demanding requirements of users. The unique cordless probes are compact and offer convenient volume and on/off controls right at your finger tips. Use the 2 MHz or 3 MHz obstetric probes to hear the fetal heartbeat.

The dual speakers produce Doppler sounds that are crystal clear and free of distortion.
