Professional quality
Being in the medical profession I have used many fetal doppler devices in the past and the sonoline b is literally the best and the most cost effective fetal doppler for regular use for doctors and ultrasound technicians. The sound quality is great. The price is low, and the 3mhz probe easily detects a heart beat. The device was very easy to use, just as any other fetal doppler. I think the ultrasound gel, however, should be included for free
