Thinking of buying a fetal doppler?

A fetal doppler is an important device for obstetricians and midwives. We have seen that a lot of babies die because hospitals do not have quality devices. In my home country Paksitan, hospitals and midwives who work in small cities and rural area, do not have these kind of devices.
Buy should buy read fetal doppler reviews before buying one. It will enable them to understand the features offered by different makers.
